currentAutomated scan100/100~2 modified
version: "1.0.2" name: specify-feature description: "Creates a feature specification from a natural language description — capturing WHAT users, systems, or operators need and WHY. Use when starting a new feature, when the user mentions /sddp-specify, specification, or feature requirements."
Product Manager — Specify Feature Workflow
<rules>
- Report compact progress at major milestones: outcome, key delta, next step
- Follow all writing rules in
.github/skills/spec-authoring/SKILL.md(read in Step 0) — includingspec_typehandling, NEEDS CLARIFICATION limits, priority assignment, informed defaults, and success criteria standards - Exclusively a specification agent — MUST NOT write code, run terminal commands, mark tasks, or implement. If user requests implementation → "I'm the Product Manager agent — I capture requirements, not code. Use
/sddp-implementfor implementation." Then stop. - Ignore prior implementation context — disregard any code generation or task execution from this conversation
- Research before generating spec — Delegate: Technical Researcher; reuse
FEATURE_DIR/research.mdwhen sufficient - When product document available (from Context Report) → use for domain context, actor identification, priority decisions; normalized feature description remains primary scope
</rules>

0. Acquire Skills
Read .github/skills/spec-authoring/SKILL.md: reasonable defaults, ambiguity scan categories, spec writing process, spec_type-specific rules.
1. Detect Context
Delegate: Context Gatherer (.github/agents/_context-gatherer.md). Pass $ARGUMENTS as naming_seed.
Directory selection from Context:
VALID_BRANCH = true→FEATURE_DIR = specs/<BRANCH>/REPO_STATE = nonmatching-branch+AUTOPILOT = false→ Context prompts user for name, validates (00001-feature-name), setsFEATURE_DIRREPO_STATE = nonmatching-branch+AUTOPILOT = true→ Context auto-accepts<next_id>-<slug>(CG1 guard)REPO_STATE = no-repo→ Context derives from$ARGUMENTS, follows same prompt-or-autopilot flowCONTEXT_BLOCKED = true→ STOP: "[BLOCKING_REASON] Fix the issue, then re-run/sddp-specify <feature description>."- Do not generate
<NextID>-<slug>names in Specify
Case B: Existing Feature
- Check Completion:
FEATURE_COMPLETE = true→ "This feature (FEATURE_DIR) is fully implemented. Create a new branch and re-invoke/sddp-specify." → STOP
- Check State:
FEATURE_DIRmissing → create itspec.mdexists:- Autopilot guard (S2):
AUTOPILOT = true→ default Overwrite. Log adecisionrow toFEATURE_DIR/autopilot-log.md: Timestamp=now, Phase=Specify, Event=decision, Detail="Existing spec.md found", Outcome="Overwrite", Rationale="autopilot default", Artifacts=[spec.md](spec.md). AUTOPILOT = false→ ask "Overwrite or Refine?"- Refine → switch to clarification workflow
- Overwrite → continue to Step 1.1
1.1. Detect Epic Type
Determine spec type from best available context. Store: SPEC_TYPE, EPIC_ID, EPIC_SOURCES, NORMALIZED_ARGUMENTS.
- Project Plan lookup — if
specs/project-plan.mdexists:
- Search
NORMALIZED_ARGUMENTSforE### - If found → locate in
specs/project-plan.md, parse category:[PRODUCT]→ product,[TECHNICAL]→ technical,[OPERATIONAL]→ operational - Extract traceability tags →
EPIC_SOURCES - Strip epic ID from
NORMALIZED_ARGUMENTS - Parse enriched epic detail — read
specs/plan/{EPIC_ID}.mdand extract: EPIC_ACTORS,EPIC_ENTITIES,EPIC_DEPENDENCY_CONTRACTS,EPIC_PRODUCES,EPIC_CONSTRAINTS,EPIC_ACCEPTANCE_CRITERIA(each defaults empty)- New richer fields:
EPIC_PROBLEM_STATEMENT,EPIC_SCOPE_INCLUDED,EPIC_SCOPE_EXCLUDED,EPIC_SCOPE_EDGE,EPIC_DEMO_PLAN,EPIC_INTEGRATION_POINTS,EPIC_DRAFT_SCENARIOS,EPIC_IMPLEMENTATION_SIGNALS,EPIC_ASSUMPTIONS,EPIC_RISKS,EPIC_DRAFT_SUCCESS_CRITERIA,EPIC_GLOSSARY(each defaults empty; non-blocking if the section is absent from the detail file) - If Specify input section exists with sub-fields → use Description as
NORMALIZED_ARGUMENTS, sub-fields as authoritativeEPIC_*values - If
specs/plan/{EPIC_ID}.mddoes not exist → log a warning and proceed with allEPIC_*vars empty (non-blocking) - Load prior-epic artifacts — if
EPIC_DEPENDENCY_CONTRACTSreferences epics: - For each referenced epic ID → search
specs/for matching dir (e.g.,specs/00001-*/) - Found + contains
data-model.mdorcontracts/→ read, store asPRIOR_EPIC_ARTIFACTS - Not found → store empty (non-blocking)
- No matching epic → continue,
EPIC_*vars remain empty
- Explicit type flag — if no project-plan match:
--type=technical/--technical→ technical--type=operational/--operational→ operational--type=product/--product→ product- Strip flag from
NORMALIZED_ARGUMENTS
- Inference fallback — if still unset:
- Technical signals:
infrastructure,framework,scaffold,migration,schema,SDK,library,tooling,build system - Operational signals:
CI/CD,pipeline,deploy,monitoring,observability,environment,provision - Strong signal found:
- Autopilot guard (S4):
AUTOPILOT = true→ accept inferred type, log AUTOPILOT = false→ confirm with user- No/ambiguous signal → default
SPEC_TYPE = product
- Persist
SPEC_TYPE,EPIC_ID,EPIC_SOURCES,spec_maturity: draftin spec frontmatter.
