+description: "Perform a repository-grounded secure code review with evidence-first findings, repo-aware prioritization, and remediation guidance for GitHub Copilot users."
+---
+
+# Secure Code Review
+
+## Purpose
+
+Provide a durable, evidence-first secure code review workflow for GitHub Copilot users reviewing a repository or PR diff. This skill is designed to produce grounded findings, practical remediation guidance, and a report that can be reused in pull requests, audit notes, or follow-up security work.
+
+## When to use
+
+Use this skill when you need to:
+
+- perform a broad application security review of a repository or PR diff
+- inspect changed files first, then expand to adjacent code paths and trust boundaries
+- identify security weaknesses in implementation details, configuration, or operational safeguards
+- produce prioritized findings with remediation and verification guidance
+- summarize what appears strong, what appears risky, and what remains unknown
+
+## Inputs to collect
+
+- repository, folder, or PR diff in scope
+- deployable or component type such as API, UI, worker, CLI, infrastructure scripts, or shared library
+- deployment and exposure assumptions such as public, partner-reachable, internal-only, admin-only, or multi-tenant
+- sensitive data categories such as auth/session data, PII, secrets, payments, regulated data, or internal-only data
+- known constraints such as audit requirements, incidents, abuse cases, platform boundaries, or already-known CVEs
+- repository evidence from source code, configuration, manifests, IaC, tests, docs, and route or handler declarations
+
+## How to use
+
+1. Review the current repository and current PR diff, if available, before relying on operator answers.
+2. Prioritize changed files first when a PR diff is available, then expand to surrounding code paths, shared utilities, and sensitive sinks.
+3. Use evidence first and cite file paths and, when possible, line ranges.
+4. Mark anything that cannot be confirmed from repository evidence as `ASSUMPTION` or `UNKNOWN`.
+5. Ask focused intake questions only when they materially change exposure, trust-boundary interpretation, or prioritization.
+6. Do not generate code changes unless explicitly requested.
+7. If the environment supports writing files, persist the output as a root-level Markdown file named `Secure Code Review - YYYY-MM-DD.md`.
+
+## Rules
+
+- MUST start from a fresh review of the repository or PR diff in scope.
+- MUST prioritize changed files first when a PR diff is available.
+- MUST use this evidence hierarchy for factual claims: repo-confirmed, operator-stated, `ASSUMPTION`, `UNKNOWN`.
+- MUST keep confirmed facts separate from inference.
+- MUST review project structure, entry points, trust boundaries, sensitive assets, and sensitive sinks before finalizing findings.
+- MUST explicitly assess the following areas when relevant to the codebase:
+  - input validation and injection risk
+  - authentication and authorization
+  - secrets, configuration, and environment-specific behavior
+  - logging, redaction, telemetry, and error handling
+  - crypto and token handling
+  - deserialization, file handling, upload paths, and path safety
+  - SSRF and outbound network calls
+  - dependency and supply-chain exposure
+- MUST include at least 3 code-anchored findings or clearly state why fewer were justified by the repository evidence.
+- MUST include strengths, prioritized findings, code quality notes, a remediation plan, and follow-up validation guidance.
+- MUST include actionable verification steps for each material finding.
+- MUST avoid recommending disabling security controls as the primary remediation.
+- SHOULD trace important flows as `input → validation → authorization → sink`.
+- SHOULD call out contradictions between repository evidence and operator statements before finalizing prioritization.
+- MAY proceed with explicit `ASSUMPTION` and `UNKNOWN` markers when deployment context is incomplete.
+
+## Step-by-step process
+
+### 1. Triage scope and exposure
+
+- Identify the in-scope application surface, deployables, entry points, and adjacent shared code.
+- Classify likely exposure first: public, partner-reachable, mixed, internal-only, or admin-only.
+- Capture repo-confirmed versus operator-stated deployment details separately.
+
+### 2. Map the project
+
+- Identify the major files, folders, and subsystems in scope.
+- Briefly describe the likely purpose of each major area.
+- Identify entry points, trust boundaries, sensitive assets, and sensitive sinks.
+- Note where privileged actions or high-consequence workflows appear.
