--- name: ensemble-refine-trd description: Refine and enhance existing TRD with stakeholder feedback and additional detail (Codex skill for /ensemble:refine-trd) user-invocable: true model: high --- # Ensemble Command: /ensemble:refine-trd This Codex skill mirrors the Ensemble slash command `/ensemble:refine-trd`. Follow the workflow below, adapt to the current repository, and keep outputs structured. Refine and enhance an existing Technical Requirements Document based on stakeholder feedback, additional research, or identified gaps. Updates TRD while maintaining version history, traceability, and Design Readiness scoring. ## Workflow ### Phase 1: TRD Review **1. Current TRD Analysis** Review existing TRD content and extract structural metadata - Read the TRD file from the path provided in $ARGUMENTS - Parse frontmatter for Document ID (TRD-YYYY-NNN), Version, PRD reference, Design Readiness Score - Count total tasks (TRD-NNN pattern), total test tasks (TRD-NNN-TEST), total hours estimated - Build dependency graph from [depends: TRD-NNN] annotations - Check if Acceptance Criteria Traceability matrix exists - Note current version number for bumping later - PR format detection: scan TRD for '### PR ' followed by a digit within the '## Master Task List' section (from '## Master Task List' heading to the next '##' heading or EOF). If found: set PR_FORMAT=true and log 'TRD format: PR-stack'. Else: set PR_FORMAT=false and log 'TRD format: legacy phase/sprint'. - If PR_FORMAT=true: count PR boundary sections; for each ### PR N: heading check whether a **Shippable State:** line immediately follows it; record MISSING_SHIPPABLE[N] for any that don't; record INFRA_ONLY_SHIPPABLE[N] for any whose Shippable State text contains only infrastructure language (e.g., 'scaffolding', 'setup done', 'infrastructure complete') with no user-observable capability. **2. Synthesis** After reviewing the TRD, generate a numbered list of findings — do NOT make any edits yet. Scan the TRD for the following categories of issues: - Implementation tasks missing a [satisfies REQ-NNN] annotation - User-facing implementation tasks missing a paired TRD-NNN-TEST task - Missing or incorrect "Validates PRD ACs:" fields (must reference real AC-NNN-M sub-IDs) - [satisfies] annotations that reference non-existent PRD REQ-NNN IDs - Unclear or underspecified implementation details - Missing error handling or recovery mechanism descriptions - Missing performance targets or non-functional requirements - Architecture decisions that are not justified or explained - Integration points or external dependencies that are not fully specified - Tasks with hour estimates >= 8h that should be broken into smaller tasks - Long dependency chains (3+ sequential [depends: TRD-NNN] hops) that create execution bottlenecks - Circular dependencies between tasks - Missing or incomplete Architecture Decision section (should include alternatives with justification) - Missing or outdated Acceptance Criteria Traceability matrix - Missing Design Readiness Gate scorecard in frontmatter - Tasks missing hour estimates entirely - Stale references to files, APIs, or components that no longer exist in the codebase - "(PR_FORMAT=true only) PR sections missing **Shippable State:** annotation — list each ### PR N: heading that lacks an immediately-following **Shippable State:** line" - "(PR_FORMAT=true only) PR sections whose Shippable State describes only infrastructure or scaffolding with no user-observable capability — these must be rewritten or the PR must be split to deliver visible value" - "(PR_FORMAT=true only) Tasks in PR N that [depends: TRD-XXX] where TRD-XXX belongs to PR N+1 or later — forward dependency violates the shippability guarantee of PR N" - "(PR_FORMAT=false only) TRD uses legacy ### Phase N: or ### Sprint N: headings — offer optional conversion to ### PR N: format with Shippable State annotations to enable implement-trd-beads PR-stack mode (present as a low-priority suggestion, not an error)" Use the AskUserQuestion tool to present a consolidated findings list and capture the user's selection. Format the question body exactly as follows: ``` Based on my review of , here are the areas I suggest improving: 1. [issue description — e.g., "TRD-005 is missing [satisfies REQ-NNN] annotation"] 2. [issue description] ...N. [issue description] Which would you like to address? Reply with: all, a comma-separated list of numbers (e.g. 1,3), or skip to exit without changes. ``` Store the user's reply as