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 | $0.00051 | $0.00603 |
| Opus 5 | $0.00026 | $0.00302 |
| Sonnet 5 | $0.00010 | $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 4d 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-cleaner — 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.

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 tests after each batch
- Commit after each batch
4. Consolidate Duplicates
- Find duplicate components/utilities
- Choose the best implementation (most complete, best tested)
- Update all imports, delete duplicates
- Verify tests pass
Safety Checklist
Before removing:
- Detection tools confirm unused
- Grep confirms no references (including dynamic)
- Not part of public API
- Tests pass after removal
After each batch:
- Build succeeds
- Tests pass
- Committed with descriptive message
Key Principles
- Start small -- one category at a time
- Test often -- after every batch
- 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.

refactor-cleaner is an agent published in the GitHub repository Fmarzochi/EGC (48 stars, last pushed today), licensed Apache-2.0. It adds 51 tokens to every session and 603 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 refactor-cleaner, differing in 0 lines, and is treated as a copy.
Other agents, from other repositories
test-hunter
Generates adversarial tests for a module or feature. Does NOT write happy-path tests — that is the author's job. Finds inputs that break contracts, bypass permissions, trigger race conditions, or violate invariants. Invoke when a module has a base suite and needs adversarial hardening, before merging a sensitive…
change-reviewer
Reviews structural changes (new modules, refactors, schema changes) for architecture conformance, naming conventions, layer violations, and missing ADRs. Invoke when a PR touches architecture, data model, or adds a new domain module.
security-reviewer
Reviews code changes for security issues: credential leaks, auth bypass, missing input validation, unsafe operations, and violations of operation-classification.md. Invoke before merging PRs that touch auth, API routes, or credential handling.
spec-guardian
Verifies the codebase is in sync with the spec (PRD.md, use-cases.md, ADRs, data-model.md). Detects derivation gaps — code that contradicts the spec, spec that has no implementation, and structural decisions without an ADR. Invoke before cutting a release or when drift is suspected.
ijfw-assumptions-analyzer
Use when surfacing hidden assumptions in a brief or plan before execution begins -- what does the plan assume that the spec doesn't guarantee?
default_agents
Reference implementations of default agents designed around different functional focuses and reasoning patterns.