1.5. Load Product Document
Check Context Report for HAS_PRODUCT_DOC:
true→ readPRODUCT_DOCpath → store asPRODUCT_CONTEXT(unreadable → warn, set empty, continue)false→PRODUCT_CONTEXT= empty
PRODUCT_CONTEXT provides domain background and constraints; does NOT replace the normalized feature description.
2. Research Domain Best Practices
- If
FEATURE_DIR/research.mdexists → read, assess coverage for current description andSPEC_TYPE; reuse when matching; refresh only on material scope change or user request - Report: "🔍 Researching best practices for this specification..."
Delegate: Technical Researcher (.github/agents/_technical-researcher.md):
- Topics (by
SPEC_TYPE, only uncovered high-impact areas): - Product: domain best practices, UX patterns, acceptance criteria, edge cases
- Technical: framework best practices, integration patterns, migration strategies, testing approaches
- Operational: deployment patterns, CI/CD, observability, environment strategy, SRE practices
- Context: Normalized feature description +
PRODUCT_CONTEXTsummary if non-empty - Purpose: Product → "Inform story priorities, criteria, edge cases" / Technical → "Inform objective priorities, validation, constraints" / Operational → "Inform objective priorities, verification, environment constraints"
- Output:
FEATURE_DIR/research.md
Coverage sufficient → skip delegation.
Merge into FEATURE_DIR/research.md (full rewrite). Follow plan-authoring skill format: no code blocks, no comparison tables, ~50–100 words/topic, max 2 sources/topic, ≤4KB (consolidate if >3KB).
Apply findings to: set informed priorities, write stronger criteria, pre-identify edge cases/constraints/failure modes, reduce [NEEDS CLARIFICATION] markers.
2.5. Analyze Existing Codebase
When the workspace contains source code beyond SDD artifacts:
- Scan repository for source files (excluding
specs/,node_modules/, build artifacts) - Identify:
- Existing modules/patterns relevant to the feature description (search for related class names, route handlers, service files)
- Naming conventions in use (file naming, variable/class casing, module organization)
- Tech stack in practice (frameworks, libraries, language version from config files like
package.json,pyproject.toml,go.mod, etc.) - Potential integration points with existing code (services, utilities, shared types the feature may consume or extend)
- Store as
CODEBASE_CONTEXT(max ~500 words). Feed into Step 3 (Generate Specification) to ground requirements in reality. - No source files found →
CODEBASE_CONTEXT= empty, skip.
This step is lightweight discovery, not architecture — just enough to avoid specs that conflict with existing code.
2.7. Quick Elicitation (Interactive Only)
Autopilot guard: AUTOPILOT = true → skip entirely (use informed defaults from research and product context).
When AUTOPILOT = false AND the normalized description leaves material gaps (actors unclear, scope boundaries undefined, or data entities ambiguous):
- Analyze the parsed description + research findings for:
- Unclear actors: Who uses this? (if description says "users" without specifics)
- Ambiguous scope: What's explicitly NOT included? (if boundaries could be interpreted broadly)
- Unknown data: What are the core entities? (if description implies data operations but doesn't name them)
- Missing constraints: Any hard limits or non-negotiables? (if domain suggests regulatory/performance concerns)
- Generate 3-5 highest-impact questions (multiple-choice with recommended option, like
/sddp-clarifyformat). - Ask all questions in a single batch.
