review-changes

A structured code-review guide that examines changes, affected execution paths, dependencies, and test coverage using a code knowledge graph.

In plain words
What is it for?
It is for reviewing changed code, finding affected functions and flows, checking whether high-risk changes have tests, suggesting test cases, and making a merge recommendation.
Why use it?
It helps reveal changes that may affect other parts of the program or lack tests, so review is based on risk and impact rather than only the edited lines.

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

review-changes 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 2d 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.

What it actually says

Review Changes

Perform a thorough, risk-aware code review using the knowledge graph.

Steps

  1. Run detect_changes_tool to get risk-scored change analysis.
  2. Run get_affected_flows_tool to find impacted execution paths.
  3. For each high-risk function, run query_graph_tool with pattern="tests_for" to check test coverage.
  4. Run get_impact_radius_tool to understand the blast radius.
  5. For any untested changes, suggest specific test cases.

Output Format

Provide findings grouped by risk level (high/medium/low) with:

  • What changed and why it matters
  • Test coverage status
  • Suggested improvements
  • Overall merge recommendation

Token Efficiency Rules

  • Start with get_minimal_context_tool(task="<your task>") before other graph tools.
  • Use detail_level="minimal" on all calls. Only escalate to "standard" when minimal is insufficient.
  • Target: complete any review/debug/refactor task in ≤5 tool calls and ≤800 total output tokens.
  • Read the implementation and its tests before changing code. The graph narrows scope; it does not replace the source.

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.

review-changes is a skill published in the GitHub repository tirth8205/code-review-graph (31,071 stars, last pushed 5d ago), licensed MIT. It adds 14 tokens to every session and 264 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
