Use when adding or modifying an HTTP endpoint, reviewing an OpenAPI spec or HTTP route diff, or deciding whether an HTTP API change breaks consumers. Do not use as a protocol-compatibility checklist for gRPC/protobuf, GraphQL, WebSockets, or other non-HTTP/JSON interfaces.\n---\n\n# old-coder-api\n\nInspired by Sean Goedecke, *Everything I know about good API design* (2025-08-24).\n\nThis skill covers HTTP/JSON contract and operability concerns. Its compatibility rules assume JSON consumers. For gRPC/protobuf, GraphQL, WebSockets, or another protocol, apply the transport-independent principles only alongside that protocol's own compatibility rules. This is not a substitute for a full application-security review.\n\n**Good APIs are boring.** For the people who build them, an API is a product. For the people who use them, it is a tool in the way of something else. Every minute a consumer spends thinking about your API instead of their goal is waste. An interesting API is a bad API — or would be a better one if it were less interesting.\n\nTwo failure modes an agent falls into by default, and this skill exists to stop both:\n\n1. **Inventing.** Producing a clever, bespoke interface where the boring conventional one would do.\n2. **Breaking.** Renaming, restructuring, or tightening a field because it reads better now — and silently breaking every downstream caller.\n\n**Composition with `old-coder`:** when both skills apply, this skill owns the\nHTTP/JSON contract while `old-coder` owns workflow order, SPEC approval, the\ngauntlet, and EVIDENCE. Run Step 0 and the gates before SPEC approval; put the\nsurviving API constraints and risks into SPEC and verify them through the\ngauntlet. For review-only work with no implementation, use this skill's review\nformat without manufacturing a development loop.\n\n## Step 0 — establish scope before designing anything\n\nAnswer these three, out loud, before writing a route:\n\n| Question | Why it changes the work |\n|---|---|\n| **Public or internal?** Can you ship code for every consumer? | Internal: breaking changes are affordable, complex authentication is fine, non-engineer ergonomics don't matter. Public: none of that holds. |\n| **Existing surface or greenfield?** | Existing → run `references/breaking-changes.md` **first**; compatibility outranks every improvement below. |\n| **Does the product's resource model support this API?** | API design tracks the product's basic resources. If the resources are awkward (state machines with no name, records that only exist inside a job, parent/child relations that aren't modeled), the API will be awkward no matter how carefully you design it. Say so instead of papering over it. |\n\n**Honesty rule for step 0:** when the ugliness comes from the underlying model, name it and propose the model fix as the real option. A background-job-polling interface bolted onto a read that *should* be a read is how the worst APIs happen — technical constraints that the UI hides get laid bare in the API, forcing consumers to understand far more of your system than they should have to.\n\n## The gates\n\nRun every gate. Use **✓** only for a verified pass, **✗ + concrete fix** for a verified failure, **N/A + reason** only when the gate truly does not apply, and **? + reason** when it remains unverified. Never skip silently.\n\n### 1. Boring\nA competent consumer should be able to guess this endpoint before reading any docs.\n- Resources are the product's nouns (`/issues`, `/projects`, `/users`), plural, stable.\n- Standard verbs and status codes, following the established convention of this API. Use `400` for a general client error; use `422` only when the content type and syntax are valid but the contained instructions cannot be processed. Use `404` for missing and `429` for rate-limited.\n- Standard field names: `id`, `created_at`, `next_page`, `url`. Match the names the rest of *this* API already uses — internal consistency beats external convention when they conflict.\n- REST + JSON unless there's a reason. An established, internally consistent HTTP RPC surface can also be boring; do not rename it to resource paths for REST purity. Don't relitigate HATEOAS or JSON-vs-anything; it isn't important.\n- **Anything surprising needs a written justification line.** If you can't write one, make it boring.\n\n### 2. Don't break userspace\nApplies only to changes on an existing surface. Full matrix in `references/breaking-changes.md`.\n- Additive is fine: new endpoints, new optional params, **new response fields**. Consumers are expected to ignore unknown fields.\n- Removing a field, renaming it, changing its type, moving it (`user.address` → `user.details.address`), narrowing an enum, or tightening validation is a break. Don't, even if it's neater. The HTTP `referer` header is a misspelling and it is still there.\n- If a break is genuinely unavoidable: versioning, as a **last resort** — see the reference.\n\n### 3. Authentication: make the simplest safe path easy\nMany server-to-server integrations start life as a `curl` or a 20-line script. For developer-facing server-to-server APIs, default to simple, scoped, revocable API keys.\n- Use OAuth or another short-lived or sender-constrained flow instead for browser/mobile clients, user-delegated access, high-sensitivity data, or environments where policy requires it. Do not ship long-lived bearer credentials into those clients.\n- For every credential type, define scope, rotation, revocation, secure transport, and a way to identify or disable the credential during an incident.\n- N/A for internal credential ergonomics: use the mechanism the infrastructure already provides (mTLS, workload identity, service tokens), while still verifying its operational controls.\n\n### 4. Authorization: enforce who may do what to which resource\nAuthentication identifies a caller; it does not authorize an action. For every endpoint, identify the actor, action, resource, and tenant boundary.