metagit-repo-impact

metagit-repo-impact is a skill for Claude Code, Codex from metagit-ai/metagit-cli. It costs 33 tokens per session (294 once invoked), scanned A, original, MIT.

A change-impact planner for codebases spread across multiple repositories. It combines workspace information with dependency analysis to estimate which projects and interfaces a change may affect.

In plain words
What is it for?
It helps identify affected repositories and interfaces, rank risky change points, and define tests and rollback checks without modifying files.
Why use it?
It helps reveal the likely blast radius before edits are made, especially for risky shared changes.

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

metagit-repo-impact 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 11d 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

Planning Repo Impact

Use this skill before risky or cross-repo modifications.

Workflow

  1. Identify target symbols/files for change.
  2. Use metagit workspace context to bound repository scope.
  3. Use graph impact tooling to estimate blast radius.
  4. Produce a change plan with test and rollback focus.

Commands

  • metagit workspace select --project <name>
  • MCP metagit_cross_project_dependencies with source_project and dependency_types before large cross-project edits
  • MCP metagit_project_context_switch to bound scope to one workspace project
  • npx gitnexus analyze on affected repos when graph_status is stale or missing
  • metagit gitnexus group sync -c .metagit.yml when cross-repo symbol impact is needed (after per-repo analyze)
  • npx gitnexus query / gitnexus impact for single-repo symbol analysis; gitnexus group impact for cross-index

Output Contract

Return:

  • impacted repositories and interfaces
  • highest-risk change points
  • minimum validation plan

Safety

  • Do not execute mutating steps in this planning phase.

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.