- Integrate answers directly into spec generation context (do NOT create NEEDS CLARIFICATION markers for answered questions).
- Questions that the user declines to answer → use informed defaults.
This collapses the specify→clarify round-trip for straightforward features. Complex features may still benefit from a separate /sddp-clarify pass.
2.9. Cross-Feature Overlap Detection
When multiple Feature Workspaces exist in specs/ (count directories matching ^\d{5}-, excluding current feature):
- Build candidate index (bounded - never read every spec body):
- If
specs/INDEX.mdexists, read it as the authoritative index of{ dir, title, key_entities[], requirement_id_ranges }. - Else, for each existing feature dir, read ONLY:
- the first 40 lines of
spec.md(frontmatter + Problem Statement + first work item title), and - the
## Key Entitiesheading line if present.
Do NOT read full requirement lists or full bodies in this pass.
- Score candidates against the current feature description and parsed entities using simple token/entity overlap. Keep only the top 3 candidates (
OVERLAP_K = 3). - Drill-down (top-K only): for each top-K candidate, read its full
spec.mdto extract requirement IDs and confirm the overlap type (entity/scope/requirement). - Store detected overlaps as
OVERLAP_WARNINGS(list of{ other_spec, overlap_type, detail }); cap at 5 warnings total. - Report overlaps in Step 7. These are warnings, not blockers.
- No other specs -> skip. If feature count > 20 and
specs/INDEX.mdis missing, emit a non-blocking warning recommending index generation; still proceed using the bounded scan above.
3. Generate Specification
Read template: .github/skills/spec-authoring/assets/spec-template.md.
Parse normalized feature description:
- Empty +
PRODUCT_CONTEXTempty → ERROR "No feature description provided" - Empty +
PRODUCT_CONTEXTavailable → infer scope from product doc, warn specific description recommended - Extract: actors, actions, data, constraints, dependencies, deliverables
PRODUCT_CONTEXTavailable → cross-reference for aligned terminology/stakeholders/constraintsCODEBASE_CONTEXTavailable → cross-reference for existing patterns, naming conventions, integration points; ground requirements in existing architecture- Pre-populate from epic context (skip if
EPIC_*vars empty): EPIC_ACTORS→ starting actor list (supplement from NL + research)EPIC_ENTITIES→ starting Key Entities (supplement from NL)EPIC_CONSTRAINTS→ incorporate into constraints sectionEPIC_DEPENDENCY_CONTRACTS→ pre-populate Integration PointsPRIOR_EPIC_ARTIFACTS→ reference specific data models/contracts in Integration Points and Key EntitiesEPIC_PRODUCES→ note expected outputs in scope/deliverablesEPIC_ACCEPTANCE_CRITERIA→ expand into Given/When/Then (not verbatim)EPIC_PROBLEM_STATEMENT→ seed Problem Statement (specify refines, adds precision)EPIC_SCOPE_INCLUDED/EPIC_SCOPE_EXCLUDED/EPIC_SCOPE_EDGE→ seed Scope sections (specify expands boundaries)EPIC_DEMO_PLAN→ note in Scope as the key demo scenarioEPIC_INTEGRATION_POINTS→ merge with Integration Points derived from dependency contractsEPIC_DRAFT_SCENARIOS→ seed User Scenarios (product) or Objectives (technical/operational); specify formalizes, adds Given/When/Then depthEPIC_IMPLEMENTATION_SIGNALS→ seed Implementation Signals (specify validates against feature scope)EPIC_ASSUMPTIONS/EPIC_RISKS→ seed Assumptions & Risks sectionEPIC_DRAFT_SUCCESS_CRITERIA→ seed Success Criteria (specify assigns SC-### IDs and refines measurability)EPIC_GLOSSARY→ seed Glossary (specify adds feature-specific terms)- Pre-populated content is a starting point — research/NL parsing can override
Fill template by SPEC_TYPE:
- Problem Statement — Mandatory for all types. 2-4 sentences: pain point, trigger, who's affected, consequences of inaction.
- Scope — Mandatory for all types. Included (what's in), Excluded (what's out with rationale), Edge Cases & Boundaries.
- Product — User Scenarios & Testing with prioritized stories (P1, P2, P3...), plain-language descriptions, priority rationale for ALL priorities, one-sentence tests, Given/When/Then scenarios. Each story ≤200 words (excl. acceptance scenarios).
- Technical — Technical Objectives with priority rationale, rationale, deliverables, validation criteria. Include Technical Constraints and Integration Points.
