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 | $0.00011 | $0.00725 |
| Opus 5.5 | $0.00004 | $0.00290 |
| Sonnet 5.5 | $0.00002 | $0.00145 |
| Haiku 4.5 | $0.00001 | $0.00072 |
Grade A, and why
verify-claim 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 12d 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.

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CRITICAL: Verify before implementing
Before making ANY code changes, verify the following using available tools:
File Existence
- Use #tool:search/codebase to confirm files exist at claimed paths
- Use #tool:search to verify functions/classes mentioned exist
- List actual files that will be modified with full paths
Pattern Verification
- Search for similar existing patterns in the codebase
- Confirm the approach matches existing conventions
- Verify imports/dependencies are already used elsewhere
API/Framework Usage
- If using a framework method, search codebase for examples
- Verify the API signature matches what you're claiming
- Don't assume methods exist - find evidence first
Dependencies
- Check package.json / requirements.txt / go.mod for existing dependencies
- Don't suggest adding dependencies unless verified they're needed
- Search if functionality already exists in codebase
Report Format
✅ Verification Complete:
- Files exist: [list]
- Patterns found: [examples from codebase]
- Dependencies present: [list]
- Similar implementations: [file:line references]
⚠️ Concerns:
- [Any gaps or uncertainties]
Ready to proceed: Yes/No
Only proceed if verification passes.
**Usage**: Type `/verify` before asking agent to implement complex features

## 4. Recommended Workflow
### Option A: Full Workflow (Complex Features)
- Planner Agent: "Plan a feature for [description]"
- Review plan mentally or with /review
- Builder Agent: "Implement the plan above"
- Builder hands off → Reviewer Agent (automatic via handoff)
- Fix issues if needed
### Option B: Quick Implementation (Simple Tasks)
- Builder Agent: "Add [simple feature]"
- /review after completion
### Option C: Verification First (Uncertain Tasks)
- /verify the approach first
- Builder Agent: implement after verification passes
- /review after completion

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.

verify-claim is a command published in the GitHub repository rapozoantonio/memorykit (4 stars, last pushed 13d ago), licensed MIT. It adds 11 tokens to every session and 725 once invoked, about $0.0000 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 2026-10-17.
