reviewer

reviewer is a skill for Claude Code from parisgroup-ai/imersao-ia-setup. It costs 79 tokens per session (4,239 once invoked), scanned A, original, MIT.

A review process for checking a proposed feature, architecture decision, refactor, or code change before implementation. It records approved decisions in ADRs or PR documents; an ADR is a short written record of an important technical decision.

In plain words
What is it for?
Use it for significant changes or uncertain technical decisions. It guides understanding the request, proposing and revising a solution, getting approval, documenting it, and then implementing it.
Why use it?
It helps catch unsuitable plans before code is written and creates a traceable explanation of why a change was approved or rejected.

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

reviewer 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 13d 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.

Reviewer Skill

This skill enforces a structured validation process before implementation and generates formal documentation (ADR/PR) for traceability.

Core Principle

Never implement without explicit approval on significant changes. Document decisions for posterity.

When to Activate Reviewer Mode

Always Validate Before:

Action Risk Level Requires ADR Why Validate
New feature implementation 🔴 High ✅ Yes Wrong architecture is expensive
Database schema changes 🔴 High ✅ Yes Migrations are hard to undo
API contract changes 🔴 High ✅ Yes Breaking changes affect clients
Refactoring > 3 files 🟡 Medium ⚠️ Maybe Scope creep, unintended effects
Dependency upgrades 🟡 Medium ⚠️ Maybe Breaking changes, compatibility
Security-related changes 🔴 High ✅ Yes Vulnerabilities are critical
Performance optimizations 🟡 Medium ⚠️ Maybe Premature optimization
Deleting code/files 🔴 High ✅ Yes Data loss, broken references
Infrastructure changes 🔴 High ✅ Yes Downtime, cost implications
Third-party integrations 🟡 Medium ✅ Yes Vendor lock-in, costs

Skip Validation For:

  • Typo fixes
  • Comment updates
  • Formatting changes
  • Test additions (non-breaking)
  • Documentation updates
  • Single-line bug fixes (obvious)

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.