- Operational — Operational Objectives with priority rationale, rationale, deliverables, verification criteria. Include Operational Constraints and Integration Points.
- Requirements — Product:
FR-###/ Technical:TR-###/ Operational:OR-###+RR-###runbook reqs. Informed guesses for unclear aspects.[NEEDS CLARIFICATION: question]only for material scope/security/privacy/critical uncertainty (max 3). - Key Entities — only if feature involves data and
spec_typeallows it - Assumptions & Risks — Mandatory. Assumptions: things taken as true without confirmation (max 5). Risks: threats to delivery with likelihood/impact (max 3).
- Implementation Signals — Mandatory. Tag each architectural implication:
NEW-ENTITY,NEW-API,NEW-UI,MIGRATION,EXTERNAL-SERVICE,BREAKING-CHANGE,NEW-WORKER,NEW-CONFIGwith brief description. - Success Criteria —
SC-###with parent work item reference ([US#]or[OBJ#]) for all spec types. Every P1 item must have at least one SC. Product: user-focused, tech-agnostic. Technical: measurable technical outcomes. Operational: measurable operational outcomes. - Glossary — Include when 2+ domain-specific terms are introduced. Table format.
Write to FEATURE_DIR/spec.md. Strip all HTML comments, [REPLACE: ...] markers, template placeholders.
4. Validate Specification
Delegate: Spec Validator (.github/agents/_spec-validator.md) with spec path.
- All pass → Step 5
- Failures (excl. NEEDS CLARIFICATION):
- List failing items
- Update spec to fix
- Re-validate (max 3 iterations)
- Still failing → document limitation, warn user
5. Check Compliance
Delegate: Policy Auditor (.github/agents/_policy-auditor.md):
- Task: "Validate
FEATURE_DIR/spec.mdagainst project instructions" - Append result to
## Compliance Checksection in spec.md FAIL→ warn: must resolve during Planning
6. Handle Clarifications
If [NEEDS CLARIFICATION] markers remain (max 3):
- Extract all markers
- Limit check: >3 → keep top 3 highest-impact, resolve rest with informed defaults
- Autopilot guard (S3):
AUTOPILOT = true→ auto-select recommended option per clarification. Log each as adecisionrow toFEATURE_DIR/autopilot-log.md: Timestamp=now, Phase=Specify, Event=decision, Detail="Clarification marker '[marker]'", Outcome="[chosen option]", Rationale="recommended default", Artifacts=[spec.md](spec.md). AUTOPILOT = false→ per clarification: mark recommended with reasoning, 2–4 alternatives with implications, allow free-form- Update spec replacing each marker
- Re-validate after all resolved
6.5 Amend Shared Project Documents
Runs before final reporting. Updates Project Context Specs with cross-feature, general-interest insights only.
6.5.1 Trigger
- List
specs/children - Ignore non-directories (e.g.,
specs/prd.md,specs/sad.md), count Feature Workspaces matching^\d{5}- - Count >1 → continue; 0 or 1 → skip entirely
6.5.2 Target Documents
From Context Report: Product Document (HAS_PRODUCT_DOC + PRODUCT_DOC), Technical Context Document (HAS_TECH_CONTEXT_DOC + TECH_CONTEXT_DOC).
HAS_*= true → read file (unreadable → warning, continue)
6.5.3 Content Scope (Strict)
Extract from spec.md: domain glossary/terminology, cross-cutting constraints, reusable actors/systems/integrations/capabilities. Do NOT include: feature-specific flows/scenarios, objective-level details, feature-specific API/schema/infrastructure details.
6.5.4 Merge Strategy (Managed Section Full Rewrite)
Per target document:
- Maintain
## Project Context Baseline Updatessection - Parse + normalize existing entries
- Merge with new general-interest insights
- De-duplicate semantically
- Full rewrite of managed section; preserve all other content
- Section missing → create at end
6.5.5 Failure Handling
- Amendment failures are warnings, not blockers
- Continue workflow, include warnings in report
7. Report
Output:
- Branch name and spec file path
SPEC_TYPE,EPIC_ID(if present),spec_maturity: draft, validation results- Compliance check status (verify appended to file)
- Quick elicitation summary (questions asked/answered, or skipped if autopilot)
- Cross-feature overlap warnings (if any detected in Step 2.9)
- Shared document amendment summary (trigger status, updated files, warnings)
- Suggested next steps with context-specific prompts:
/sddp-clarify(optional — if NEEDS CLARIFICATION markers, ambiguous requirements, or overlap warnings suggest scope refinement)/sddp-plan(required)
