The create→save→run flow was broken end to end: a workflow could be
rendered to Mermaid but never parsed back, the visual builder's
Save/Load/Run buttons were no-op stubs, and a saved .mmd chart could
not be validated or executed.

  • Add graph.ParseMermaid: a Mermaid (graph/flowchart) -> DAG parser so a
    .mmd chart authored by hand or saved by the builder becomes a
    first-class, runnable input. Edge labels stay labels (only genuine
    conditions become Edge.Condition) so a decorative label like
    "sequential" no longer causes RunDAG to skip every downstream node.
  • Add tui.LoadWorkflowAny: format-aware loading (.mmd via ParseMermaid
    with catalog-based tool/arg hydration, otherwise JSON). Route run,
    validate, and preview (CLI + menu) through it; preview now parses and
    re-renders a .mmd instead of echoing it unparsed.
  • Wire the builder's header buttons: Save writes workflow.json +
    workflow.mmd, Load reopens them, Run saves and executes against the
    entered domain, and esc/q returns to the menu.
  • Fix latent crashes on the run path: the extensionless parseOutputFile
    slice-bounds panic, the empty template-picker nil type assertion, and
    Preview being gated on the wrong file.
  • Regenerate a consistent, runnable workflow.mmd; drop broken auto-save
    cruft from workflows/; refresh the README menu list and CLI docs.
  • Tests: Mermaid parser unit tests, an end-to-end .mmd -> RunDAG
    execution test (via echo), and a builder save/load round-trip.

Reviewer's Guide

Adds a Mermaid-to-DAG parser and a format-aware workflow loader so .mmd charts become first-class runnable workflows across CLI and TUI, wires up the visual builder’s Save/Load/Run header buttons to persist and execute workflows, fixes several run-path crashes, and updates docs, sample workflows, and tests to cover the new Mermaid-based flow.

File-Level Changes

Change Details Files
Introduce a lenient Mermaid graph/flowchart parser that turns .mmd charts into executable DAGs and validates their structure.
  • Add internal/graph/parse.go implementing ParseMermaid and a mermaidParser that tokenizes lines, parses nodes, edges, subgraphs, and assigns layers/positions.
  • Ensure decorative edge labels stay as labels while only whitelisted expressions become Edge.Condition to avoid gating on cosmetic labels.
  • Auto-attach orphan nodes to the implicit root and derive deterministic matrix coordinates so parsed graphs pass Validate and ValidateMatrix.
  • Skip styling and unknown lines, handle HTML entities and label line breaks, and treat layer-wrapper subgraphs specially.
internal/graph/parse.go
Add comprehensive tests for the Mermaid parser, Mermaid workflow loading, and builder save/load round-trips.
  • Create internal/graph/parse_test.go to cover node shape kinds, chained edges, id/args parsing, label vs condition behavior, subgraph handling, layer assignment, error cases, and ToMermaid round-trips.
  • Add internal/tui/mermaidload_test.go to verify LoadWorkflowAny hydrates Mermaid nodes from the catalog, runs a simple echo-based chart end to end through RunDAG, and leaves JSON workflows unchanged.
  • Add internal/tui/builder_test.go to exercise builder.saveWorkflow/loadWorkflow, validate both JSON and .mmd artifacts, and ensure the occurrence counter is rebuilt correctly.
internal/graph/parse_test.go
internal/tui/mermaidload_test.go
internal/tui/builder_test.go
Introduce a unified workflow loader that supports both JSON and Mermaid files and hydrates Mermaid graphs from the tool catalog.
  • Add LoadWorkflowAny in internal/tui/workflowio.go to dispatch between JSON (LoadWorkflowV3) and Mermaid (graph.ParseMermaid) based on extension, with error wrapping.
  • Implement hydrateFromCatalog plus helpers stripToolSuffix and suffixNumber to infer Tool/Args from node IDs and catalog defaults for Mermaid-based DAGs.
  • Refactor run/validate/preview code paths (headless, menu, builder run) to use LoadWorkflowAny so .mmd charts are first-class everywhere.
internal/tui/workflowio.go
internal/tui/headless.go
internal/tui/menu.go
Wire the TUI workflow builder header buttons to real save/load/run behavior and improve navigation semantics.
  • Extend BuilderModel.Update to route mouse and keyboard events through new handleAction/activateButton helpers before generic key handling.
  • Implement handleAction to handle esc/q/ctrl+c, header focus switching, and enter-based button activation with model handoff (e.g., to menu or run view).
  • Implement activateButton, saveWorkflow, loadWorkflow, and rebuildOcc: Save writes workflow.json + workflow.mmd, Load reopens them (preferring JSON), and Run saves then launches runWorkflowWithDomain.
  • Update help text and remove unused ANSI-stripping logic now that header clicks are handled differently.
internal/tui/builder.go
Enhance the TUI menu/template picker and CLI to understand Mermaid workflows and surface better preview/template behavior.
  • Add templateFiles helper to collect both .json and .mmd templates, sorted, and update MenuModel to use it for template count and template picker inputs.
  • Change preview behavior to look for either workflow.json or workflow.mmd and show a clearer error when neither exists, and make MermaidForWorkflow parse + re-render .mmd files when possible.
  • Harden tmplPicker.Update against an empty list by guarding SelectedItem casts and returning to the menu when no templates exist.
internal/tui/menu.go
internal/tui/headless.go
internal/tui/tmplpicker.go
Allow CLI run/validate subcommands and pipeline output parsing to support both JSON and Mermaid workflows and avoid panics.
  • Update cmd/termaid/main.go flag help text for -w on run/validate subcommands to mention Mermaid .mmd support.
  • Switch RunHeadlessWithOptions and ValidateWorkflow to load via LoadWorkflowAny so .mmd paths work in headless mode too.
  • Fix parseOutputFile in internal/pipeline/pipeline.go to guard against paths with no file extension, avoiding a slice-bounds panic.
cmd/termaid/main.go
internal/tui/headless.go
internal/pipeline/pipeline.go
Refresh documentation and the sample workflow chart to reflect the new Mermaid-first authoring flow and menu options.
  • Update README main menu section, add a “Author a chart, then run it” section, and document that run/preview/validate accept both JSON and .mmd workflows.
  • Revise workflow.mmd to be a consistent, runnable example: add comments, normalize node definitions and edges, remove the L2 layer subgraph, and clean up edge labels/flows.
  • Remove stale auto-saved workflow templates under workflows/ that no longer reflect the current behavior.

