Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00396 | $0.00396 |
| Opus 5 | $0.00198 | $0.00198 |
| Sonnet 5 | $0.00079 | $0.00079 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade A, and why
HestAI-MCP 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 4d 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 Code Review Instructions
Project Context
HestAI-MCP is a Python MCP server providing context management tools for Claude Code. Stack: Python 3.11+, Pydantic, MCP protocol. Full type hints required.
Review Focus
When reviewing pull requests, prioritise these areas in order:
- Security: Input validation, injection risks, secrets exposure, OWASP Top 10
- Correctness: Logic errors, edge cases, off-by-one, null/None handling
- Type Safety: Missing or incorrect type hints, Pydantic schema mismatches
- Error Handling: Bare excepts, swallowed errors, missing error paths
- Architecture: Coupling, abstraction leaks, violation of existing patterns
Code Standards
- Line length: 100 chars
- Linting: ruff + black
- Type checking: mypy (strict)
- All public functions require docstrings
- Tests in
tests/mirroringsrc/structure
What NOT to Flag
- Do not flag OCTAVE format files (*.oct.md) for markdown issues — these use a domain-specific notation that is intentionally non-standard markdown.
- Do not suggest adding comments to self-explanatory code.
- Do not flag conventional commit message format in PR titles.
- Do not suggest restructuring test files — they mirror src/ by convention.
Governance Files
Files under .hestai-sys/ and .hestai/ are governance/configuration files.
Review these for structural correctness only, not code style.
Severity Guide
- Critical: Security vulnerabilities, data loss risks, broken functionality
- Major: Logic errors, missing error handling, type safety violations
- Minor: Style inconsistencies, naming suggestions, minor improvements
- Nit: Formatting, optional improvements — keep these minimal
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.
