# Tasks: enterprise-discord-client
**Change ID**: enterprise-discord-client
**Package**: `@suaveplan/discord-client`
**Target path**: `universal/social/discord-client`
**Prerequisite packages on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/retry`, `@suaveplan/crypto`
---
## 0. Pre-flight (non-negotiable)
- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.
## 1. Scaffold
- [ ] Create `universal/social/discord-client/` with `src/`, `tests/`, `src/__benchmarks__/` and all feature subdirectories per the layout in `proposal.md`.
- [ ] Write `package.json` at version `0.1.0` with `"type": "module"`, `"sideEffects": false`, correct `exports` map, `dependencies`, and `devDependencies`.
- [ ] Write `tsconfig.json` extending `@suaveplan/typescript-config/library.json`.
- [ ] Write `vitest.config.ts` using `createTestConfig()` from `@suaveplan/testing/config`.
- [ ] Add `lint`, `typecheck`, `test`, `test:coverage`, `build`, `docs:check` scripts.
---
## 2. Types + errors
- [ ] `src/types/common.ts` — `DiscordClientOptions`, `MessagePayload`, `WebhookPayload`, `ExecuteWebhookOptions`, `ThreadOptions`, `DiscordMessage`, `DiscordChannel`, `DiscordGuild`, `DiscordMember`, `DiscordEmbed`, `DiscordInteraction`.
- [ ] `src/types/common.md` (≥200 words, both examples, API reference).
- [ ] `src/error-codes.ts` — `DiscordErrorCode` (7 codes), metadata, register, eager call.
- [ ] `src/types/schemas.ts` + `schemas.md` — Zod schemas.
---
## 3. Core modules
- [ ] **`src/core/rate-limiter/`** — `RateLimiter`: parses `X-RateLimit-Bucket`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` headers; tracks per-bucket state; `waitIfNeeded(bucket)` returns a `Promise` that resolves after the reset time when `remaining === 0`. Tests: no-op when remaining > 0, waits when remaining = 0, multiple buckets tracked independently.
- [ ] **`src/core/api-caller/`** — `ApiCaller`: wraps `fetch` to `https://discord.com/api/v10/`; sets `Authorization: Bot` header; invokes `RateLimiter.waitIfNeeded`; parses JSON; throws `DISCORD_API_ERROR` on non-2xx; handles 429 (uses `retry_after`). Tests: success, 401, 404, 429 rate-limit.
- [ ] **`src/core/discord-client/`** — `DiscordClient`: implements all public methods via `ApiCaller`. Tests: `sendMessage`, `editMessage`, `deleteMessage`, `addReaction`, `createThread`, `getGuild`, `getMember`, `sendWebhook`.
- [ ] **`src/embeds/embed-builder/`** — `createEmbed()`: fluent builder; `build()` returns `DiscordEmbed`. Tests: title+description, with fields, with footer, with image, timestamp auto-set.
- [ ] **`src/interactions/interaction-verifier/`** — `verifyDiscordInteraction(body, signature, timestamp, publicKey)`: Ed25519 verify via `@suaveplan/crypto`. Tests: valid, tampered body, wrong key.
- [ ] **`src/interactions/interaction-parser/`** — `parseInteraction(body)`: Zod validation. Tests: slash command, button component, select component, invalid throws.
---
## 4. OTel instrumentation
- [ ] Span `discord.api_call` with attribute `discord.endpoint`; counter `discord.api_total`; histogram `discord.api_duration_ms`.
---
## 5. Property-based tests (`tests/property.test.ts`)
- [ ] Embed builder: for arbitrary sequences of field additions, `build()` produces `fields` array with correct structure and length.
- [ ] Rate-limiter bucket: parsing arbitrary valid header combinations never throws and always produces a non-negative remaining count.
---
## 6. Benchmarks (`src/__benchmarks__/discord-client.bench.ts`)
- [ ] `createEmbed` builder chain (10 fields) 100 000 times.
---
## 7. Docs + verify
- [ ] One `.md` per implementation file (≥200 words, both examples, API reference). Root `README.md`.
- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/discord-client` — green.
- [ ] `bunx turbo test:coverage --filter=@suaveplan/discord-client` — 100%.
- [ ] `bun scripts/publish.ts --package @suaveplan/discord-client`.
- [ ] Archive: `openspec/archive/2026-04-24-enterprise-discord-client/`.
