impact-audit

impact-audit is a skill for Claude Code from n24q02m/better-code-review-graph. It costs 35 tokens per session (1,520 once invoked), scanned A, original, Apache-2.0.

A planning-time impact check that traces a proposed code change across multiple related repositories. It reports which repositories and components may need coordinated updates.

In plain words
What is it for?
Use it before implementing a cross-repository change to map affected code and determine what must ship together.
Why use it?
It prevents teams from changing one repository while missing dependent code elsewhere. This is especially useful when a change affects a shared function, parameter, or return value.

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

impact-audit 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Impact Audit

Scope a planned change before writing it. Answers "if I change this, what else has to change, and in which repositories" -- across a federation of repositories, not just the one you have open.

Run this while the change is still a proposal. Once code is written, review-delta and review-pr review what actually changed.

Command surface: run the local CLI through the coding harness shell. Examples use the installed better-code-review-graph command; from a source checkout, prefix it with uv run. No MCP mapping is required. Use better-code-review-graph query --help for the actions reference.

Steps

  1. State the change under audit in one line before querying anything -- for example "add a required tenant_id parameter to create_session". The audit is only meaningful against a specific proposed edit, because the risky part differs: adding a required parameter breaks callers, changing a return type breaks consumers, renaming breaks both plus anything resolving the name dynamically.

  2. Make sure every repository that could be affected is in the graph. A blast radius is only as wide as the graph:

    • better-code-review-graph graph stats --repo-root "<path-a>" -- confirm the graph exists and note files_count.
    • better-code-review-graph graph build --full-rebuild --repo-root "<path-a>" --roots "<path-b>" -- federate the additional repositories into the same graph. Each root is registered and its files tagged with a repo_id.
    • Without federation, a cross-repo audit will report a clean radius simply because the consumers were never indexed. Say so in the report rather than implying the change is contained.
  3. Locate every definition of the symbol with better-code-review-graph query search --search-query "<name>" --repo-root "<path-a>", leaving --repo unset so the search spans all federated repositories. Two repositories may define the same name for unrelated purposes -- resolve which definition is actually the target before tracing, and note any same-named decoys so a later reader does not re-open the question.

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.

impact-audit is a skill published in the GitHub repository n24q02m/better-code-review-graph (67 stars, last pushed yesterday), licensed Apache-2.0. It adds 35 tokens to every session and 1,520 once invoked, about $0.0002 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.
