iikit-00-constitution

iikit-00-constitution is a skill for Claude Code from intent-integrity-chain/kit. It costs 76 tokens per session (1,353 once invoked), scanned A, original, MIT.

A workflow for creating or updating CONSTITUTION.md, a project document that sets governance rules, coding standards, quality checks, testing policy, and review requirements. TDD, or test-driven development, means writing tests before the implementation they check.

In plain words
What is it for?
Setting project principles, quality gates, TDD requirements, review rules, compliance expectations, and versioned amendments after checking PREMISE.md.
Why use it?
It gives a project a shared set of development rules and records how those rules can be changed.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

Not installable on its own: it runs a file from its repository that does not travel with it. Clone the repository, or install whatever ships that file. The line is bash .tessl/plugins/tessl-labs/intent-integrity-kit/skills/iikit-core/scripts/bash/post-phase.sh --phase 00 --commit-files "CONSTITUTION.md,.specify/context.jso.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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

iikit-00-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 6d ago.

The scan reads SKILL.md. This mod also ships 20 executable files (scripts/bash/common.sh, scripts/bash/generate-dashboard-safe.sh, scripts/bash/next-step.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Intent Integrity Kit Constitution

Process steps in order. Do not skip ahead.

Create or update the project constitution at CONSTITUTION.md — the governing principles for specification-driven development.

Scope

MUST contain: governance principles, non-negotiable development rules, quality standards, amendment procedures, compliance expectations.

MUST NOT contain: technology stack, frameworks, databases, implementation details, specific tools or versions. These belong in /iikit-02-plan. See phase-separation-rules.md.

User Input

$ARGUMENTS

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

Prerequisites Check

  1. Check PREMISE.md exists: test -f PREMISE.md. If missing: ERROR — "PREMISE.md not found. Run /iikit-core init first to create it." Do NOT proceed without PREMISE.md.
  2. Validate PREMISE.md:
    bash .tessl/plugins/tessl-labs/intent-integrity-kit/skills/iikit-core/scripts/bash/validate-premise.sh --json
    
    If FAIL (missing sections or placeholders): ERROR — show details, suggest re-running init.
  3. Check if constitution exists: cat CONSTITUTION.md 2>/dev/null || echo "NO_CONSTITUTION"
  4. If missing, copy from constitution-template.md

Step 1 — Load Existing Constitution

Identify placeholder tokens [ALL_CAPS_IDENTIFIER]. Adapt to user's needs (more or fewer principles than template).

Proceed immediately to Step 2.

Step 2 — Collect Placeholder Values

  • From user input, or infer from repo context
  • RATIFICATION_DATE: original adoption date
  • LAST_AMENDED_DATE: today if changes made
  • CONSTITUTION_VERSION: semver (MAJOR: principle removal/redefinition, MINOR: new principle, PATCH: clarifications)

Proceed immediately to Step 3.

Step 3 — Draft Content

Replace all placeholders, preserve heading hierarchy, ensure each principle has name + rules + rationale, governance section covers amendment/versioning/compliance.

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.
