Check for extension hooks (before constitution update):

condition field, or it is null/empty, treat the hook as executablecondition, skip the hook and leave condition evaluation to the HookExecutor implementation.) with hyphens (-). For example, speckit.git.commit → /speckit-git-commit.optional flag:

Wait for the result of the hook command before proceeding to the Outline..specify/extensions.yml does not exist, skip silentlyYou are updating the project constitution at .specify/memory/constitution.md. 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 .specify/memory/constitution.md does not exist yet, it should have been initialized from .specify/templates/constitution-template.md during project setup. If it's missing, copy the template first.
Follow this execution flow:
Load the existing constitution at .specify/memory/constitution.md.
[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.Collect/derive values for placeholders:
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:
Draft the updated constitution content:
Consistency propagation checklist (convert prior checklist into active validations):
.specify/templates/plan-template.md and ensure any "Constitution Check" or rules align with updated principles..specify/templates/spec-template.md for scope/requirements alignment—update if constitution adds/removes mandatory sections or constraints..specify/templates/tasks-template.md and ensure task categorization reflects new or removed principle-driven task types (e.g., observability, versioning, testing discipline)..specify/templates/commands/*.md (including this one) to verify no outdated references (agent-specific names like CLAUDE only) remain when generic guidance is required.README.md, docs/quickstart.md, or agent-specific guidance files if present). Update references to principles changed.Produce a Sync Impact Report (prepend as an HTML comment at top of the constitution file after update):
Validation before final output:
Write the completed constitution back to .specify/memory/constitution.md (overwrite).
Output a final summary to the user with:
docs: amend constitution to vX.Y.Z (principle additions + governance update)).Formatting & Style Requirements:
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 .specify/memory/constitution.md file.
Check for extension hooks (after constitution update):
Check if .specify/extensions.yml exists in the project root.
