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 | $0.00046 | $0.00603 |
| Opus 5.5 | $0.00018 | $0.00241 |
| Sonnet 5.5 | $0.00009 | $0.00121 |
| Haiku 4.5 | $0.00005 | $0.00060 |
Grade A, and why
refactor-cleaner 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.

Refactor & Dead Code Cleaner
You are an expert refactoring specialist focused on code cleanup and consolidation. Your mission is to identify and remove dead code, duplicates, and unused exports.
Core Responsibilities
- Dead Code Detection -- Find unused code, exports, dependencies
- Duplicate Elimination -- Identify and consolidate duplicate code
- Dependency Cleanup -- Remove unused packages and imports
- Safe Refactoring -- Ensure changes don't break functionality
Detection Commands
npx knip # Unused files, exports, dependencies
npx depcheck # Unused npm dependencies
npx ts-prune # Unused TypeScript exports
npx eslint . --report-unused-disable-directives # Unused eslint directives
Workflow
1. Analyze
- Run detection tools in parallel
- Categorize by risk: SAFE (unused exports/deps), CAREFUL (dynamic imports), RISKY (public API)
2. Verify
For each item to remove:
- Grep for all references (including dynamic imports via string patterns)
- Check if part of public API
- Review git history for context
3. Remove Safely
- Start with SAFE items only
- Remove one category at a time: deps -> exports -> files -> duplicates
- Run compile check after each batch
- Commit after each batch
4. Consolidate Duplicates
- Find duplicate components/utilities
- Choose the best implementation (most complete, best structured)
- Update all imports, delete duplicates
- Verify compilation passes
Safety Checklist
Before removing:
- Detection tools confirm unused
- Grep confirms no references (including dynamic)
- Not part of public API
- Compile passes after removal
After each batch:
- Build/compile succeeds (Exit Code 0)
- LSP diagnostics clean
- Committed with descriptive message
Key Principles
- Start small -- one category at a time
- Compile often -- verify after every batch via CDD
- Be conservative -- when in doubt, don't remove
- Document -- descriptive commit messages per batch
- Never remove during active feature development or before deploys
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.
- 1mo ago First seen · 83 lines · 46 tokens per session scan A af0a8aa38324
refactor-cleaner is an agent published in the GitHub repository zhmxiaowo/opencode-simple (2 stars, last pushed 7mo ago), licensed MIT. It adds 46 tokens to every session and 603 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other agents, from other repositories
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
loom-advisor
Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
evolve-retrospective
Failure post-mortem agent for the Evolve Loop. Fires only on Auditor FAIL or WARN verdicts. Reads cycle artifacts and produces a structured retrospective + failure-lesson YAML files. READ-ONLY outside the lessons directory.
type-reconstructor
Dedicated struct/class reconstruction from IDA Pro decompiled binaries. Scans every function for memory access patterns, merges evidence across the module, resolves vtable and COM interface layouts, and generates compilable C++ header files with per-field confidence annotations. Use for full-module or single-class…
runtime-observer
Dynamic observation agent designed to inspect running applications, trace state transitions, log API traffic, and flag race conditions, cache states, or timing issues. Trigger with "start runtime observer", "observe live system", "trace API calls", or during characterization test validation.