+
+### 3. Identify key subsystems and high-risk flows
+
+Group the code into functional domains such as:
+
+- request routing and controllers
+- authentication and authorization
+- input parsing and validation
+- business logic
+- persistence and query layers
+- configuration and secret loading
+- logging, telemetry, and error handling
+- file handling, parsing, and deserialization
+- outbound integrations, webhooks, and HTTP clients
+- crypto, token, or session handling
+
+For each subsystem:
+
+- summarize what it does
+- identify its trust boundaries
+- explain why it is or is not high-risk
+- trace at least the most important flows as `input → validation → authorization → sink` where possible
+
+### 4. Review high-risk classes
+
+Look for:
+
+- injection risk such as SQL, NoSQL, LDAP, OS command, or template injection
+- weak validation, implicit type coercion, and parser ambiguity
+- missing or inconsistent authn/authz checks
+- broken object-level authorization, tenant isolation gaps, or confused deputy patterns
+- hardcoded secrets, dangerous defaults, or insecure environment-dependent behavior
+- logging of tokens, credentials, cookies, headers, bodies, or PII
+- verbose errors or telemetry that leak sensitive context
+- weak randomness, insecure crypto, or token validation mistakes
+- unsafe deserialization, path traversal, archive extraction risk, or upload abuse
+- user-controlled outbound requests, weak webhook validation, or SSRF paths
+- risky dependency usage, unsafe scripts, or supply-chain exposure
+
+### 5. Capture strengths and code quality issues
+
+Call out meaningful strengths such as:
+
+- centralized validation
+- consistent authorization guards
+- safe parameterization
+- structured redaction
+- strong secret handling
+- environment-aware hardening
+- clear privilege separation
+
+Also note maintainability issues that materially affect security posture, such as duplicated auth logic, inconsistent validation, brittle config loading, or scattered logging behavior.
+
+### 6. Prioritize findings
+
+Focus on findings that are:
+
+- grounded in actual repository evidence
+- realistic in impact and exploitability
+- specific enough for an engineer to fix
+- useful to a pull request reviewer or security owner
+
+For each material finding, include:
+
+- **Title**
+- **Severity**: Critical / High / Medium / Low / Informational
+- **Confidence**: High / Medium / Low
+- **Category**
+- **Where**
+- **Risk**
+- **Impact**
+- **Evidence**
+- **Recommendation**
+- **Verification**
+
+Where useful, also include:
+
+- **Prerequisites**
+- **Reproduction path**
+- **Compensating controls**
+- **Why this may be safer in practice**
+
+### 7. Close with a remediation plan
+
+Organize next steps into:
+
+- **Quick wins (hours)**
+- **Medium fixes (days)**
+- **Structural guardrails (weeks)**
+
+Examples of structural guardrails:
+
+- shared validation helpers
+- centralized authorization policy checks
+- redaction middleware
+- safer outbound request wrappers
+- secret scanning
+- security-focused tests
+- CI linting or SAST rules for recurring patterns
+
+## Output format
+
+Produce PR-comment-ready Markdown in chat.
+
+If the environment supports writing files, also write:
+
+`./Secure Code Review - YYYY-MM-DD.md`
+
+The report MUST include these sections:
+
+1. Executive summary
+2. Scope and assumptions
+3. Strengths
+4. Prioritized findings
+5. Code quality notes
+6. Remediation plan
+7. Suggested follow-up validation
+8. Open questions
+
+### Executive summary
+
+- 5-10 bullets
+- what was reviewed
+- what appears strong
+- what appears risky
+- major unknowns
+- immediate next actions
+
+### Scope and assumptions
+
+Include:
+
+- in-scope components
+- out-of-scope components if relevant
+- PR diff reviewed or not reviewed
+- deployment assumptions
+- sensitive data or trust boundaries
+- evidence limitations
+- `ASSUMPTION` and `UNKNOWN` items that materially affect risk interpretation
+
+### Strengths
+
+Use bullets tied to repository evidence.
+
+### Prioritized findings
+
+Repeat this structure for each material finding:
+
+- **Title**
+- **Severity**
+- **Confidence**
+- **Category**
+- **Where**
+- **Risk**
+- **Impact**
+- **Evidence**
+- **Recommendation**
+- **Verification**
+
+### Code quality notes
+
+Capture non-vulnerability issues that materially affect security posture.
+
+### Remediation plan
+
+Split into:
+
+- quick wins
+- medium fixes
+- structural guardrails
+
+### Suggested follow-up validation
+
+Include targeted tests, abuse-case checks, log review, authz regression coverage, dependency review, or secret scanning as appropriate.
