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 | $0.00053 | $0.00962 |
| Opus 5 | $0.00026 | $0.00481 |
| Sonnet 5 | $0.00011 | $0.00192 |
| Haiku 4.5 | $0.00005 | $0.00096 |
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 yesterday.
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
100% identical to gitnexus-refactoring — 0 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. impact({target: "X", direction: "upstream"}) → Map all dependents
2. query({search_query: "X"}) → Find execution flows involving X
3. context({name: "X"}) → See all incoming/outgoing refs
4. Plan update order: interfaces → implementations → callers → tests
If "Index is stale" → run
node .gitnexus/run.cjs analyzein terminal.
Checklists
Rename Symbol
- [ ] rename({symbol_name: "oldName", new_name: "newName", dry_run: true}) — preview all edits
- [ ] Review graph edits (high confidence) and text_search edits (review carefully)
- [ ] If satisfied: rename({..., dry_run: false}) — apply edits
- [ ] detect_changes() — verify only expected files changed
- [ ] Run tests for affected processes
Extract Module
- [ ] context({name: target}) — see all incoming/outgoing refs
- [ ] impact({target, direction: "upstream"}) — find all external callers
- [ ] Define new module interface
- [ ] Extract code, update imports
- [ ] detect_changes() — verify affected scope
- [ ] Run tests for affected processes
Split Function/Service
- [ ] context({name: target}) — understand all callees
- [ ] Group callees by responsibility
- [ ] impact({target, direction: "upstream"}) — map callers to update
- [ ] Create new functions/services
- [ ] Update callers
- [ ] detect_changes() — verify affected scope
- [ ] Run tests for affected processes
Tools
rename — automated multi-file rename:
rename({symbol_name: "validateUser", new_name: "authenticateUser", dry_run: true})
→ 12 edits across 8 files
→ 10 graph edits (high confidence), 2 text_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 GrayCodeAI/starling (2 stars, last pushed 2d ago), licensed MIT. It adds 53 tokens to every session and 962 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to gitnexus-refactoring, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
ccc
This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the…
mb-ads
Create and review ads, and prepare provider-safe launch plans/checks. Flexible entry points: full pipeline (copy + images), copy only, images only, creative variations (hook library), video scripts, long-form video ads/VSL-style paid creative, video repurpose, compliance review, launch-plan, instrumentation, check, or…
mb-think
Combined research, decision, and codification workflow. Use when: (1) Exploring a question before committing (2) Making a decision that needs documentation (3) User says research, decide, figure out, explore, codify, enrich, retire stale source, sharpen this offer, improve the offer, add context, keyword gate, analyze…
mb-end
Session-closing skill that helps users wrap up intentionally. Use when: user says done, wrapping up, end my day, closing out, call it a day, goodnight, that's it for today, checkpoint, pause. Bookend to /mb-start. Scans git activity, surfaces what happened, spawns a crystallize agent for deep analysis, offers to save…
mb-organic
CREATE organic content scripts (Reels, TikTok, carousels, static posts) and repurpose sales videos/VSLs into short clips or creator-style excerpts. Use when user wants to GENERATE new scripts from concepts or make short clips from a sales video. NOT for research/mining competitor content - that's /mb-think. NOT for…
mb-setup
Bootstrap a new business folder with Main Branch structure, or migrate an existing single-offer folder to multi-offer. Use when: (1) New user needs Claude Code environment configured (2) User says "set up", "get started", "initialize", "bootstrap", "create my repo", "new business" (3) User is new to Main Branch and…
