+# Fix TS2589: component types too deep
+
+## Context
+
+Registering `@vllnt/convex-api-keys` as a Convex component triggers TS2589 (type instantiation excessively deep) in the host app's generated `api.d.ts`. Root cause: `src/component/_generated/api.ts` was not regenerated after v0.2.0 removed 3 sub-components. It still declares `ComponentApi` imports for `@convex-dev/rate-limiter`, `@convex-dev/aggregate`, and `@convex-dev/crons` — none of which are used. `package.json` still lists all 3 as `dependencies`, pulling their type definitions into consumers' `node_modules`.
+
+## Codebase Impact
+
+| Area | Impact | Detail |
+|------|--------|--------|
+| `src/component/_generated/api.ts:52-57` | MODIFY | Remove 3 stale `ComponentApi` imports — keep only `shardedCounter` |
+| `package.json:53-56` | MODIFY | Remove `@convex-dev/rate-limiter`, `@convex-dev/aggregate`, `@convex-dev/crons` from `dependencies` |
+| `package.json:4` | MODIFY | Bump version (patch or prerelease) |
+| `pnpm-lock.yaml` | AFFECTED | Shrinks after removing 3 deps |
+| `src/component/convex.config.ts` | AFFECTED | Already correct — only `shardedCounter` — no change needed |
+| `src/component/_generated/component.ts` | AFFECTED | Already correct — no change needed |
+| `src/component/mutations.ts` | AFFECTED | Only imports `shardedCounter` — no change needed |
+| `src/component/queries.ts` | AFFECTED | Only imports `shardedCounter` — no change needed |
+| `CLAUDE.md` | AFFECTED | Already says "Single child component: @convex-dev/sharded-counter" — correct |
+| `README.md` | MODIFY | Remove mentions of rate-limiter/aggregate/crons if present |
+| `package.json:88` (keywords) | MODIFY | Remove `"rate-limiting"` keyword — no longer a feature |
+
+**Files:** 0 create | 3 modify | 5 affected
+**Reuse:** `pnpm build:codegen` regenerates `_generated/api.ts` correctly from current `convex.config.ts`
+**Breaking changes:** None — removing phantom types that were never accessible at runtime
+**New dependencies:** None — removing 3
+
+## User Journey
+
+1. Developer installs `@vllnt/convex-api-keys` and adds `app.use(apiKeys)` in `convex.config.ts`
+   -> Convex codegen generates host app `api.d.ts` with component types
+   -> Host app typechecks cleanly (no TS2589)
+
+2. Developer uses `action()` / `query()` / `mutation()` from `_generated/server`
+   -> TypeScript resolves through `FilterApi<...>` recursion without exceeding depth limit
+   -> IntelliSense works normally
+
+Error: Developer has cached `node_modules` from older version
+   -> `pnpm install` pulls only `@convex-dev/sharded-counter` (not 3 phantom deps)
+   -> Clean install, no stale types
+
+## Acceptance Criteria
+
+### Must Have (BLOCKING)
+
+- [ ] AC-1: GIVEN a host app with `app.use(apiKeys)` WHEN running `npx convex dev` and `tsc --noEmit` THEN typecheck passes without TS2589
+- [ ] AC-2: GIVEN `src/component/_generated/api.ts` WHEN inspecting `components` export THEN only `shardedCounter` is declared
+- [ ] AC-3: GIVEN `package.json` WHEN inspecting `dependencies` THEN only `@convex-dev/sharded-counter` is listed
+
+### Error Criteria (BLOCKING)
+
+- [ ] AC-E1: GIVEN existing tests WHEN running `pnpm test` THEN all tests pass (no regressions from dep removal)
+
+### Should Have
+
+- [ ] AC-4: GIVEN `package.json` keywords WHEN inspecting THEN `"rate-limiting"` is removed (no longer a feature)
+
+## Scope
+
+- [ ] 1. Regenerate `_generated/api.ts` via `pnpm build:codegen` -> AC-1, AC-2
+- [ ] 2. Remove 3 phantom deps from `package.json` dependencies -> AC-3
+- [ ] 3. Remove stale keyword from `package.json` -> AC-4
+- [ ] 4. Run `pnpm install` to update lockfile -> AC-3
+- [ ] 5. Verify existing tests pass -> AC-E1
+- [ ] 6. Check README.md for stale sub-component references -> AC-1
+
+### Out of Scope
+
+- Version bump (separate release step)
+- Host app integration test (manual verification by maintainer)
+- Example app `_generated/` cleanup (separate concern, uses `AnyApi` escape hatch)
+
+## Quality Checklist
+
+### Blocking
+
+- [ ] All Must Have ACs passing
+- [ ] All Error Criteria ACs passing
+- [ ] All scope items implemented
+- [ ] No regressions in existing tests
+- [ ] `pnpm build:codegen` succeeds
+- [ ] `pnpm typecheck` passes
+- [ ] `pnpm lint` passes
+
+### Advisory
+
+- [ ] `pnpm-lock.yaml` shrinks (fewer transitive deps)
+- [ ] Code follows existing project patterns
+
+## Test Strategy
+
+Runner: vitest 3.0.0 (edge-runtime) | E2E: none (backend component library) | TDD: verify existing tests pass
+AC-1 -> manual: `pnpm build:codegen && pnpm typecheck` | AC-2 -> inspect file | AC-3 -> inspect package.json | AC-E1 -> `pnpm test`
+Mocks: none (convex-test provides in-memory DB)
+
+## Analysis
+
+**Assumptions:** Stale `_generated/api.ts` is sole cause -> VALID (grep confirms only file referencing removed packages; `convex.config.ts` and `component.ts` already correct) | `pnpm build:codegen` regenerates correctly -> VALID (script runs `convex codegen --component-dir ./src/component` which reads current `convex.config.ts`) | No source code uses removed packages -> VALID (grep shows zero imports outside `_generated/api.ts`)
+**Blind Spots:** [ops] Published npm tarball includes `src/` — consumers may resolve stale `_generated/api.ts` from cache until new version published. Impact: fix only takes effect after publish.
+**Failure Hypothesis:** IF `pnpm build:codegen` also requires the removed packages installed to generate THEN codegen fails BECAUSE convex CLI reads `node_modules` for sub-component resolution -> LOW severity, mitigate by running codegen before removing deps.
+**The Real Question:** Confirmed — spec solves the right problem. The TS2589 is caused by stale generated types declaring 4 sub-components when only 1 exists. Removing the phantom declarations directly addresses the recursive `FilterApi` depth explosion.
+**Open Items:** [question] Should we run codegen before or after removing deps from package.json? -> explore (test both orders)
+
+## Notes
+
+### Ship Retro (2026-03-27)
+**Estimate vs Actual:** 1h -> 0.5h (200% accuracy)
+**What worked:** Root cause was immediately clear from diffing `convex.config.ts` (1 sub-component) vs `_generated/api.ts` (4 sub-components). Parallel discovery agents accelerated context gathering.
+**What didn't:** `pnpm build:codegen` requires a Convex deployment, so had to manually edit the generated file instead. Not a problem — the edit was trivial.
+**Next time:** For generated file fixes, check if codegen can run locally before planning it as the primary approach.