+
+### Open questions
+
+List unresolved questions with likely owner or location to confirm.
+
+## Quality checks
+
+- findings are grounded in repository evidence rather than generic advice
+- changed files were prioritized when a PR diff was available
+- strengths and weaknesses are both covered
+- each finding includes `Where` and `Evidence`
+- severity is proportionate to exploitability and impact
+- verification steps are actionable
+- logging/redaction, secrets/config, access control, and environment-specific behavior were explicitly considered
+- evidence and inference are clearly separated

+# Robotti Developer Agent
+
+This document defines how the you *(the agent)* should behave while working in this repository.
+
+The hard global rules live in `copilot-instructions.md`.
+That file is the constitution.
+This file focuses on behavior, workflow, and decision-making inside those constraints.
+
+## Mission
+
+You are an AI engineering partner operating in a plan-driven development workflow for secure JavaScript web applications.
+
+Your job is to help plan, implement, review, and refine changes that are:
+
+- small
+- testable
+- auditable
+- aligned with the repository's existing architecture
+- compliant with the constitution in `copilot-instructions.md`
+
+## Operating Principles
+
+1. Preserve existing seams.
+   - Follow the repository's current boundaries and ownership model.
+   - Adapt to the repo's seam pattern instead of forcing a new architecture.
+2. Prefer small, reviewable diffs.
+   - Make the minimum coherent change needed.
+   - Avoid broad refactors unless explicitly approved.
+3. Be explicit.
+   - Use straightforward JavaScript.
+   - Prefer simple modules, clear names, and inspectable control flow.
+   - Avoid hidden magic and unnecessary abstraction.
+4. Stop on risky ambiguity.
+   - Do not guess on auth, persistence, deployment, logging, security posture, public contracts, or execution environment.
+   - Surface the issue and ask for approval when a protected boundary is involved.
+5. Treat the constitution as binding.
+   - Preserve the language, validation, logging, CSP, execution, and deployment rules from `copilot-instructions.md`.
+   - Do not optimize around them or quietly weaken them.
+
+## Architecture Behavior
+
+### Backend
+
+- Keep routes focused on HTTP concerns.
+- Keep controllers request-focused when the repo uses controllers.
+- Put reusable business, persistence, and integration logic in helpers, services, or utilities consistent with the repo.
+- Preserve centralized config, validation, logging, and error handling.
+- Preserve middleware ordering and infrastructure-level security controls.
+
+### Frontend
+
+- Keep route-level composition readable and local.
+- Prefer small components, focused hooks, and shared utilities when reuse is justified.
+- Use existing API helper patterns when present.
+- Avoid introducing a new client-side abstraction layer unless clearly needed and approved.
+
+## Planning Behavior
+
+When asked to plan:
+
+- inspect the feature doc and codebase first
+- identify impacted modules, trust boundaries, and approval-gated changes
+- produce a small, sequenced implementation plan
+- surface assumptions, risks, and open questions
+- stop before coding
+
+## Implementation Behavior
+
+When asked to implement:
+
+- implement one approved task at a time
+- stay tightly scoped
+- preserve existing repo conventions
+- preserve the constitutional requirements for validation, logging, security headers, execution rules, and deployment compatibility
+- prefer repository-defined scripts for validation and local workflows
+- check `package.json` before running lint, test, build, or dev commands
+- detect the execution environment before running OS-specific commands
+- add or update tests for behavior changes
+- report blockers or drift instead of silently expanding scope
+
+## Review Behavior
+
+When reviewing a plan or implementation, check for:
+
+- scope creep
+- drift from repo conventions
+- missing validation
+- missing required logs
+- weakened security posture
+- unapproved auth, persistence, API, or deployment changes
+- unsafe execution assumptions
+- missing tests
+- avoidable complexity
+
+## Approval Gates
+
+Pause and ask before making changes to:
+
+- authentication or authorization
+- tokens, sessions, cookies, or admin access
+- persistence model or storage schema
+- public API contracts
+- telemetry, analytics, or PII collection
+- logging schema or redaction behavior
+- CSP or other security header policy
+- CI/CD, containerization, or deployment behavior
+- new third-party services or major dependencies
+- broad architectural refactors
+
+## Definition Of Aligned Work
+
+Work is aligned when it:
+
+- follows repository structure and module roles
+- uses JavaScript and existing stack conventions
+- stays inside the constitutional guardrails
+- keeps changes small and reviewable
+- preserves secure defaults
+- remains test-backed and deployable

+name: implement-feat
+description: Implement a single approved task from a feature document's implementation plan. Scoped execution only; no silent plan expansion.
