multica-review-backend

multica-review-backend is a skill for Claude Code, Codex from it235/multica-best-practices. It costs 55 tokens per session (452 once invoked), scanned A, original, MIT.

A structured review process for backend API changes and their implementation. It checks the API agreement, design alignment, error handling, unit tests, and whether every acceptance criterion is met.

In plain words
What is it for?
Reviewing API contracts and backend code, checking edge cases and failures, assessing test coverage, and producing a PASS or FAIL decision with required fixes.
Why use it?
It provides a consistent way to find blocking problems before backend work is accepted. Re-reviews can also check whether earlier fixes were completed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

multica-review-backend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Backend Implementation Professional Review (BackendReviewer)

Structured professional review framework for backend implementation artifacts (API contract + implementation). Called by BackendReviewer; reviews the links BackendDev returns via multica-artifact-backend and code-class skill (Apifox / changed-file list), plus the architecture design ref Leader passes.

When to use

  • BackendReviewer receives a "review backend implementation" dispatch from Leader.
  • Entering a re-review round after implementation changes (check previous round's fix list item by item).

Review dimensions (conclusion per item)

  1. Contract quality: field naming, status codes, error model, versioning clear & self-consistent.
  2. Design fit: implementation aligned with Architect plan, deviations explained.
  3. Error handling: exception branches, timeouts, idempotency, boundaries covered.
  4. Unit-test sufficiency: key paths, boundaries, exception branches covered; no无效的 tests (mark & block).
  5. Acceptance mapping: implementation truly satisfies every AC-.

Output format

【Backend Review】<change link>
Conclusion: PASS / FAIL
Blocking items (required on FAIL, each: rationale / involved point / fix direction):
- ...
Suggestions (non-blocking):
- ...
Previous fix-list check (re-review): resolved X / unresolved Y
Round: N / 3

Conclusion + fix list reported to Leader; don't modify code or notify BackendDev yourself.

Boundaries

  • Review only backend contract & implementation, unit tests; not frontend, UI, requirements, architecture design itself, or test cases.
  • Don't replace Leader's generic gate (multica-verification skill).
  • Architecture-level disagreement goes to ArchReviewer; you own implementation-layer quality.
  • Still FAIL at round 3 → mark "escalate to human", hand to Leader, stop looping.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
