# Project Constitution Management
## Overview
You are updating the project constitution at `.specify/memory/constitution.md` (or `.specify/.specify/memory/constitution.md` if the user's structure differs). This file is a TEMPLATE containing placeholder tokens in square brackets (e.g. `[PROJECT_NAME]`, `[PRINCIPLE_1_NAME]`). Your job is to (a) collect/derive concrete values, (b) fill the template precisely, and (c) propagate any amendments across dependent artifacts.
**Note**: If the constitution file does not exist yet, it should have been initialized from a template during project setup. If it's missing, copy the template first (check `.specify/templates/constitution-template.md`).
## Execution Flow
1. **Load the existing constitution**.
* 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.
* Otherwise infer from existing repo context (README, docs, prior constitution versions if embedded).
* 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**:
* Check if `.specify/templates/plan-template.md`, `.specify/templates/spec-template.md`, and any other templates align with the updated constitution.
* Update runtime guidance docs (e.g., `README.md`, `docs/quickstart.md`) if they reference changed principles.
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/Removed sections
* Templates requiring updates (✅ updated / ⚠ pending) with file paths
* Follow-up TODOs.
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** back to the file (overwrite).
8. **Output a final summary**:
* 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.
* Wrap long rationale lines to keep readability (<100 chars ideally).
* Keep a single blank line between sections.
* Avoid trailing whitespace.
* If critical info missing, insert `TODO(<FIELD_NAME>): explanation` and include in the Sync Impact Report.
