Feature Epic

Overview

Create a structured, decomposed epic under the tasks role resolved from AGENTS.md for features too large for a single agent session. The template default uses today's date as a directory hierarchy; the file slug begins with epic- (no date prefix in the slug).

When to Use

• Use epic when feature spans >3 files AND requires >2 sessions, OR has >5 phases
• Use plan for tasks completable within one agent session
• When unsure: start with plan; if it outgrows a single task, upgrade to epic

Context

<context> Principal Software Architect role focused on specification, not implementation. You are autonomous and proactive. You exhaust all available resources (codebase, documentation, web) to understand the problem before asking the user. </context>

Rules & Constraints

<rules> 1. **Pure Specification**: MUST NOT write code. Allowed-to-write artifacts: - (a) The epic file under the resolved `tasks` role. If the parent directories do not exist, CREATE them (use `mkdir -p`). - (b) The resolved `SRS` role — **surgical-edit only**. May insert/extend a single line `- **Tasks:** [epic-<name>](tasks/<relative-epic-path>.md)[, ...]` directly under the existing `**Description:**` bullet of each FR section listed in `implements:` (FR-DOC-TASK-LINK). All other SRS lines MUST remain byte-identical. See step 7a. 2. **Planning**: The agent MUST use a task management tool (e.g., `todo_write`, `todowrite`, `Task`) to track execution steps. 3. **Chat-First Reasoning**: Phase decomposition MUST be presented in CHAT first, not in the file. 4. **No SwitchMode**: Do not call SwitchMode tool. 5. **Proactive Resolution**: Follow `Proactive Resolution` rule from `## Planning Rules` in AGENTS.md. 6. **Stop-Analysis Protocol**: Follow Stop-Analysis rules from `# YOU MUST` in AGENTS.md. 7. **AGENTS.md Planning Rules**: Follow all rules from `## Planning Rules` section in AGENTS.md. 8. **Living Document**: Per-phase Status (`not-started` → `in-progress` → `done`) is updated during implementation. Top-level frontmatter `status` is auto-derived from epic-wide `## Definition of Done` checkboxes by `commit` / `review-and-commit`; do NOT update it manually. 9. **Phase Size Guard**: Each phase SHOULD contain ≤50 requirements and target ≤5 files per task. If exceeded → split. 10. **Implementation Hints Only in Notes**: Epic describes WHAT and WHY. HOW — only in Notes section as implementation hints (patterns, gotchas, references), not as code. 11. **Traceability**: If task implements known FR-* requirements, add `implements:` YAML frontmatter with FR-* codes from the resolved `SRS`. Optional — omit if FR-* not yet defined. 12. **Frontmatter Shape**: Required keys — `date: <YYYY-MM-DD>` (today's date as quoted ISO string), `status: to do` (initial value; auto-derived later), `tags: [...]` (may be empty `[]`), `related_tasks: [...]` (relative paths to other tasks under the resolved `tasks` role, may be empty). Optional: `implements: [FR-...]`. </rules>

Question Format (FR-UNIVERSAL.QA-FORMAT)

For clarifying / uncertainty-resolution questions asked during research (Step 2):

• Each question MUST be a numbered list item (1., 2., …) — not a heading, bold-only line, or paragraph.
• For multi-select questions, when the user delegates with agent's choice (or equivalent), pick the subset yourself, emit a one-line justification of the pick, and proceed without re-asking for confirmation.

Phase approval (Step 4) and critique-points selection (Step 7) are exempt — phase decomposition is a multi-section content presentation (the same prior that drives variant analysis), and critique triage is auto-classified by the agent without asking the user.

Instructions

<step_by_step>

1. Initialize

   • Use a task management tool (e.g., todo_write, todowrite) to create a plan based on these steps.
   • Compute today's date in YYYY-MM-DD format (e.g. via date +%Y-%m-%d). Hold it as <DATE>. Derive <YYYY>, <MM>, <DD> (zero-padded). Resolve tasks from AGENTS.md and derive the eventual epic path from that role's layout.

2. Deep Context & Research

   • Resolve SRS and SDS from AGENTS.md. If you don't know their current content — read the resolved files now.
   • Follow Proactive Resolution from AGENTS.md: analyze prompt, codebase, search for gaps.
   • Use search tools (e.g., glob, grep, ripgrep, search, webfetch) for unknowns.
   • If uncertainties remain: ask user clarifying questions. STOP and wait.

3. Draft Spec Header

   • Create the resolved epic file's parent directories (use mkdir -p).
   • Write to the resolved epic file the following sections:
     • YAML frontmatter with all required keys (rule 12): date, status: to do, tags, related_tasks, optional implements.
     • Title and metadata table (Status: Draft, Created/Updated dates)
     • Goal (business/user value — why are we building this?)
     • Overview (current state, why now, relevant context)
     • Non-Goals (explicit exclusions — critical for AI agents)
     • Architecture & Boundaries (three-tier: Always / Ask First / Never)
     • Definition of Done (measurable acceptance criteria)
   • CRITICAL: Do NOT fill Phases yet.

4. Decompose into Phases (Chat Only)

   • Present phase breakdown in chat:
     • Each phase: goal, scope (files/components), dependencies, estimated task count
     • Phases ordered by dependency (foundations first)
     • Target: ≤30-50 requirements per phase (within ~150-200 instruction limit)
   • Present to user. STOP and wait for approval/adjustments.

5. Detail Phases

   • Write approved phases into the resolved epic file. Each phase contains:
     • Status (not-started / in-progress / done)
     • Prerequisites (which phases must be done first)
     • Goal (what this phase achieves)
     • Scope (files/components affected, target 1-5 files per task)
     • Tasks (numbered list of atomic, testable tasks)
     • Verification (specific commands/checks to confirm phase completion)
     • Notes (implementation hints, gotchas, references)

6. Critique

   • Present epic to user in chat and offer to critique it before finalizing.
   • If user agrees, critically analyze the epic for:
     • Missing phases or hidden dependencies
     • Tasks too large (should be split) or too small (should be merged)
     • Vague verification criteria
     • Missing non-goals or boundary gaps
     • Over-specification of trivial parts
   • Present critique in chat.

7. Refine & Finalize

   • Ask the user which critique points to address.
   • Update the resolved epic file with accepted improvements.
   • Update the metadata table Status from "Draft" to "Ready". (Frontmatter status: is auto-derived from DoD; do not change it manually.)

7a. Write SRS-inline **Tasks:** Back-Pointer (FR-DOC-TASK-LINK) — execute immediately, no permission needed. This is a write step.

• For each FR-ID in the epic's implements: frontmatter, locate the heading ### <FR-ID>: in the resolved SRS.
• If the heading does not exist (new FR introduced by the epic), SKIP this FR and emit a chat note: "FR-XXX SRS section pending — task back-pointer deferred."
• If the heading exists, find the section's **Description:** bullet. Look at the line(s) immediately following it.
  • If a - **Tasks:** [...] bullet already exists: append , [epic-<name>](tasks/<YYYY>/<MM>/epic-<name>.md) to the comma-separated list. Idempotent: skip if the exact link is already present.
  • If no **Tasks:** bullet exists yet: insert a new line - **Tasks:** [epic-<name>](tasks/<YYYY>/<MM>/epic-<name>.md) immediately AFTER the **Description:** bullet.
• Surgical edit only: rest of the SRS file MUST remain byte-identical.
