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 | $0.00000 | $0.00257 |
| Opus 5.5 | $0.00000 | $0.00103 |
| Sonnet 5.5 | $0.00000 | $0.00051 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
reuse-check 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.
What it actually says
Reuse Check - Validate Before Creating
Use this command before creating any new files or components to ensure you're not duplicating existing functionality.
Usage: /reuse-check [what you want to create]
Validation Process
MANDATORY REUSE ANALYSIS FOR: $ARGUMENTS
STEP 1: EXHAUSTIVE SEARCH
- Search for existing similar functionality
- Check all relevant directories and files
- Document every related component found
STEP 2: REUSABILITY ASSESSMENT
- Can existing code be extended?
- Can existing patterns be followed?
- Are there utility functions to reuse?
- What architectural constraints exist?
STEP 3: JUSTIFICATION REQUIREMENT If creating new files is necessary, provide:
- Detailed explanation why extension won't work
- Specific architectural reasons for new creation
- Migration strategy from any duplicate functionality
- Integration plan with existing systems
STEP 4: COMPLIANCE CONFIRMATION
- ✓ All existing options explored
- ✓ Extension possibilities exhausted
- ✓ Creation fully justified with specific reasons
- ✓ Follows existing architectural patterns
FINAL DECISION: [EXTEND EXISTING] or [CREATE NEW - JUSTIFIED]
Remember: Creating new files without this analysis violates project rules.
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.

reuse-check is a command published in the GitHub repository vibehat/claude-task-manager (21 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 257 tokens. 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 2026-08-30.
Other commands, from other repositories
review
A code-review command that examines uncommitted changes against the project's plans, architecture, coding principles, tests, and security needs.
refactor
A guided code-refactoring command that changes a chosen module, file, or subsystem while aiming to keep its behavior unchanged.
adversarial-review
Coordinated three-lens adversarial review (chaos + simplifier + adversarial-reviewer) against a PRD, build plan, validation report, code, or proposal — with a fixed must-fix rubric, a mechanical pre-gate, and drift detection on the review itself.
quality-review
Run the 3-agent quality review (simplifier + adversarial-reviewer + chaos-engineer) against a plan, file, or proposal.
adversarial
Run only the adversarial-reviewer (Opus) against a target. Challenges claims and assumptions; finds logical gaps.
simplify
Run only the simplifier (Sonnet) against a target. Finds over-engineering, premature abstraction, and unnecessary indirection.
