description	Creates or updates the project constitution that defines migration principles, constraints, and conventions. Triggers: "set up constitution", "define migration principles", "create project rules", "establish conventions", "establish migration constitution". NOT for: implementation, implementation planning, task generation.

User Input

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

Mandatory Principles

Outline

You are creating or updating the project constitution to your task's artifact path (the Artifact path: from task metadata). Write constitution.md there. Your job is to (a) collect/derive concrete values, (b) fill the template precisely, and (c) propagate any amendments across dependent artifacts.

Follow this execution flow:

1. Load the existing constitution template at skills/setting-up-constitution/templates/constitution-template.md. Identify every placeholder token of the form [ALL_CAPS_IDENTIFIER].

   IMPORTANT: The user might require less or more principles than the ones used in the template. If a number is specified, respect that - follow the general template. You will update the doc accordingly.

2. Collect/derive values for placeholders:

   • If user input (conversation) supplies a value, use it.
   • If knowledge graph or constitution history contains relevant info, infer from there.
   • Otherwise infer from existing repo context (README, docs, prior constitution versions if embedded).
     • [If exists] Read context.md or similar for any runtime guidance that may inform principle definitions.
   • DO NOT read source code files (.java, .ts, .py, .cs, etc.). Constitution is a high-level governance document. You only need: project structure (directory tree), build files (pom.xml, package.json, build.gradle), config files (application.yml, web.xml), and documentation (README, docs/). If you need to understand the tech stack or architecture patterns, read the top-level build file and directory structure — never individual source files.
   • For governance dates: RATIFICATION_DATE is the original adoption date (if unknown ask or mark TODO), LAST_AMENDED_DATE is today if changes are made, otherwise keep previous.
   • CONSTITUTION_VERSION must increment according to semantic versioning rules:
     • MAJOR: Backward incompatible governance/principle removals or redefinitions.
     • MINOR: New principle/section added or materially expanded guidance.
     • PATCH: Clarifications, wording, typo fixes, non-semantic refinements.
   • If version bump type ambiguous, propose reasoning before finalizing.

3. Draft the updated constitution content:

   • Replace every placeholder with concrete text (no bracketed tokens left except intentionally retained template slots that the project has chosen not to define yet—explicitly justify any left).
   • Preserve heading hierarchy and comments can be removed once replaced unless they still add clarifying guidance.
   • Ensure each Principle section: succinct name line, paragraph (or bullet list) capturing non‑negotiable rules, explicit rationale if not obvious.
   • Ensure Governance section lists amendment procedure, versioning policy, and compliance review expectations.

4. Consistency propagation checklist (convert prior checklist into active validations):

   • Read skills/creating-implementation-plan/templates/plan-template.md and ensure any "Constitution Check" or rules align with updated principles.
   • Read skills/feature-inventory/templates/spec-template.md for scope/requirements alignment—update if constitution adds/removes mandatory sections or constraints.
   • Read skills/breaking-down-tasks/templates/tasks-template.md and ensure task categorization reflects new or removed principle-driven task types (e.g., observability, versioning, testing discipline).
   • Read each command file in skills/*/SKILL.md to verify no outdated references remain when generic guidance is required.
   • Read any runtime guidance docs (e.g., README.md, docs/quickstart.md, or agent-specific guidance files if present). Update references to principles changed.

5. Produce a Sync Impact Report (prepend as an HTML comment at top of the constitution file after update):

   • Version change: old → new
   • List of modified principles (old title → new title if renamed)
   • Added sections
   • Removed sections
   • Templates requiring updates (✅ updated / ⚠ pending) with file paths
   • Follow-up TODOs if any placeholders intentionally deferred.

6. Validation before final output:

   • No remaining unexplained bracket tokens.
   • Version line matches report.
   • Dates ISO format YYYY-MM-DD.
   • Principles are declarative, testable, and free of vague language ("should" → replace with MUST/SHOULD rationale where appropriate).

7. Write the completed constitution to your artifact path (overwrite).

8. Output a final summary to the user with:

   • New version and bump rationale.
   • Any files flagged for manual follow-up.
   • Suggested commit message (e.g., docs: amend constitution to vX.Y.Z (principle additions + governance update)).

Formatting & Style Requirements

• Use Markdown headings exactly as in the template (do not demote/promote levels).
• Wrap long rationale lines to keep readability (<100 chars ideally) but do not hard enforce with awkward breaks.
• Keep a single blank line between sections.
• Avoid trailing whitespace.
• If the user supplies partial updates (e.g., only one principle revision), still perform validation and version decision steps.
• If critical info missing (e.g., ratification date truly unknown), insert TODO(<FIELD_NAME>): explanation and include in the Sync Impact Report under deferred items.
• Do not create a new template; always operate on the existing constitution file at the provided path.
