branch-review

branch-review is a skill for Claude Code from juanmhidalgo/claude-plugins. It costs 32 tokens per session (2,581 once invoked), scanned A, original, MIT.

A branch and pull-request review guide that classifies findings by how seriously they affect merging and by confidence in the evidence. It covers concerns such as security, bugs, performance, error handling, tests, and style.

In plain words
What is it for?
Use it when judging whether branch changes or a pull request are ready to merge and reporting each concern with severity and confidence.
Why use it?
It gives code reviews consistent labels and makes clear which findings should block a merge versus merely being recommended.

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

branch-review 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 3d ago.

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.

Branch Review

Severity Classification

Level Block Merge? Examples
CRITICAL Yes Security vulnerabilities, data loss risks, breaking changes without migration
HIGH Should fix Bugs affecting users, performance regressions, missing error handling
MEDIUM Recommend Code smells, minor perf issues, missing non-critical tests
LOW Optional Style issues, refactoring opportunities, docs

Labels (orthogonal to severity)

Two labels change how a finding is read, not how severe it is. Both exist so that findings get surfaced and marked instead of silently dropped — a dropped finding is indistinguishable from a review that never looked.

Label Meaning Effect
nit Correct, but below the bar a senior engineer would raise in review Never blocks. Reported in its own group, collapsed by default.
pre_existing Real, but not introduced by these changes Never blocks this merge. Reported so it can become a ticket.

Do not use nit as a hedge on a finding you believe matters — that is what LOW severity is for. nit means "I am reporting this only for completeness".

Never suppress a pre_existing finding to keep the report clean. The rule is "do not block on pre-existing issues", not "do not mention them". If the changes made an existing problem materially worse, it is not pre_existing — it is a finding against these changes.

Confidence Classification

Severity answers "should this block merge?". Confidence answers "how strong is the evidence?". They are orthogonal — always pair both on every finding.

Level Meaning
HIGH Verified by reading the code path end to end. Evidence is direct: cited file:line you opened. Not "reproducible" — you cannot run anything; see Evidence provenance.
MEDIUM Strong inference from code patterns or framework behavior; would benefit from runtime confirmation before fixing.
LOW Speculation or pattern-based concern; may not apply in this specific context. Worth flagging, not over-weighting.

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.
