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 | $0.00036 | $0.00371 |
| Opus 5.5 | $0.00014 | $0.00148 |
| Sonnet 5.5 | $0.00007 | $0.00074 |
| Haiku 4.5 | $0.00004 | $0.00037 |
Grade A, and why
refactor 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
100% identical to refactor — 646 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.
What it actually says
Refactor
Make the smallest complete change that reduces a demonstrated maintenance problem. Follow AGENTS.md for compatibility, verification, and delivery.
Understand
- Identify the concrete problem and the behavior that must remain unchanged.
- Trace the affected implementation and its callers. Use CodeGraph first when the repository is indexed.
- Inspect existing abstractions, types, and tests before choosing a new structure.
Change
- Reuse existing code and native features before adding abstractions.
- Delete dead code and redundant wrappers. Extract a function or module when it gives a coherent responsibility a useful interface; line count alone is not a reason to split code.
- Keep ownership and dependencies clear. Use
codebase-designwhen the interface itself needs redesign. - Preserve validation, error behavior, side effects, ordering, and public contracts. If the requested work also changes behavior, identify and verify that change explicitly.
- Keep steps reviewable and preserve unrelated working-tree changes. Follow repository delivery rules for commits; each editing step does not require a commit.
Verify
Choose evidence in proportion to the changed behavior and risk. Reuse the existing test framework and run the checks required by the repository.
Add focused characterization coverage when behavior is subtle or insufficiently protected. A mechanical rename or similarly low-risk edit may be proven by typecheck, existing tests, and diff inspection without new tests. When an executable check is unavailable, report the limitation and the evidence actually obtained.
Inspect the final diff for accidental behavior changes, unnecessary abstractions, and incomplete caller migrations. Report what became simpler and how behavior preservation was checked.
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.

refactor is a skill published in the GitHub repository lootlog/monorepo (29 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 371 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to refactor, differing in 646 lines, and is treated as a copy.