Review Change Stack

Walkthrough

The change adds Mermaid workflow parsing and loading. It integrates Mermaid workflows with validation, headless execution, menu templates, and builder Save, Load, and Run actions. Documentation and the example workflow now describe and use both JSON and Mermaid formats.

Changes

Mermaid workflow support

Layer / File(s) Summary
Mermaid parser and DAG construction
internal/graph/parse.go, internal/graph/parse_test.go
Added lenient Mermaid parsing, node and edge handling, condition parsing, subgraph support, orphan attachment, DAG validation, layout assignment, entity decoding, and round-trip tests.
Workflow loading and execution
internal/tui/workflowio.go, internal/tui/headless.go, internal/pipeline/pipeline.go, internal/tui/mermaidload_test.go
Added format-aware loading and catalog hydration for Mermaid workflows. Validation and headless execution now use LoadWorkflowAny. Extensionless output paths no longer cause a slice panic.
Builder persistence and menu integration
internal/tui/builder.go, internal/tui/builder_test.go, internal/tui/menu.go, internal/tui/tmplpicker.go
Added builder Save, Load, and Run actions. The builder writes JSON and Mermaid files, restores loaded state, and rebuilds occurrence counters. Menus discover and run both workflow formats.
CLI, documentation, and workflow artifacts
cmd/termaid/main.go, README.md, workflow.mmd, workflows/*
Updated CLI descriptions and documentation for Mermaid support. Updated the example workflow wiring and removed obsolete generated workflow artifacts.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to e381d

The PR makes Mermaid workflows runnable, but current code can silently omit dependencies in common hand-authored syntax and the bundled workflow cannot perform its intended ffuf step, causing incorrect execution order or failed workflow runs; merge should wait for these correctness issues to be fixed or explicitly accepted.

Hey - I've found 1 issue, and left some high level feedback:

  • In MermaidForWorkflow, when Mermaid parsing fails you currently fall back to returning the raw file content without surfacing the parse error; consider including a short parse error banner or message in the preview so users immediately see that their chart is structurally invalid instead of assuming it reflects the runnable graph.
  • The logic that decides whether a path is treated as Mermaid vs JSON (extension checks for .mmd/.mermaid) is duplicated in LoadWorkflowAny and MermaidForWorkflow; consider centralizing this in a small helper (e.g. isMermaidPath) to avoid extension-handling drift between load and preview paths.

Reuse the existing index when a node is already attached to the subgraph.

attachSubgraph always sets n.SubX = len(sg.Nodes) - 1. If the node is already in sg.Nodes, this assigns the index of the last appended node instead of the node's own index. A second mention of the same node inside the same subgraph (for example a node definition line and then an edge line inside the subgraph) then writes a duplicate coordinate into sg.Matrix, and two nodes share one subgraph cell.