SELECTED_ITEMS. - If the user replies "skip" or provides no selection, exit immediately without making any changes to the TRD (the workflow is complete). - If the user replies "all", treat every numbered finding as selected. - Otherwise, parse the comma-separated numbers to determine which findings are selected. **3. Interview** Conduct a focused follow-up interview ONLY about the SELECTED_ITEMS from the Synthesis step. Skip any topic the user did not select. Use the AskUserQuestion tool to present questions interactively: - Ask questions ONE AT A TIME (not all at once) - Wait for the user's answer before asking the next question - Do NOT just write questions in your response text - The user should see interactive question UI prompts For each selected finding, ask targeted follow-up questions such as: - For missing [satisfies] annotations: "Which PRD REQ-NNN ID does TRD-XXX satisfy?" - For missing TRD-NNN-TEST tasks: "What acceptance criteria should the test task validate?" - For missing "Validates PRD ACs:" fields: "Which PRD AC sub-IDs does this task validate?" - For unclear implementation details: "Can you clarify how [component] should behave when [scenario]?" - For missing error handling: "What should the system do when [error condition] occurs?" - For missing performance targets: "What is the acceptable latency / throughput / SLA for [operation]?" - For unjustified architecture decisions: "What drove the choice of [technology/pattern]?" - For unspecified integration points: "What contract / protocol / schema does [integration] use?" - For oversized tasks: "TRD-NNN is estimated at Xh. Can we split it into smaller pieces? What are the natural boundaries?" - For dependency chains: "Tasks TRD-AAA -> TRD-BBB -> TRD-CCC -> TRD-DDD form a N-task chain. Can any of these run in parallel?" - For missing architecture decisions: "What alternatives were considered for [component] and why was this approach chosen?" - For stale references: "TRD-NNN references [path/file] which no longer exists. Should this task be updated or removed?" - "For missing Shippable State (PR_FORMAT=true): 'PR N has no Shippable State annotation. In one sentence, what user-observable capability exists after this PR merges? (not infrastructure — a feature, endpoint, or UI state a user can interact with)'" - "For infrastructure-only Shippable State (PR_FORMAT=true): 'The current Shippable State for PR N reads: \"\". This describes infrastructure, not user-observable behaviour. What does a user gain when this PR is live?'" - "For forward dependency violations (PR_FORMAT=true): 'TRD-XXX in PR N depends on TRD-YYY in PR N+1. This breaks PR N shippability. Should we move TRD-XXX to PR N+1, or can TRD-YYY be moved to PR N?'" - "For legacy format conversion offer (PR_FORMAT=false): 'This TRD uses ### Phase N: headings. Would you like to convert the Master Task List to ### PR N: format with Shippable State annotations? This enables implement-trd-beads PR-stack mode (feature/-pr-N branches, per-PR git town propose). The ## Sprint Planning section would remain unchanged.'" **4. Feedback Integration** Incorporate stakeholder feedback collected during the interview into a change plan - Apply interview answers to the relevant findings in SELECTED_ITEMS only - For new tasks added, assign next sequential TRD-NNN ID - For split tasks, preserve original [satisfies] annotations on child tasks - For dependency changes, update the dependency graph and check for new circular deps - Compile a change plan summarizing all modifications to be applied ### Phase 2: Enhancement **1. Content Refinement** Apply changes ONLY for the SELECTED_ITEMS identified in the Synthesis step. Do not alter sections that were not selected by the user. Enhancements to apply (scoped to selected findings): - Add [satisfies REQ-NNN] annotations to implementation tasks that lack them - Add missing TRD-NNN-TEST paired tasks for user-facing implementation tasks - Validate and correct "Validates PRD ACs:" fields to reference real PRD AC sub-IDs (AC-NNN-M) - Ensure all [satisfies] annotations reference real PRD REQ-NNN IDs - Expand unclear implementation details with specifics gathered during the interview - Add error handling and recovery mechanism descriptions where missing - Add performance targets and non-functional requirement entries where missing - Document justifications for architecture decisions - Specify integration contracts, protocols, and schemas for external dependencies - Break oversized tasks (>= 8h) into smaller subtasks