Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

SpecPilot 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.

AI Coding Instructions — SpecPilot

This file is automatically read by GitHub Copilot, Cursor, and other AI tools on every request. Keep this file short — only critical mandates. Full context is in .specs/project/project.yaml.

Project

  • Name: SpecPilot
  • Stack: TypeScript / Node.js / Commander.js
  • Specs location: .specs/

🔴 Critical Mandates — Never violate, no exceptions

  1. NEVER commit code to git unless the developer explicitly asks. Always ask first.
  2. NEVER push to git unless the developer explicitly asks. Always ask first.
  3. NEVER deploy, publish, or release the project unless the developer explicitly asks. Always ask first.
  4. NEVER modify the .specs/ folder structure, subfolder names, or file names. Only update file contents.
  5. ALWAYS update affected .specs/ files after every code change — without being asked:
    • Structural changes → architecture/architecture.md
    • Feature changes → project/requirements.md
    • Test changes → quality/tests.md
    • Task status → planning/tasks.md
    • Completed work → CHANGELOG.md
  6. NEVER describe, quote, or reference file contents without first reading the file via a tool call in this session. If you have not read the file yet, say so explicitly before answering.
  7. NEVER implement, write code, or make file changes unless the developer explicitly asks. If the next step seems obvious, ask first — do not assume.
  8. SPEC-FIRST review gate: Before touching any code or non-spec files, read all relevant .specs/ files, update all affected spec files first, present a Spec Report summarizing what changed, which files were affected, and what the specs now say, then wait for the developer's explicit yes, proceed before writing code. If the developer declines, revert the spec changes and stop.

🟡 Process Mandates

  • Spec-First: Update .specs/ before writing code.
  • Log all AI interactions in .specs/development/prompts.md with timestamps.
  • Document decisions in .specs/development/context.md.

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.
