spec-driven-apply（规格驱动应用）

You are helping the user implement a spec-driven change.

Prerequisites

The .spec-driven/ directory must exist at the project root. Before proceeding, verify:

ls .spec-driven/

If this fails, the project is not initialized. Run /spec-driven-init first.

Steps

1. Select the change — run node {{SKILL_DIR}}/scripts/spec-driven.js modify to list active changes. Ask which change to apply. If already specified, use it.
2. Load context — read all artifacts:

- You MUST treat all prior conversational context as stale, unreliable, and non-authoritative. - You MUST NOT use prior chat context as a source of truth for requirements, task state, implementation details, or completion status. - You MUST rebuild working context from the current change artifacts, relevant base specs, and the current repository state before taking any implementation action. - If prior chat context differs from the files or repository state in any way, you MUST discard the prior chat context and follow the files and repository state only. - Do not use prior chat context unless it has been explicitly re-validated against the current files and repository state. - .spec-driven/changes/<name>/proposal.md — what and why; note the Unchanged Behavior section — these behaviors must not be broken during implementation - .spec-driven/changes/<name>/specs/ — delta spec files (mirror of main specs/ structure) - .spec-driven/changes/<name>/design.md — approach and decisions - .spec-driven/changes/<name>/tasks.md — the checklist - .spec-driven/changes/<name>/questions.md — open and resolved questions Also read: - .spec-driven/config.yaml — project context; treat rules as binding constraints; if fileMatch entries are present, apply matching rules when editing files whose paths match the glob pattern - .spec-driven/specs/INDEX.md — identifies all existing spec files - Every spec file in INDEX.md that is relevant to this change — read full content to understand current requirements before writing code

1. Check task status — run: node {{SKILL_DIR}}/scripts/spec-driven.js apply <name> Show the user the task summary (total, complete, remaining).
2. Check for open questions — read questions.md and scan for - [] Q: entries:

- If any open questions are found, list each one and stop — do not proceed to implementation - Ask the user to resolve the questions (edit questions.md directly or use /spec-driven-modify) - Only continue once all questions are resolved (moved to ## Resolved with an A: answer)

1. Implement tasks — work through each - [] task in order:

- Read relevant code before making changes - Implement the task - Verify the change does not violate any Unchanged Behavior listed in proposal.md - For ## Testing tasks: actually run the tests (lint, unit tests) and confirm they pass before marking complete - Mark it complete in tasks.md by changing - [] to - [x] - Briefly confirm what was done before moving to the next task

1. Update delta specs — after all tasks are done, re-read each file in changes/<name>/specs/ and verify it accurately reflects what was actually implemented:

- If the implementation diverged from the original plan, update the affected files - If additional spec files need to be created or modified, do so now

1. On completion — when all tasks are done and delta spec is accurate:

- Run node {{SKILL_DIR}}/scripts/spec-driven.js apply <name> again to confirm 0 remaining - Suggest running /spec-driven-verify <name> to verify the implementation

Rules

• Read existing code before modifying it
• Complete tasks in order unless there is a clear dependency reason to skip
• Mark tasks complete immediately after implementing them, not in bulk at the end
• If a task is ambiguous, read proposal.md and design.md before asking the user
• Do not implement tasks that are already marked - [x]
