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 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.
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.

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 dalmasonto/umbral (14 stars, last pushed 9d ago), licensed Apache-2.0. 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.
