Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00053 | $0.01043 |
| Opus 5.5 | $0.00021 | $0.00417 |
| Sonnet 5.5 | $0.00011 | $0.00209 |
| Haiku 4.5 | $0.00005 | $0.00104 |
Grade A, and why
gitnexus-refactoring 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 1mo 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.
This is a copy
86% identical to gitnexus-refactoring — 58 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Refactoring with GitNexus
When to Use
- "Rename this function safely"
- "Extract this into a module"
- "Split this service"
- "Move this to a new file"
- Any task involving renaming, extracting, splitting, or restructuring code
Workflow
1. gitnexus_impact({target: "X", direction: "upstream"}) → Map all dependents
2. gitnexus_query({query: "X"}) → Find execution flows involving X
3. gitnexus_context({name: "X"}) → See all incoming/outgoing refs
4. Plan update order: interfaces → implementations → callers → tests
If "Index is stale" → run
npx gitnexus analyzein terminal.
Checklists
Rename Symbol
- [ ] gitnexus_rename({symbol_name: "oldName", new_name: "newName", dry_run: true}) — preview all edits
- [ ] Review graph edits (high confidence) and ast_search edits (review carefully)
- [ ] If satisfied: gitnexus_rename({..., dry_run: false}) — apply edits
- [ ] gitnexus_detect_changes() — verify only expected files changed
- [ ] Run tests for affected processes
Extract Module
- [ ] gitnexus_context({name: target}) — see all incoming/outgoing refs
- [ ] gitnexus_impact({target, direction: "upstream"}) — find all external callers
- [ ] Define new module interface
- [ ] Extract code, update imports
- [ ] gitnexus_detect_changes() — verify affected scope
- [ ] Run tests for affected processes
Split Function/Service
- [ ] gitnexus_context({name: target}) — understand all callees
- [ ] Group callees by responsibility
- [ ] gitnexus_impact({target, direction: "upstream"}) — map callers to update
- [ ] Create new functions/services
- [ ] Update callers
- [ ] gitnexus_detect_changes() — verify affected scope
- [ ] Run tests for affected processes
Tools
gitnexus_rename — automated multi-file rename:
gitnexus_rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: true})
→ 12 edits across 8 files
→ 10 graph edits (high confidence), 2 ast_search edits (review)
→ Changes: [{file_path, edits: [{line, old_text, new_text, confidence}]}]
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.

gitnexus-refactoring is a skill published in the GitHub repository adamkrawczyk/agentpact-mcp-server (0 stars, last pushed 2d ago), licensed MIT. It adds 53 tokens to every session and 1,043 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to gitnexus-refactoring, differing in 58 lines, and is treated as a copy.

code-simplifier
Cleanup pass that edits the working tree — over a session's uncommitted changes, or a named path or whole codebase. Reads git diff (or the named target) and simplifies, consolidates, and aligns code with the existing codebase — modernize syntax, cut unnecessary complexity and slop, consolidate duplicated logic, catch…
gitnexus-impact-analysis
Use when the user wants to know what will break if they change something, or needs safety analysis before editing code. Examples: "Is it safe to change X?", "What depends on this?", "What will break?".
gitnexus-refactoring
Use when the user wants to rename, extract, split, move, or restructure code safely. Examples: "Rename this function", "Extract this into a module", "Refactor this class", "Move this to a separate file".
opik-diagnose
Surface the Opik traces worth a developer's attention, ranked by signal — Diagnostics issues first, then errors, failed tool calls, latency, regressions, and low online-eval scores. With the Opik MCP connected it lists the project's agentinsightsissue entities, offers to turn Diagnostics on when the project has it…
opik-explain
Root-cause a specific Opik trace, or a pattern across traces, and return a grounded explanation. Uses the hosted Opik MCP when it is connected, and falls back to SDK scripting otherwise. Returns the root cause, the evidence spans as clickable Opik UI links, and one suggested next step. Use for "why did this trace…
code-review
Reviews a supplied code path or diff for correctness, security, maintainability, and style without executing or modifying it.