+---
+
+# /implement-feat
+
+## Purpose
+
+Use this skill when the user already has a feature document with an approved implementation plan and wants to execute one task from that plan.
+
+This skill:
+
+- reads the feature document and implementation plan
+- identifies the requested task
+- implements only that task
+- keeps changes tightly scoped
+- updates tests as required for that task
+- reports what changed, what was validated, and any blockers or deviations
+
+This skill is for **execution of one approved task at a time**.
+
+---
+
+## When to Use
+
+Use this skill when the user asks to:
+
+- implement a specific task from a feature plan
+- execute the next approved step in a feature document
+- complete one bounded slice of the implementation
+- make code changes tied to a named task ID
+
+Good fits:
+
+- “Implement T2 from the feature plan.”
+- “Complete the next approved task in this doc.”
+- “Build task T4 and update tests.”
+- “Execute the first pending task.”
+
+---
+
+## When Not to Use
+
+Do **not** use this skill when the user wants:
+
+- a new implementation plan
+- broad feature analysis before planning
+- multi-feature execution across unrelated docs
+- speculative refactoring
+- unbounded “implement the whole feature” behavior without task scope
+
+If the feature does not yet have an implementation plan, use `/plan-feat` first.
+
+---
+
+## Inputs
+
+Expected inputs:
+
+- path to the feature document
+- task ID to implement, or a clear instruction like “next approved task”
+- access to the repository / workspace
+
+Optional inputs:
+
+- additional constraints
+- explicit approval notes
+- preferred validation depth
+
+If the task ID is not provided but “next approved task” is requested, infer the next task from the documented task order and status, if available.
+
+---
+
+## Core Rules
+
+1. **Implement one task only**
+   - Do not work on multiple tasks unless explicitly instructed.
+   - Do not silently pull in later tasks.
+
+2. **Respect the approved plan**
+   - The implementation plan is the source of execution scope.
+   - If reality contradicts the plan, stop and flag the drift.
+
+3. **Stay tightly scoped**
+   - Make the smallest coherent set of changes needed for the selected task.
+   - Avoid opportunistic cleanup or unrelated refactors.
+
+4. **Follow project conventions**
+   - Use existing code patterns, naming, architecture, and testing style.
+
+5. **Update validation with code**
+   - Add or update tests, checks, or validations required by the task.
+
+6. **Stop on material ambiguity**
+   - If the task depends on unresolved assumptions, missing prerequisites, or plan errors, stop and report rather than guessing.
+
+7. **Be explicit about deviations**
+   - If a small deviation from the plan is necessary, explain it clearly.
+   - Do not silently redefine the task.
+
+---
+
+## Workflow
+
+Follow this sequence:
+
+### 1. Read the Feature Document and Plan
+
+Review:
+
+- feature intent
+- implementation plan
+- task breakdown
+- execution order
+- dependencies
+- open questions / assumptions
+- any task status markers if present
+
+Identify the selected task and its exact scope.
+
+### 2. Confirm Task Boundaries
+
+Determine:
+
+- what this task is supposed to accomplish
+- what files or modules are likely in scope
+- what is explicitly out of scope
+- what prerequisites must already be satisfied
+
+If the task depends on unfinished earlier work, stop and report it.
+
+### 3. Inspect Relevant Code
+
+Look at the code directly related to the task:
+
+- implementation points
+- adjacent interfaces
+- tests
+- config
+- schema / migration code
+- docs if affected
+
+Ground the work in existing project patterns.
+
+### 4. Implement the Task
+
+Make only the changes required to satisfy the selected task’s objective and definition of done.
+
+Keep the implementation:
+
+- minimal
+- coherent
+- reviewable
+- consistent with the codebase
+
+### 5. Add or Update Validation
+
+Update tests or validation steps required for the task, such as:
+
+- unit tests
+- integration tests
+- API tests
+- UI tests
+- schema validations
+- type checks
+- linting or build-related adjustments when needed
+
+Do not claim validation that was not actually performed.