\n- Enforce authorization server-side on the resolved resource. Do not trust a caller-supplied `tenant_id`, owner ID, role, or scope without checking it against the authenticated principal.\n- Apply the same checks to list, search, bulk, export, nested-resource, and indirect lookup paths; filtering after fetching is not an authorization boundary.\n- N/A only for intentionally anonymous public operations, with a one-line reason. For security-sensitive changes, require a dedicated security review in addition to these API gates.\n\n### 5. Idempotency on anything that takes action\nA `500` or a timeout tells the caller nothing about whether the action happened. Without an idempotency key, the caller must choose between a lost operation and a duplicate one.\n- Every operation that is not already idempotent and creates, triggers, or applies a relative change accepts an idempotency key (header or param); repeat keys return the original result instead of acting twice.\n- Keep it **optional for low-stakes operations** where an occasional duplicate is cheaper than added adoption friction.\n- When a duplicate is unacceptable — payments, transfers, medication, irreversible external side effects — require an idempotency key or an intrinsic unique operation ID, and enforce deduplication atomically with the effect.\n- Not needed for reads (harmless) or `DELETE /comments/32` (the ID *is* the key — the retry just 404s). Exception: non-ID-scoped operations like \"delete the most recent\".\n- Storage recipe in `references/patterns.md`.\n\n### 6. Blast radius, rate limits, killswitch\nUI users are limited by the speed of their hands. **Anything you expose via API is called at the speed of code**, forever, in a loop, by someone who read no docs.\n- Before shipping: write down what one caller in a tight `while true` loop costs you. Fan-outs, `/index` endpoints, bulk imports, and anything doing per-record work in a request are the dangerous ones.\n- Rate limit everything, with **tighter limits on expensive operations**.\n- Return `X-RateLimit-Remaining` and `Retry-After` so well-behaved clients can back off — that metadata is what lets you set stricter limits than you otherwise could.\n- Keep a per-consumer killswitch. You will need it during an incident caused by an integration you never imagined.\n\n### 7. Pagination\n- Any collection that could plausibly grow large: **cursor-based**, always. `WHERE id > :cursor ORDER BY id LIMIT :n` stays fast at record one million; `OFFSET` gets slower every page and the migration away from it later is expensive.\n- Bounded-forever collections (a user's API keys, a project's 5 environments): page/offset is fine.\n- Never return an unbounded list. Always include `next_page` (URL or cursor) so consumers don't compute it.\n\n### 8. Expensive fields are optional and off by default\nIf a field needs an extra service call, a join over a big table, or a computation, don't put it in the default response.\n- Gate it behind `?include=subscription` / an `includes[]` array; keep the default response cheap and **constant-cost**.\n- This is the useful 20% of the GraphQL idea without the cost.\n- **Don't propose GraphQL** unless the user asks or the codebase is already GraphQL: high barrier for non-engineers, arbitrary client-crafted queries complicate caching and multiply edge cases, and the backend is fiddlier. It's a last resort, not a default.\n\n### 9. No implementation leakage\nRead the response as a stranger. Does using it correctly require knowing how you store things?\n- Leaks: `next_comment_id` chains the client must walk; a `POST /fetch_job` + poll dance for what should be a `GET`; internal enum values; internal table IDs; pagination whose page size depends on your shard layout.\n- Either hide it behind a boring interface, or state the debt explicitly in the PR — don't let it slip into a public contract unremarked.\n\n## Deliberately not gates\n\nGuard against over-design as hard as under-design:\n\n- **Don't build versioning machinery up front.** A `/v1/` prefix is itself a public product choice, not a free placeholder. Adopt path or header versioning only when the product's compatibility policy calls for it; do not build multi-version negotiation before a second version exists.\n- **Don't add `includes` or cursors to internal endpoints with one caller and a bounded result set.** The Pagination and Expensive fields gates are about potentially large or expensive responses. For Idempotency, caller count does not remove retry risk: omit it only when the operation is already idempotent or duplicate effects are explicitly acceptable.\n- **Don't rewrite a working API to be prettier.** Prettiness is not worth a compatibility break, and it isn't worth the review time either.\n- **Remember API quality is marginal.** If the product is valuable, people integrate with a terrible API (Facebook, Jira). If it isn't, a beautiful API won't save it. API quality decides between two roughly equivalent products; having *no* API at all is the real defect. So: apply these gates, don't gold-plate past them.\n\n## Review output format\n\nWhen reviewing rather than writing, report only findings that survive verification and skip taste. For repository code, specs, and diffs, cite `file:line`. For published contracts outside the repository, cite a stable URL and exact section; source-code evidence must use an immutable commit permalink, not a moving branch. A missing public guarantee means consumers cannot rely on the behavior; it does **not** prove that the backend lacks an undocumented implementation. Give a gate `✓` only when the reviewed evidence supports it. When repository context is available, inspect beyond the diff instead of treating silence as a pass. If the input is intentionally limited and further evidence is unavailable, use `? (unverified: <reason>)`; reserve `N/A` for a gate that tru","tagline":"Design, change, or review an HTTP/JSON API surface — endpoints, request/response shapes, authentication and authorization, pagination, idempotency, rate limits, versioning, and deprecations.
