http-rest-fundamentals Stinger
Procedural arsenal for http-rest-fundamentals-worker-bee, the HTTP and REST protocol authority in the Hive.
This stinger encodes the practical reference material needed to audit HTTP and REST usage authoritatively against RFC semantics. It is organized around eight concern areas, each with its own guide, plus templates for common deliverables and worked examples for the most frequently misunderstood scenarios.
Paired Bee: .claude/agents/http-rest-fundamentals-worker-bee.md
Command Brief: ai-tools/command-briefs/http-rest-fundamentals-worker-bee-command-brief.md
First action when this stinger is loaded
Read these in order before doing anything:
guides/00-principles.md -- RFC-first reasoning model; safety vs idempotency; the seven REST constraints; why "RESTful" is usually a lie. This is the foundation every other guide builds on.guides/10-failure-modes.md (if it exists; otherwise check reports/README.md) -- the catalog of common HTTP anti-patterns and their impact classifications.- The guide most relevant to the current task (see index below).
Then pick the appropriate template from templates/ for the deliverable the Bee is producing.

Critical directives (lifted from Command Brief)
- Cite the RFC section for every status-code and method ruling. Why: RFC citations are the only way the developer can verify the ruling and learn the underlying principle.
- Never conflate HTTP-layer correctness with framework convention. Why: frameworks sometimes diverge from RFC semantics for DX reasons; the distinction matters for interoperability.
- Flag CORS wildcard-with-credentials as Critical, not Informational. Why: this misconfiguration is exploitable by cross-origin attackers.
- Do not audit authentication tokens, JWTs, or session cookies -- hand off to
auth-worker-bee. Why: boundary prevents duplicate findings.
- Do not audit TLS, cipher suites, or certificate validity -- hand off to
devops-worker-bee. Why: same boundary rationale; this stinger stays at the application layer.
Key research signals (from scripture-historian, 2026-05-20)
The following findings from the research sweep are high-signal for this stinger:
- HTTP/3 split reality: CDN users (Cloudflare, Fastly, Akamai) get HTTP/3 transparently at the edge. Self-hosted origins must configure QUIC explicitly (nginx 1.25+, Caddy, Envoy). Node.js, Go stdlib, Python stdlib, and Ruby have no first-class HTTP/3 as of 2026.
- CORS triple-wildcard prohibition:
Access-Control-Allow-Origin: * is forbidden in combination with Access-Control-Allow-Credentials: true. The browser throws immediately. The wildcard also applies to Access-Control-Allow-Methods: * and Access-Control-Allow-Headers: * -- those too are rejected when credentials are involved in some browsers.
- RFC 9110 renamed 422: "Unprocessable Entity" is now officially "Unprocessable Content" per RFC 9110. The status code number is unchanged.
- RFC 9457 is current for error bodies:
application/problem+json format (RFC 9457, superseding RFC 7807) is the standard for structured error responses.
- Auth-before-CORS gotcha: OPTIONS preflights arrive without credentials. Any middleware that requires authentication before CORS headers are set will reject preflights with 401, breaking CORS for all non-simple requests.
- ETag + CDN: ETags are often stripped or rewritten by CDNs unless explicitly preserved. Audits should check whether ETags survive the CDN layer.