+
+### 6. Update Task Status if Appropriate
+
+If the workflow uses status markers in the feature doc, update the selected task accordingly.
+
+Examples:
+
+- pending → in progress
+- in progress → done
+
+Only update status if the task’s definition of done is actually satisfied.
+
+### 7. Summarize Outcome
+
+Provide a concise implementation summary including:
+
+- what changed
+- why it changed
+- tests or validation performed
+- anything that needs review
+- any blockers, deviations, or follow-up needed
+
+---
+
+## Scope Controls
+
+Treat the following as out of scope unless explicitly required by the selected task:
+
+- unrelated refactors
+- style-only cleanup across unrelated files
+- dependency upgrades
+- architecture redesign
+- renaming campaigns
+- fixing nearby unrelated bugs
+- implementing future plan tasks
+
+If you encounter a tempting improvement outside scope, note it separately rather than including it in the change.
+
+---
+
+## Drift Handling
+
+Stop and report instead of proceeding when:
+
+- the task is ambiguous
+- the codebase reality conflicts with the plan
+- a required prerequisite task is unfinished
+- the requested task actually spans multiple tasks
+- new schema / API / architectural work appears necessary but was not planned
+- the feature doc lacks enough detail to safely continue
+
+When reporting drift, include:
+
+- what was expected
+- what was found
+- why it matters
+- the smallest decision needed from the user
+
+---
+
+## Required Response Structure
+
+After implementation, provide a concise summary in this shape:
+
+```markdown
+## Task Implementation Summary
+
+### Task
+- Task ID:
+- Title:
+
+### What Changed
+- Concise list of code changes made
+
+### Validation
+- Tests added or updated
+- Checks performed
+- Anything not validated
+
+### Notes for Review
+- Important tradeoffs
+- Small deviations from plan
+- Follow-up considerations
+
+### Status
+- Completed / Blocked / Partial
+
+### Blockers (if any)
+- What prevented completion
+- What decision or prerequisite is needed
+```
+
+If the task is blocked, do not pretend partial completion equals success.
+
+---
+
+## Decision Heuristics
+
+When implementing, prefer:
+
+- minimal diffs over broad rewrites
+- explicit logic over cleverness
+- local consistency over abstract purity
+- task completion over incidental optimization
+- code the team can maintain over code that merely looks sophisticated
+
+Ask internally:
+
+- Is this change strictly required for the selected task?
+- Am I pulling in future work?
+- Am I preserving current conventions?
+- Did I update validation appropriately?
+- Did I encounter uncertainty that should stop execution?
+
+---
+
+## Failure Modes to Avoid
+
+Do not:
+
+- implement the whole feature at once
+- broaden scope because adjacent changes seem easy
+- ignore the approved plan
+- skip tests when the task requires them
+- silently change architecture
+- mark a task done without satisfying its definition of done
+- conceal blockers behind partial implementation language
+
+---
+
+## Completion Check
+
+Before finishing, verify that you:
+
+- implemented only the selected task
+- stayed aligned with the approved plan
+- kept changes scoped and reviewable
+- updated validation appropriately
+- updated task status only if warranted
+- clearly reported blockers or deviations
+- did not silently expand scope

+name: plan-feat
+description: Analyze a feature document and the current codebase, then append a concrete implementation plan with small actionable tasks. Planning only; no coding.
+---
+
+# /plan-feat
+
+## Purpose
+
+Use this skill when the user has a feature document that describes a feature at a high level and wants an implementation plan before coding begins.
+
+This skill converts intent into an auditable implementation plan by:
+
+- reading the feature document
+- analyzing the repository and relevant code paths
+- identifying impacted systems and files
+- proposing an implementation approach aligned with the existing architecture
+- breaking the work into small, sequenced, actionable tasks
+- appending the plan back into the feature document
+
+This skill is **planning only**. It must **not** implement code.
+
+---
+
+## When to Use
+
+Use this skill when the user asks to:
+
+- create an implementation plan for a feature
+- review a feature doc and determine how to build it
+- break a feature into tasks before implementation
+- analyze the project and append a plan to the feature doc
+- prepare work for plan-driven development
+
+Good fits:
+
+- “Review this feature doc and generate a plan.”
+- “Analyze the codebase and add an implementation plan.”
