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 | $0.00424 | $0.00424 |
| Opus 5 | $0.00212 | $0.00212 |
| Sonnet 5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
rafter-cli 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 2d 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
Rafter CLI — Copilot Instructions
Rafter is a security CLI for AI coding agents. It ships as two feature-identical implementations: Node.js (TypeScript) and Python.
Project Rules
- Every change must be made in both Node and Python. A single-language PR is incomplete.
shared-docs/CLI_SPEC.mdis the spec. If CLI behavior changes, update the spec first.- Versions must match between
node/package.jsonandpython/pyproject.toml. - This is a security tool. Minimize dependencies. Never introduce
eval, unsanitized template strings, or command injection vectors. Validate all external input at system boundaries.
Directory Layout
node/src/commands/— CLI commands (commander.js)node/src/core/— Command interceptor, audit logger, config managernode/src/scanners/— Betterleaks integration + regex-based secret scannernode/src/commands/agent/init.ts— Per-platform installation logic (8 platforms)python/rafter_cli/— Mirrors the Node structure with typershared-docs/CLI_SPEC.md— Canonical output contracts and exit codesrecipes/— Copy-paste setup guides per platformvscode/— VS Code extension
Testing
- Node: Vitest (
cd node && pnpm test) - Python: pytest (
cd python && pytest) - Tests must pass in both before merging
Key Patterns
- Commands export a
createXCommand()factory (Node) or use@app.command()decorators (Python) - Scanners use dual-engine: Betterleaks binary first, regex fallback. Patterns defined in
secret-patterns.ts/secret_patterns.py - Risk classification: critical > high > medium > low
- Audit log: JSONL format, append-only, documented schema in CLI_SPEC.md
- MCP server: 4 tools + 3 resources over stdio transport
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.

rafter-cli copilot-instructions.md is an instructions file published in the GitHub repository Raftersecurity/rafter-cli (27 stars, last pushed 4d ago), licensed MIT. It adds 424 tokens to every session, about $0.0021 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 2026-09-04.