per interview guidance - Restructure dependency chains to enable parallel execution where possible - Remove or update stale file/API/component references - Add or complete Architecture Decision section with alternatives and justification - "(PR_FORMAT=true) Add missing **Shippable State:** lines: insert immediately after each ### PR N: heading that lacks one, using the user's interview answer" - "(PR_FORMAT=true) Rewrite infrastructure-only Shippable State lines with user-observable capability from interview answers" - "(PR_FORMAT=true) Resolve forward dependency violations: move affected tasks to the correct PR section per interview guidance; re-verify ordering after moving" - "(PR_FORMAT=true) When inserting new tasks, place them inside the correct ### PR N: section based on their dependencies — do not add tasks between PR sections or above the first ### PR N: heading" - "(PR_FORMAT=false, user confirmed conversion) Convert ### Phase N: / ### Sprint N: headings in the Master Task List to ### PR N: format; add a **Shippable State:** line for each (gathered via interview); leave ## Sprint Planning section unchanged — it uses H2 headings and is informational only" **2. Validation** Verify structural integrity of the refined TRD before writing - Verify all TRD-NNN IDs are unique and sequential - Verify all [satisfies REQ-NNN] annotations reference valid PRD requirements - Verify all [depends: TRD-NNN] annotations reference existing tasks - Check no circular dependencies were introduced - Verify all user-facing implementation tasks have paired TRD-NNN-TEST tasks - Count tasks and hours to verify they haven't drifted from the Master Task List summary - If PR_FORMAT=true: verify every ### PR N: heading in the Master Task List has an immediately-following **Shippable State:** line - If PR_FORMAT=true: verify no task has a [depends: TRD-XXX] where TRD-XXX belongs to a later PR section (no forward dependencies across PR boundaries) - If PR_FORMAT=true: verify the Master Task List section contains only ### PR N: headings (no mixed ### Phase N: or ### Sprint N: headings) ### Phase 3: Design Readiness Gate Re-Score **1. Re-Score Readiness Dimensions** Re-evaluate the Design Readiness Gate after refinement changes - Score architecture completeness (1-5): are all components, interfaces, and data flows defined? - Score task coverage (1-5): does every REQ-NNN have implementation and test tasks? - Score dependency clarity (1-5): are dependencies explicit and acyclic? - Score estimate confidence (1-5): are estimates consistent, reasonable, and granular enough? - Compute overall score: average of all four dimensions **2. Compare With Previous Score** Compare new readiness score against the previous score from frontmatter - Read previous Design Readiness Score from TRD frontmatter - Print delta: 'Design Readiness: X.X -> Y.Y (improved/declined/unchanged)' - If score dropped, warn the user and explain which dimensions declined - If no previous readiness score exists, offer to run the gate for the first time **3. Assess Team Impact** Determine whether task changes warrant team reconfiguration - Calculate task count delta (original vs refined) - Calculate hour estimate delta (original vs refined) - If task count changed by >20%, suggest: '/ensemble:configure-team to re-configure the team' - Update the readiness score in frontmatter ### Phase 4: Output Management **1. TRD Update** Write the refined TRD with version history and changelog - Bump version in frontmatter (increment patch: e.g. 1.0.0 -> 1.0.1) - Refresh the Acceptance Criteria Traceability matrix (recalculate from current task annotations) - Add changelog entry at the bottom: date, version, list of changes made - Save the updated TRD to the same file path (overwrite) - Print summary: changes made, new version, task count delta, hour estimate delta ## Expected Output **Format:** Refined Technical Requirements Document (TRD) **Structure:** - **Updated TRD**: Enhanced TRD with feedback incorporated - **Version History**: Changelog of updates and refinements - **Acceptance Criteria Traceability**: Updated matrix linking PRD requirements to TRD implementation and test tasks - **Design Readiness Scorecard**: Re-scored readiness dimensions with delta comparison (if applicable) - **Changelog Entry**: Dated version entry listing all changes made during refinement - **Configure-Team Suggestion**: Recommendation to re-run /ensemble:configure-team if task changes exceed 20% delta ## Usage ``` /ensemble:refine-trd ```