+- “Break this feature into small actionable tasks.”
+- “Figure out how this should be implemented in this repo.”
+
+---
+
+## When Not to Use
+
+Do **not** use this skill when the user wants:
+
+- direct implementation now
+- debugging of an already-started task
+- review of completed code changes
+- a generic brainstorming session with no feature artifact
+- a roadmap across many unrelated features
+
+If the user is asking to build an approved task from an existing plan, use `/implement-feat` instead.
+
+---
+
+## Inputs
+
+Expected inputs:
+
+- path to a feature document
+- access to the current repository / workspace
+- optionally:
+  - constraints
+  - preferred architecture direction
+  - task size preference
+  - known open questions
+
+If some of these are missing, proceed with best-effort analysis and surface assumptions explicitly.
+
+---
+
+## Core Rules
+
+1. **Do not implement code**
+   - This skill stops at planning.
+   - No code edits, no partial implementation, no opportunistic refactors.
+
+2. **Analyze before proposing**
+   - Read the feature document first.
+   - Inspect the relevant codebase areas before producing a plan.
+
+3. **Prefer existing patterns**
+   - Follow the current architecture, conventions, naming, layering, and testing style.
+   - Do not invent new abstractions unless there is a strong codebase-driven reason.
+
+4. **Surface uncertainty**
+   - Do not silently guess about project-specific behavior.
+   - Capture assumptions and open questions clearly.
+
+5. **Keep tasks small**
+   - Tasks should be reviewable, bounded, and meaningfully sequential.
+   - Avoid giant “implement everything” tasks.
+
+6. **Plan for validation**
+   - Each task should include expected tests, checks, or validation steps.
+
+7. **Include non-code concerns where relevant**
+   - Migrations
+   - configuration
+   - data model changes
+   - API contracts
+   - UI states
+   - performance
+   - security
+   - backward compatibility
+   - rollout concerns
+   - documentation updates
+
+8. **Respect conflicts**
+   - If the feature doc conflicts with the codebase, note the conflict.
+   - Do not force a plan around a contradiction.
+
+---
+
+## Workflow
+
+Follow this sequence:
+
+### 1. Read the Feature Document
+
+Understand:
+
+- the high-level goal
+- intended user or system outcome
+- stated requirements
+- implicit assumptions
+- undefined or ambiguous areas
+
+Create a concise internal summary before analyzing the repo.
+
+### 2. Inspect the Relevant Codebase
+
+Review the code paths most likely to be involved, such as:
+
+- existing feature-adjacent modules
+- domain models
+- services
+- controllers / routes / APIs
+- UI components
+- data access layers
+- jobs / workers / queues
+- tests
+- configuration
+- schema / migration layers
+- docs if they define existing behavior
+
+Infer how the feature fits the current architecture.
+
+### 3. Identify Implementation Shape
+
+Determine:
+
+- where changes should live
+- what layers are affected
+- which existing abstractions should be reused
+- what sequence of changes makes the work safest
+- where validation should happen
+- what dependencies or blockers exist
+
+### 4. Create Small Actionable Tasks
+
+Break the work into ordered tasks.
+
+Each task should include:
+
+- Task ID
+- Title
+- Objective
+- Specific changes to make
+- Definition of done
+- Expected tests / validation
+
+Tasks should be:
+
+- small
+- explicit
+- scoped
+- sequenced
+- reviewable
+
+### 5. Capture Risks and Open Questions
+
+Explicitly list:
+
+- assumptions
+- unanswered questions
+- design tradeoffs
+- technical risks
+- edge cases
+- rollout or compatibility concerns
+
+### 6. Append the Plan to the Feature Document
+
+Append the implementation plan into the feature document under the exact heading:
+
+```markdown
+## Implementation Plan
+```
+
+If the heading already exists, update or replace the existing implementation plan section instead of duplicating it.
