autospec.constitution

autospec.constitution is a command for Claude Code from ariel-frischer/autospec. It costs 9 tokens per session (1,778 once invoked), scanned A, original, MIT.

A command that creates or updates a project constitution in YAML, a file containing the project's fixed principles and rules for planning and implementation.

In plain words
What is it for?
Use it to establish or revise project principles, governance rules, adoption dates, and related guidance after checking existing project files.
Why use it?
It gives coding agents a shared record of project requirements instead of leaving important decisions scattered across documentation and chat.

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

autospec.constitution 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 10d 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.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Outline

You are creating or updating the project constitution. This file defines the non-negotiable principles and governance rules for the project that all specifications, plans, and implementations must adhere to.

Pre-computed Context

The following values have been pre-computed and are available for use:

  • AUTOSPEC_VERSION: {{.AutospecVersion}}
  • CREATED_DATE: {{.CreatedDate}}

Follow this execution flow:

  1. Load existing context:

    • Check if .autospec/constitution.yaml exists (preferred path)
    • Check if .autospec/memory/constitution.yaml exists (legacy fallback)
    • Check if .autospec/memory/constitution.md exists (for migration)
    • Check if AGENTS.md exists at project root (or agent-specific file like CLAUDE.md as fallback)
    • Extract any existing principles, governance rules, or project guidelines
  2. Collect/derive values:

    • If user input supplies principles, use them
    • Otherwise infer from existing repo context (README, docs, prior constitution)
    • For governance dates:
      • ratified: Original adoption date (if unknown, use today)
      • last_amended: Today if changes are made
    • For versioning: Use semantic versioning
      • MAJOR: Backward incompatible governance/principle changes
      • MINOR: New principle/section added
      • PATCH: Clarifications, wording fixes
  3. Generate constitution.yaml:

    constitution:
      project_name: "<project name>"
      version: "1.0.0"
      ratified: "<YYYY-MM-DD>"
      last_amended: "<YYYY-MM-DD>"

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.