-	}
-	if n := p.g.Nodes[id]; n != nil {

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Handle labeled chains and unspaced arrows, or report the dropped edges.

Two common hand-authored forms lose edges silently:

  1. A chained line with a label, for example a -->|x| b --> c. rePipeLabel captures m[3] as b --> c, registerNode cannot parse that token, and addEdge returns without adding any edge. The same happens for a --> b -->|x| c, where m[1] is a --> b.
  2. An arrow without surrounding whitespace, for example a-->b. reLinkDetect requires whitespace around the operator, so the line falls through to reNodeToken, does not match, and is skipped.

In both cases the parse succeeds and the resulting DAG omits the dependency. attachOrphansToRoot then wires the target to the root, so the workflow runs with the wrong ordering and data flow instead of failing.

Consider scanning each edge line left to right for link operators (with optional |label| after each operator, and without requiring whitespace), then emitting one edge per adjacent token pair. If the line cannot be tokenized, record a diagnostic instead of dropping it.

Use filepath.Ext on the base name.

strings.LastIndex(filepath, ".") scans the whole path. If a directory component contains a dot and the file name does not, for example workdir/run.1/report, ext becomes .1/report. The switch then falls to the text parser by accident rather than by rule. The parameter name filepath also shadows the path/filepath package, so rename it first.

Load the newer artifact, or state the preference in the status message.

loadWorkflow uses workflow.json whenever it exists, and falls back to workflow.mmd only when the JSON file is absent. A user who edits workflow.mmd in an external editor, then presses Load, silently gets the stale JSON graph, while the status line reports "loaded workflow from disk". Include the loaded path in m.msg, and consider preferring the file with the newer modification time.

Sanitized Mermaid ids break the occurrence counter, and no test covers that path. ToMermaid rewrites subfinder-1 to subfinder_1, but the counter logic only parses a trailing -<digits>, and the round-trip test only loads the JSON artifact.

In `@internal/tui/builder.go` around lines 432 - 446, Update
internal/tui/builder.go:432-446 in BuilderModel.rebuildOcc so suffixNumber
recognizes Mermaid occurrence IDs using “_” as well as “-” separators,
preserving existing hyphen handling. Update internal/tui/builder_test.go:60-73
to remove workflow.json before calling loadWorkflow again, ensuring the
workflow.mmd fallback path and rebuilt occurrence counters are asserted.

Report the real preview error when only workflow.json exists.

The new guard passes when either file exists. previewMermaid then prefers workflow.json; if MermaidForWorkflow fails on it, the function falls through to reading workflow.mmd. When that file is absent, the user sees "failed to read workflow.mmd" instead of the actual JSON error. Propagate the JSON error when workflow.mmd is missing.

In `@internal/tui/menu.go` around lines 64 - 70, Update the “👁️ Preview Workflow”
handling around previewMermaid so that when workflow.json exists but
workflow.mmd is missing, the error from processing workflow.json is propagated
instead of being replaced by a workflow.mmd read error. Preserve the existing
behavior when both files exist or when neither file exists.

Include the supported approval and resume flags in the command table.

cmd/termaid/main.go exposes --resume, --approve-intrusive, and --approve at Lines 70-72, but the run row lists only the short flags. Add these flags so the command reference covers the published run controls.

ffuf official documentation -u URL FUZZ input file list version latest

💡 Result:

The official documentation for ffuf (Fast web fuzzer) is maintained primarily on its GitHub repository [1]. The central hub for extended documentation and guides is the project's official Wiki [2]. To use an input file (wordlist) with the FUZZ keyword, you use the -w flag. The syntax is: ffuf -w /path/to/wordlist:FUZZ -u https://example.com/FUZZ The latest stable version of ffuf as of August 21, 2026, is v2.2.0, released on July 11, 2026 [3]. For more detailed information, you can refer to the following official resources: - Main Repository: https://github.com/ffuf/ffuf [1] - Official Wiki: https://github.com/ffuf/ffuf/wiki [2] - Releases: https://github.com/ffuf/ffuf/releases [4]

Make ffuf-1 consume URL templates, not the upstream file path.

{{input}} resolves to the httpx-1 output file. Since httpx-1 writes JSONL and ffuf -u requires a URL containing FUZZ, this command passes <httpx-output>/FUZZ instead of fuzzing each URL. Extract the URLs and invoke ffuf per URL, or add a transform before httpx-1 --> ffuf-1.

In `@workflow.mmd` at line 24, Update the ffuf-1 workflow so it consumes extracted
URL templates rather than the httpx-1 JSONL output path: transform each httpx
result into a URL containing FUZZ, then invoke ffuf per URL while preserving the
required ffuf -u input format.