+
+---
+
+## Required Output Structure
+
+Append this structure to the feature document:
+
+```markdown
+## Implementation Plan
+
+### 1. Feature Summary
+- Concise restatement of the feature and intended outcome
+
+### 2. Relevant Existing Architecture
+- Key modules, services, components, data models, APIs, and patterns involved
+
+### 3. Proposed Approach
+- Recommended implementation approach
+- Why this approach fits the current codebase
+
+### 4. Impacted Areas
+- Files, modules, components, routes, schemas, migrations, tests, configs, docs
+
+### 5. Task Breakdown
+
+#### T1: <task title>
+- Objective:
+- Specific changes:
+- Definition of done:
+- Expected tests / validation:
+
+#### T2: <task title>
+- Objective:
+- Specific changes:
+- Definition of done:
+- Expected tests / validation:
+
+<!-- Continue as needed -->
+
+### 6. Risks and Edge Cases
+- Technical risks
+- Product / UX edge cases
+- Operational concerns
+- Backward compatibility concerns
+
+### 7. Open Questions / Assumptions
+- Items requiring user confirmation
+- Assumptions made from incomplete information
+
+### 8. Suggested Execution Order
+1. T1 - reason
+2. T2 - reason
+3. T3 - reason
+```
+
+---
+
+## Task Sizing Guidance
+
+Prefer tasks that represent one meaningful unit of change, such as:
+
+- add or update a domain model
+- adjust one service flow
+- add one API change
+- add one UI integration slice
+- add or update one test layer
+- perform one migration or config update
+
+Avoid combining multiple unrelated layers into one task unless the repository structure makes separation artificial.
+
+If a task feels large, split it.
+
+---
+
+## Decision Heuristics
+
+When planning, prefer:
+
+- existing abstractions over new frameworks
+- minimal viable design changes over speculative redesign
+- explicit seams over hidden magic
+- codebase consistency over elegance in isolation
+- safer sequencing over parallel complexity
+
+Ask internally:
+
+- What is already here that should be reused?
+- What is the smallest safe path to shipping this?
+- What must be true before later tasks can happen?
+- Where is the highest risk concentrated?
+- What assumptions am I making that the user should review?
+
+---
+
+## Failure Modes to Avoid
+
+Do not:
+
+- start coding
+- generate a vague plan with oversized tasks
+- ignore tests
+- omit operational or migration concerns when relevant
+- assume requirements that are not in the doc or codebase
+- produce generic advice detached from the repository
+- recommend broad refactors without justification
+
+---
+
+## Completion Check
+
+Before finishing, verify the plan is:
+
+- grounded in the current repository
+- aligned with existing architecture
+- broken into small tasks
+- explicit about assumptions
+- reviewable by a human
+- appended to the feature document
+- planning-only, with no implementation performed

 ### Steps
 
-1. Map the project (entry points, trust boundaries, sensitive assets).
-   - List all visible files and folders.
-   - For each, briefly describe its purpose or domain (e.g., "core logic," "auth," "logging utilities").
-2. Identify key subsystems/domains and their responsibilities.
-   - Identify the key **subsystems or functional domains** in this project.
-   - Explain what role each plays (e.g., request routing, encryption, config parsing).
-3. Review by subsystem, focusing on high-risk classes:
-   - input validation, authn/authz, secrets/logging, crypto, deserialization, SSRF, dependency risks.

 # Secure Code Review
 
+## Purpose
+
+Provide a repeatable, evidence-first application security review workflow for a repository or PR diff.
+
 ## When to use
 
-Use this skill when asked to **review code for security**, produce findings, or prepare guidance for remediation.
+Use this skill when you need to:
+
+- review code for security issues
+- assess a repository or PR diff for application security risk
+- produce prioritized findings and fix guidance
+- identify trust boundaries, sensitive data flows, and risky implementation patterns
+
+## Inputs to collect
+
+- repository, folder, or PR diff in scope
+- component type such as API, UI, worker, CLI, infrastructure scripts, or shared library
+- data sensitivity such as auth/session data, PII, payments, secrets, or internal-only data
+- deployment assumptions such as internet-facing, internal-only, admin-only, or multi-tenant
+- known incidents, audit requirements, abuse cases, or CVEs, if available
+
+## How to use
 
-## Inputs to collect (if available)
+1. Start from a fresh read of the current workspace and current PR diff, if available.
+2. Prioritize changed files first when a PR diff is available, then expand repo-wide where needed.
+3. Prefer evidence-first analysis and cite file paths and, when possible, line ranges.
+4. Keep confirmed evidence separate from inference, and label uncertainty as `ASSUMPTION` or `UNKNOWN`.
+5. Do not modify files unless explicitly asked.
+6. If the environment supports writing files, persist the output as a root-level Markdown file named `Secure Code Review - YYYY-MM-DD.md`.
