vuestrata: Skill for Claude Code

.github/skills/speckit-constitution/SKILL.md

speckit-constitution is a skill for Claude Code, Codex from boussadjra/vuestrata. It costs 0 tokens per session (114 once invoked), scanned A, original, MIT.

A guide for reviewing or changing a project's constitution, meaning the document that defines its principles and rules for development. It checks proposed changes against those principles.

In plain words
What is it for?
Use it to review current principles, check whether a change follows them, or amend the constitution with justification, a semantic-version update, and an amendment entry.
Why use it?
It makes governance changes traceable and prevents important rules from being weakened without justification. Amendments also receive the required version change and record.

Written for no agent in particular: nothing here depends on one. Also seen: mentions AGENTS.md.

This is boussadjra/vuestrata's own configuration. It tells Claude Code and Codex how to work on vuestrata itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vuestrata configures →

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

speckit-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 24d 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

speckit-constitution Skill

Use to review, check, or amend the project rules in AGENTS.md.

Rules

  1. Read AGENTS.md first. It is the highest authority; there is no separate constitution file.
  2. For review, show the current rules.
  3. For compliance, check the proposed change against each rule.
  4. For amendments, require a justification and make the edit in AGENTS.md itself.
  5. Do not weaken a rule without saying so, and why, in the change's description.
Changes

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.
