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 | $0.00019 | $0.00759 |
| Opus 5 | $0.00010 | $0.00380 |
| Sonnet 5 | $0.00004 | $0.00152 |
| Haiku 4.5 | $0.00002 | $0.00076 |
Grade A, and why
debug-tool 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 7d 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.

Debug the tool issue: $ARGUMENTS
Do NOT guess. Trace systematically.
Phase 1 — Identify
- Which tool is affected?
- What is the expected behavior?
- What is the actual behavior? (error message, wrong data, empty response, crash)
Phase 2 — Trace the Request Lifecycle
Read the code for each layer and check for issues:
Layer 1: Tool Schema (src/tools/<category>/<tool>.ts)
- Is
namein the tool definition the same as the routing name inindex.ts? - Does
inputSchemamatch what the handler actually reads fromargs? - Are
requiredfields correctly listed? - Are
enumvalues complete?
Layer 2: Handler Logic
- Is
getApiKey(args)called correctly? - Are required params validated before use?
- Are type conversions correct? (
String(),Number()) - Is the params object passed to the endpoint builder correctly?
Layer 3: Endpoint URL (src/lib/endpoints.ts)
- Is the URL pattern correct? (
/api/mcp/${projectId}/...) - Are query params built correctly?
- Is
projectIdbeing destructured out before building query string? - Log the actual URL being built (add temporary
console.error)
Layer 4: HTTP Request (src/lib/request.ts)
- Is the right HTTP method used? (GET vs POST vs PATCH)
- Is
Content-Type: application/jsonbeing set? - Is the Authorization header present?
- For POST/PATCH: is the body being JSON.stringify'd?
Layer 5: Response Handling
- Does the API return
{ success, data }wrapper or direct data? - Is
response.okbeing checked? - Is the error text being read on failure?
- Is the response being JSON.stringify'd for the MCP return?
Phase 3 — Isolate
Once you've identified the suspect layer:
- Read the specific code carefully
- Check if other tools in the same category work (pattern comparison)
- If the issue is in
endpoints.ts, check the API docs or compare with working tools
Phase 4 — Fix & Verify
- Fix the root cause
- Run
npm run typecheck && npm run lint - If the tool's behavior or params changed, update
docs/TOOLS.md - Remove any temporary
console.errordebug lines
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.

debug-tool is a skill published in the GitHub repository testdino-hq/testdino-mcp (9 stars, last pushed 27d ago), licensed MIT. It adds 19 tokens to every session and 759 once invoked, about $0.0001 per session on Opus 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.