 
-- What component(s) are in scope (API, UI, worker, infra scripts)
-- Data sensitivity (PII, auth/session, payments)
-- Deployment assumptions (internet-facing, internal, multi-tenant)
-- Any known incidents, CVEs, or audit requirements
+## Rules
+
+- MUST begin with a fresh review of the repository or PR diff in scope.
+- MUST prioritize changed files first when a PR diff is available.
+- MUST keep findings tied to repository evidence such as source code, config, manifests, IaC, docs, and tests.
+- MUST distinguish confirmed evidence from `ASSUMPTION` and `UNKNOWN`.
+- MUST review project structure, entry points, trust boundaries, sensitive assets, and sensitive sinks before finalizing findings.
+- MUST explicitly assess at least these areas when relevant to the codebase:
+  - input validation and injection risk
+  - authentication and authorization
+  - secrets, configuration, and environment-specific behavior
+  - logging, redaction, and error handling
+  - crypto and token handling
+  - deserialization, file handling, and path safety
+  - SSRF and outbound network calls
+  - dependency and supply-chain exposure
+- MUST include strengths, prioritized findings, code quality notes, and a remediation plan.
+- MUST include actionable verification steps for each material finding.
+- MUST avoid recommending weaker "turn it off" style mitigations as the primary fix.
+- SHOULD trace important flows as `input → validation → authorization → sink`.
+- SHOULD prefer concise code excerpts or logic summaries over long pasted snippets.
+- MAY continue with explicit `ASSUMPTION` and `UNKNOWN` markers when deployment context is missing.
 
 ## Step-by-step process
 
-1. **Map entry points & trust boundaries**
-   - Enumerate request handlers, background consumers, file parsers, template renderers, and admin endpoints.
-   - Identify where untrusted input crosses into privileged actions or sensitive sinks.
-2. **Scan for high-risk classes**
-   - Injection: SQL/NoSQL/LDAP/OS/template
-   - Authn/authz: missing checks, insecure defaults, confused deputy
-   - Deserialization & file handling: unsafe loads, path traversal, upload
-   - Crypto: homegrown crypto, weak randomness, token validation mistakes
-   - Logging: secrets/PII exposure, overly verbose errors
-   - SSRF: URL fetchers, webhook validation gaps
-3. **Deep-dive the highest impact areas**
-   - Trace data flow from input → validation → authorization → sink.
-   - Look for missing allow-lists, type confusion, and implicit conversions.
-4. **Write findings in a consistent format**
-   - Title, severity, confidence
-   - Where (file/function)
-   - Risk + prerequisites
-   - Repro steps
-   - Recommendation + verification steps
-5. **Close with a remediation plan**
-   - Quick wins (hours), medium fixes (days), structural guardrails (weeks).

-### Summary
-
-- Scope reviewed:
-- Top issues:
-- Overall risk: Low / Medium / High / Critical
-
-### Findings (repeat)
+1. **Map the project**
+   - Identify the major files, folders, and subsystems in scope.
+   - Describe the likely purpose of each major area.
+   - Identify entry points, trust boundaries, sensitive assets, and sensitive sinks.
+2. **Identify key subsystems**
+   - Group the code into functional domains such as routing, auth, validation, business logic, persistence, config, logging, integrations, and crypto/session handling.
+   - For each subsystem, explain what it does, why it is or is not high-risk, and where trust boundaries appear.
+3. **Review high-risk classes**
+   - Injection, unsafe parsing, and type confusion
+   - Authn/authz failures and insecure defaults
+   - Secrets exposure and dangerous configuration behavior
+   - Sensitive logging, missing redaction, and verbose error handling
+   - Weak randomness, insecure hashing, or token validation mistakes

+   - Risky dependency usage or supply-chain patterns
+4. **Deep-dive the highest impact flows**
+   - Trace important flows from input to validation to authorization to sensitive action.
+   - Look for checks performed too late, inconsistent enforcement, hidden alternate paths, or controls applied in one path but missing in another.
+5. **Write prioritized findings**
+   - Focus on security-relevant, evidence-grounded findings with realistic impact and exploitability.
+   - Also call out meaningful strengths and code quality issues that materially affect security posture.
+6. **Close with a remediation plan**
+   - Organize recommendations into quick wins, medium fixes, and structural guardrails.
