📝 Walkthrough

Walkthrough

The pull request replaces general contributor guidance with focused agent instructions. It adds scoped guidance for repository workflows, benchmarks, documentation, E2E tests, examples, router packages, and Start runtime packages.

Changes

Repository Guidance

Layer / File(s) Summary
Repository workflows and test execution
AGENTS.md, docs/AGENTS.md, e2e/AGENTS.md, examples/AGENTS.md
The guidance defines repository scope, setup, Nx usage, validation targets, documentation checks, E2E execution, port handling, shared test helpers, and example-app workflows.
Benchmark and bundle validation
AGENTS.md, benchmarks/AGENTS.md
The guidance defines baseline and candidate benchmark comparison, performance targets, bundle-size fixtures, and gzip delta reporting.
Router package contracts and validation
packages/AGENTS.md, packages/history/AGENTS.md, packages/router-core/AGENTS.md, packages/router-generator/AGENTS.md, packages/router-plugin/AGENTS.md, packages/router-ssr-query-core/AGENTS.md
The package guidance records routing ownership, identity and navigation contracts, history batching, route-cache and HMR behavior, generator file-write rules, plugin invariants, SSR query cleanup, and required validation commands.
Start runtime and build contracts
packages/start-client-core/AGENTS.md, packages/start-plugin-core/AGENTS.md, packages/start-server-core/AGENTS.md
The guidance records Start compiler and adapter rules, RPC framing and cancellation contracts, trusted context merging, request asset caching, SSR response ownership, and client/server frame compatibility.

Merge Risk: 🔵 Low · up to 07d86

This documentation-only change adds agent workflows, but one mandatory bundle-validation link is unusable and one router-core instruction remains unclear. These issues do not affect runtime behavior, but should be corrected so contributors can reliably follow the intended validation guidance.

# E2E tests

- Read the project's `package.json` and test config. Inspect resolved targets with `CI=1 NX_DAEMON=false pnpm nx show project <name> --json`: `nx.metadata.playwrightModes` generates modes, variants, and shards. The aggregate `test:e2e` can also run extra package-script suites. For focused Playwright runs, select an executable test target (a mode/shard target when inferred) and append filters after `--` (e.g. `-- tests/navigation.spec.ts --grep "redirect"`).

@beaussan i think i asked you before, but are CI=1 NX_DAEMON=false still useful when running nx commands from agents (sandboxed? from worktrees? from separate local clones of the repo? ...)

- Reusing loader work/data does not reuse `beforeLoad`: each active preload and subsequent navigation reruns it. Keep its returned context separate from reusable route-context contributions; see [`tests/public-preload-lane-contract.test.ts`](tests/public-preload-lane-contract.test.ts).
- Code emitted into HTML (`?script-string` entries and RawStream factories) executes without module scope. Keep it self-contained; pass dependencies explicitly. Validate emitted strings through the existing execution tests after refactors (`RawStream`, `scroll-restoration-script`, `tsr-script-teardown`).
- Before changing SSR streaming or hydration transport, read [`src/ssr/STREAMING.md`](src/ssr/STREAMING.md). Byte ordering, renderer safe points, and completion handling have framework-specific contracts.
- Backpressure tests are excluded from normal unit runs. For buffering/backpressure changes, run the gated suite below. Its memory case requires exposed GC; bypass Nx cache so a previous run with the gate disabled cannot count as validation.

Clarify the GC requirement.

Replace “requires exposed GC” with “requires GC to be exposed.” The revised wording states the runtime requirement more clearly.

Proposed wording
-Its memory case requires exposed GC; bypass Nx cache so a previous run with the gate disabled cannot count as validation.
+Its memory case requires GC to be exposed; bypass Nx cache so a previous run with the gate disabled cannot count as validation.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Fix the broken skill link.

The branch stores the skill at skills/bundle-size-optimization/SKILL.md. The referenced .agents/skills/bundle-size-optimization/SKILL.md path returns 404, so agents cannot follow the required final bundle-validation workflow. (raw.githubusercontent.com)
