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 | $0.00246 | $0.00246 |
| Opus 5.5 | $0.00098 | $0.00098 |
| Sonnet 5.5 | $0.00049 | $0.00049 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
backlog-mcp-server CLAUDE.md 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 17d 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
backlog-mcp-server
Comments
Keep comments to a minimum. Let names and structure carry the intent, and use a comment only for a "why" that the code cannot show.
Write:
- Security reasons (token leaks, open redirects, SSRF, CSRF, …)
- Behaviour that follows a spec. Cite the RFC or MCP spec section (e.g.
// RFC 9207 — every authorization response carries iss) - Code that is counter-intuitive or breaks if removed
- Workarounds for quirks of external systems (Backlog API, MCP clients, runtimes)
Don't write:
- A restatement of the code, or JSDoc that only repeats the name and types
- History, past implementations or change logs (put them in the commit message and PR)
- Alternatives considered or long reasons for not choosing them (put them in the PR or
docs/) - Narration of what a test does. Say it in the test name
Aim for 1–3 lines. If it turns into a paragraph, it belongs in the PR description or docs/.
When touching existing code, it is fine to remove nearby comments that do not meet this standard.
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.
