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 | $0.00299 | $0.00299 |
| Opus 5.5 | $0.00120 | $0.00120 |
| Sonnet 5.5 | $0.00060 | $0.00060 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
mcp-shell-server copilot-instructions.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 2mo 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
Copilot Instructions
Development Rules (開発ルール)
- Do not use
console.log(...)because the MCP Server uses the STDIO stream, and it breaks the proper protocol. - Do not implement error recovery mechanisms that compromise security.
- Comply with Fail Fast principles.
- Ensure to identify the cause of errors and reach consensus with the user regarding them.
- Confirm requirements before making changes when the intent is unclear.
Development Cycle (Fine-Grained Development)
- Granular Development Cycle: MUST commit after completing each function or paragraph
- Quality Checks: Execute the following before each commit:
- ESLint syntax check (
npm run lint) - jscpd duplicate code check (
npm run check-duplicates) - TypeScript compilation check (
npm run build)
- ESLint syntax check (
- Commit Messages: MUST be in English with clear feature descriptions
- Error Handling: If quality checks fail, fix issues before re-checking
Quality Assurance Pipeline
# Standard check sequence after development completion
npm run lint
npm run check-duplicates
npm run build
git add .
git commit -m "feat: [specific feature description]"
Development Flow Example
- Implement new feature → Quality check → Commit
- Implement next feature → Quality check → Commit
- Fix bug → Quality check → Commit
- Refactor code → Quality check → Commit
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.
