What is gitnexus-impact-analysis?

A code-dependency analysis tool for finding what uses a file, function, or other code and what could be affected by changing it.

Use it to find direct and indirect dependants, inspect affected execution flows, map current changes, and assess change risk.

It shows the likely blast radius of an edit before changes are made or committed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.00793
Opus 5.5	$0.00020	$0.00317
Sonnet 5.5	$0.00010	$0.00159
Haiku 4.5	$0.00005	$0.00079

Security

Grade A, and why

gitnexus-impact-analysis 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 2mo 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.

Impact Analysis with GitNexus

When to Use

"Is it safe to change this function?"
"What will break if I modify X?"
"Show me the blast radius"
"Who uses this code?"
Before making non-trivial code changes
Before committing — to understand what your changes affect

Workflow

1. gitnexus_impact({target: "X", direction: "upstream"})  → What depends on this
2. READ gitnexus://repo/{name}/processes                   → Check affected execution flows
3. gitnexus_detect_changes()                               → Map current git changes to affected flows
4. Assess risk and report to user

If "Index is stale" → run npx gitnexus analyze in terminal.

Checklist

- [ ] gitnexus_impact({target, direction: "upstream"}) to find dependents
- [ ] Review d=1 items first (these WILL BREAK)
- [ ] Check high-confidence (>0.8) dependencies
- [ ] READ processes to check affected execution flows
- [ ] gitnexus_detect_changes() for pre-commit check
- [ ] Assess risk level and report to user

Understanding Output

Depth	Risk Level	Meaning
d=1	WILL BREAK	Direct callers/importers
d=2	LIKELY AFFECTED	Indirect dependencies
d=3	MAY NEED TESTING	Transitive effects

Risk Assessment

Affected	Risk
<5 symbols, few processes	LOW
5-15 symbols, 2-5 processes	MEDIUM
>15 symbols or many processes	HIGH
Critical path (auth, payments)	CRITICAL

Tools

gitnexus_impact — the primary tool for symbol blast radius:

gitnexus_impact({
  target: "validateUser",
  direction: "upstream",
  minConfidence: 0.8,
  maxDepth: 3
})

→ d=1 (WILL BREAK):
  - loginHandler (src/auth/login.ts:42) [CALLS, 100%]
  - apiMiddleware (src/api/middleware.ts:15) [CALLS, 100%]

→ d=2 (LIKELY AFFECTED):
  - authRouter (src/routes/auth.ts:22) [CALLS, 95%]

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.
