+# Agent guidance — qyl
+
+Repo-specific instructions for AI agents (Claude Code, Copilot, etc.) working in
+this repository. `CLAUDE.md` is a symlink to this file. For review-only rules see
+`.github/copilot-instructions.md`; this file is the authoring contract.
+
+## What qyl is
+
+qyl is an OpenTelemetry-compatible observability platform. OTel is the
+ingestion/instrumentation layer; qyl's product is the **collector, storage model,
+API, and investigation dashboard** built around telemetry. See `README.md` for the
+architecture diagram and run instructions.
+
+## Hard rules
+
+- **Contracts are single-sourced.** Public API request/response/DTO/schema shapes
+  live in the external `qyl-api-schema` TypeSpec repo and flow in via the
+  `Qyl.Api.Contracts` package. Do **not** add new public API models in
+  `qyl.collector`, and do **not** create a second contract source in this monorepo.
+  The path is `Schema → OpenAPI → DTO contracts → clients`. Runtime storage rows,
+  OTLP ingest wire types, and internal projections are fine **only** when they are
+  not returned as the product API contract.
+- **Generated files are not hand-edited.** Fix the generator or the schema input,
+  regenerate, then commit the result. This covers Roslyn `*.g.cs`, generated
+  protobuf, and the dashboard's generated TS API types (`npm run generate:ts`).
+- **`Version.props` is the single owner of package versions.** Never edit `<Version>`
+  lines or hard-code versions in a `.csproj`. Central Package Management
+  (`Directory.Packages.props`) governs package versions; nullable is enabled
+  repo-wide.
+- **Don't reintroduce removed code.** `eng/build/BuildVerify.cs` carries a
+  `removedCollectorTokens` guard that fails the build if deleted symbols come back.
+  If a check there fires, the fix is to keep the symbol gone — not to delete the
+  guard entry.
+
+## Toolchain
+
+- .NET SDK pinned by `global.json` (currently `10.0.301`, `rollForward:
+  latestFeature`), **C# 14**, built on the `ANcpLua.NET.Sdk` MSBuild SDK family.
+- Tests run on **Microsoft.Testing.Platform** (`global.json` → `test.runner`).
+- Dashboard: ESM, Node ≥ 20, React 19 + Vite + TanStack + Tailwind 4; no new
+  external runtime deps unless already declared in `package.json`.
+
+## Build / test / run
+
+```bash
+# Collector (REST API + OTLP ingest + DuckDB), serves on :5100, OTLP :4317/:4318
+dotnet run --project services/qyl.collector
+dotnet build services/qyl.collector/qyl.collector.csproj
+
+# Dashboard
+cd services/qyl.dashboard && npm install && npm run dev
+npm run build        # tsc -b && vite build
+npm test             # vitest
+
+# Local distributed runner (collector + dashboard together)
+dotnet run --project packages/Qyl.Run
+```
+
+## Branches, commits, PRs
+
+- **Branch prefix `claude/…` for agent-driven work.** The fleet `auto-merge.yml`
+  enables GitHub native auto-merge for `claude/` (and `copilot/`) branches once the
+  required status checks pass. Naming an agent branch `claude/<topic>` is the opt-in
+  signal that it is automation-authored and safe to auto-merge; other prefixes
+  (`fix/`, `refactor/`, `chore/`, `renovate/…`) do **not** auto-merge. Never commit
+  to `main` directly and never force-push `main`.
+- **Conventional Commits** for titles and squash-merge messages, with a scope:
+  `feat(run): …`, `fix(collector): …`, `refactor(run): …`, `chore!: …` for breaking
+  changes. Match the surrounding history.
+- Deliver through a PR; let CI (`.github/workflows/ci.yml`) go green before merge.
