Ideas marked `open` are prior findings nobody has pursued yet. + - Do NOT re-report an existing idea unless you found materially new evidence — the point of each run is *new* walls. + - Read prior runs' `## Prevention` sections too. A guardrail already proposed and still `open` must not be re-proposed as new — instead, if this run's findings are *more* evidence for it, note that under it (see step 6). + - Also check recent files in `.claude/thoughts/shared/research/` and `plans/` so you don't propose something already being worked on. An idea whose research prompt was already run (a matching research doc exists) counts as pursued. + +2. **Spawn parallel investigation sub-agents:** + + Launch these concurrently (adapt prompts to what the backlog already covers). All sub-agents must be told: *you are looking for friction as an end user/contributor would experience it; report specific evidence with file:line, not general critique.* + + - **codegen-analyzer** — pick 1–2 generator areas (e.g., a protocol under `src/codegen/generators/typescript/channels/protocols/`, the client generator, headers/parameters) and assess the *generated output shape*: what does the emitted API look like to consume? Anything confusing, inconsistent between protocols, or error-prone? + - **input-analyzer** — pick 1–2 input features (e.g., `oneOf`, refs, bindings, multiple messages per channel, OpenAPI parameter styles) and trace whether they survive into `Processed*SchemaData` faithfully or get dropped/defaulted silently. + - **codebase-locator / codebase-pattern-finder** — map test coverage: which generators/inputs/commands have unit + blackbox + runtime coverage, and which have holes (e.g., a protocol with no runtime test, a command with no test at all, website with nothing). + - **general-purpose** — docs drift: diff what `docs/` and `README.md` claim against current Zod schemas (`src/codegen/types.ts`), CLI flags (`src/commands/`), and `examples/`. Check `schemas/` and generated docs are in sync. Also review `.claude/` + `.cursor/rules` for instructions that no longer match reality (renamed scripts, moved files, stale paths). + - **general-purpose** — website: inspect `website/` for broken internal links, docs pages referencing removed/renamed config options, playground wiring to the browser bundle (`src/browser/`), and whether it can still build. + - **thoughts-locator** — anything in `.claude/thoughts/` already flagging known pain points worth elevating. + +3. **Do at least one hands-on end-user walkthrough yourself** (in the main context, in the scratchpad directory — never inside the repo): + + - Build the CLI if `dist/` is stale (`npm run build`), then act out the getting-started path exactly as documented: `codegen init` or a config copied from docs, run `codegen generate` against a real input (use a document from `examples/` or `test/`), and **read the generated files as if you had to ship them**. + - Note every stumble: unclear error messages, output that doesn't compile with `tsc`, confusing names, docs that told you the wrong flag or field. + - Cheap checks are in scope (running the CLI, `tsc --noEmit` on generated output, `npm test -- --testPathPattern=...`). Expensive checks (Docker runtime suite, full website build) only if a sub-agent finding needs confirmation and nothing cheaper can confirm it. + +4. **Distill to exactly 3 ideas:** + + Merge and rank all friction points. An idea qualifies only if it has: + + - **Evidence**: concrete file:line references, a repro, or a literal quote of the outdated doc/wrong output + - **A named victim**: which persona hits this, on which path ("a user generating NATS channels from an AsyncAPI doc with X will…") + - **User-visible consequence**: what silently breaks, confuses, or drives them away + + Drop anything that is maintainer-taste ("this could be refactored") rather than user-felt friction. + +5. **Rank the 3 ideas:** + + Score each on: + + - **Reach** — how many users walk this path (getting-started > niche protocol option) + - **Severity** — broken/wrong > confusing > merely suboptimal + - **Silence risk** — how likely the user leaves without telling us (first-run failures score highest) + - **Tractability** — can research plausibly lead to a scoped fix + + Order the ideas by this score (strongest first) and note which one you'd recommend and why — but the decision belongs to the user, not to this command. + +6. **Double back — why wasn't this caught?** + + Now drop the persona and put on the maintainer hat. For each of the 3 ideas, ask: **what guardrail should have failed before this reached a user, and why didn't it?** The problems you just found are the evidence; this step turns them into a permanent check. + + This runs deliberately *after* the ideas are settled — the sweep is scoped to the walls you actually found, not a generic audit. Reuse what step 2's test-coverage and `.claude`-drift agents already reported; spawn one more sub-agent for whatever they didn't cover rather than reading every workflow yourself. The guardrails to check: + + - **CI** — `.github/workflows/`: `pr-testing.yml`, `blackbox-testing.yml`, `runtime-testing.yml`, `examples-testing.yml`, `website-pr-testing.yml`, `lint-pr-title.yml`, `release.yml`, `.github/workflows/deploy/`. For the checks relevant to each idea, determine: does a job cover it at all; does it run on `pull_request` (or only on `schedule`/`workflow_dispatch`/`push` to main); is it path-filtered so the relevant change wouldn't trigger it; is it blocking or `continue-on-error`; does it actually assert (a step that generates output but never type-checks or diffs it is not a guardrail). + - **Test tiers** — is there a unit (`test/codegen/`), blackbox (`test/blackbox/`), or runtime (`test/runtime/typescript/`) test that *should* have covered this? Snapshot tests deserve suspicion: a snapshot that was updated to match wrong output is a guardrail that actively hid the bug. + - **Local gate** — `npm run prepare:pr` and what it chains (build → `generate:assets` → `lint:fix` → `test:update` → runtime regen), plus `npm run lint`, `typecheck`, `typecheck:test`. Would running the mandatory gate have surfaced this? If the gate regenerates artifacts but nothing fails when they drift, say so. + - **Claude/contributor setup** — `CLAUDE.md`, `.claude/CLAUDE.md`, `.cursor/rules/*.mdc`, `.claude/rules/*.md`, `.claude/skills/` (`add-generator`, `add-input-type`, `add-protocol`, `prepare-pr`, `troubleshoot`), `.claude/agents/`, `.claude/commands/`. Was the instruction that would have prevented this missing, wrong/stale, or present-but-easy-to-skip?
