User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Pre-Execution Checks
Check for extension hooks (before analysis):
- Discover hooks across all extension files (multi-file discovery), not just the central file:
- Read
.specify/extensions.yml from the project root (if present) and collect entries under the hooks.before_analyze key.
- Then enumerate every
.specify/extensions/*/*.yml file in sorted order, parse each, and collect its hooks.before_analyze entries too — so a hook registered only in a per-extension file (e.g. the feedback extension at .specify/extensions/feedback/feedback.yml) is still discovered and runs.
- Merge all collected entries and dedupe by
(extension, command) (first occurrence wins, so a hook declared in both files runs once).
- If a file is absent, no hooks are registered, or its YAML cannot be parsed/is invalid, skip that file silently and continue.
- For every
optional: true hook that is discovered but not executed this phase, emit one line so the skip is a visible decision: Note: optional hook {extension}:{command} is registered but was not run (skipped).
- Filter out hooks where
enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
- Do not interpret or evaluate hook
condition expressions:
- If the hook has no
condition field, or it is null/empty, treat the hook as executable
- If the hook defines a non-empty
condition, skip the hook and leave condition evaluation to the HookExecutor implementation
- For each executable hook, output the following based on its
optional flag:
- Optional hook (
optional: true):
## Extension Hooks
**Optional Pre-Hook**: {extension}
Command: `/{command}`
Description: {description}
Prompt: {prompt}
To execute: `/{command}`
- Mandatory hook (
optional: false):
## Extension Hooks
**Automatic Pre-Hook**: {extension}
Executing: `/{command}`
EXECUTE_COMMAND: {command}
Wait for the result of the hook command before proceeding to the Goal.
Goal
Identify inconsistencies, duplications, ambiguities, and underspecified items across the three core artifacts (spec.md, plan.md, tasks.md) before implementation. This command MUST run only after /speckit-tasks has successfully produced a complete tasks.md.
Operating Constraints
STRICTLY READ-ONLY: Do not modify any files. Output a structured analysis report. Offer an optional remediation plan (user must explicitly approve before any follow-up editing commands would be invoked manually).
Constitution Authority: The project constitution (.specify/memory/constitution.md) is non-negotiable within this analysis scope. Constitution conflicts are automatically CRITICAL and require adjusting the spec, plan, or tasks — not diluting, reinterpreting, or silently ignoring the principle. Changing a principle itself must occur in a separate, explicit constitution update outside /speckit-analyze.
Execution Steps
1. Initialize Analysis Context
Run .specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks once from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS. Derive absolute paths:
- SPEC = FEATURE_DIR/spec.md
- PLAN = FEATURE_DIR/plan.md
- TASKS = FEATURE_DIR/tasks.md
Abort with an error message if any required file is missing (instruct the user to run missing prerequisite command).
For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'''m Groot' (or double-quote if possible: "I'm Groot").
2. Load Artifacts (Progressive Disclosure)
Load only the minimal necessary context from each artifact:
From spec.md:
- Overview/Context
- Functional Requirements
- Success Criteria (measurable outcomes — e.g., performance, security, availability, user success, business impact)
- User Stories
- Edge Cases (if present)
From plan.md:
- Architecture/stack choices
- Data Model references
- Phases
- Technical constraints
From tasks.md:
- Task IDs
- Descriptions
- Phase grouping
- Parallel markers [P]
- Referenced file paths
From constitution:
- Load
.specify/memory/constitution.md for principle validation
3. Build Semantic Models
Create internal representations (do not include raw artifacts in output):
- Requirements inventory: For each Functional Requirement (FR-###) and Success Criterion (SC-###), record a stable key — the explicit FR-/SC- identifier as primary key when present, optionally plus an imperative-phrase slug for readability (e.g., "User can upload file" →
user-can-upload-file). Include only Success Criteria requiring buildable work (e.g., load-testing infrastructure, security audit tooling); exclude post-launch outcome metrics and business KPIs (e.g., "Reduce support tickets by 50%").
- User story/action inventory: Discrete user actions with acceptance criteria
- Task coverage mapping: Map each task to one or more requirements or stories (inference by keyword / explicit reference patterns like IDs or key phrases)
- Constitution rule set: Extract principle names and MUST/SHOULD normative statements
4. Detection Passes (Token-Efficient Analysis)
Focus on high-signal findings. Limit to 50 findings total; aggregate remainder in overflow summary.
A. Duplication Detection
- Identify near-duplicate requirements
- Mark lower-quality phrasing for consolidation
B. Ambiguity Detection
- Flag vague adjectives (fast, scalable, secure, intuitive, robust) lacking measurable criteria
- Flag unresolved placeholders (TODO, TKTK, ???,
<placeholder>, etc.)
C. Underspecification
- Requirements with verbs but missing object or measurable outcome
- User stories missing acceptance criteria alignment
- Tasks referencing files or components not defined in spec/plan
D. Constitution Alignment
- Any requirement or plan element conflicting with a MUST principle
- Missing mandated sections or quality gates from constitution
E. Coverage Gaps
- Requirements with zero associated tasks
- Tasks with no mapped requirement/story
- Success Criteria requiring buildable work (performance, security, availability) not reflected in tasks
F. Inconsistency
- Terminology drift (same concept named differently across files)
- Data entities referenced in plan but absent in spec (or vice versa)
- Task ordering contradictions (e.g., integration tasks before foundational setup tasks without dependency note)
- Conflicting requirements (e.g., one requires Next.js while other specifies Vue)
G. Cross-Artifact Symbol Consistency (mechanical, FR-008)
Run the compiled, deterministic symbol set-difference as a real command — do
not eyeball it and do not hand-derive the set-difference:
./fake.sh build -t SymbolCrossCheck
Probe target availability first; skip-with-documented-notice when it is absent.
SymbolCrossCheck is a framework-repo-only governance target — generated projects
do not ship it, so the command fails there with Unknown … target: SymbolCrossCheck. Before invoking, probe whether the target resolves (e.g.
./fake.sh build --list / a target-resolution check), mirroring how the
evidence-graph step resolves the active feature from .specify/feature.json and
fails loudly only when nothing resolves. When SymbolCrossCheck resolves, run it and
fold its output in. When it is absent, do not fail the analysis: record a
documented skip notice in this report — Symbol consistency (analyze pass G): skipped — SymbolCrossCheck target not available in this project; manual cross-check is non-authoritative — and continue. The skip is a visible decision, not a silent
omission, and never blocks the invocation.
The target takes no file arguments: it resolves the active feature directory
(the DependencyReport pattern), reads plan.md, data-model.md, and tasks.md
from it, runs the SymbolCrossCheck analyzer in FS.Skia.UI.Build, prints the
markdown, and writes it to readiness/symbol-cross-check.md. Consume that output
and fold its findings into this report. The analyzer extracts named symbols by kind —
Msg cases, union/Screen variants, entity record names (backtick-quoted PascalCase
tokens on lines naming the kind), and FR-/SC- IDs — and reports each symbol whose
presence set is a proper subset of the three artifacts (present in some, missing
from others). It renders as:
## Symbol consistency (analyze pass G)
- msg-case ViewerKeyEventReceived — in {data-model, tasks}, missing from {plan}
- sc-id SC-009 — in {plan}, missing from {data-model, tasks}
Treatment: report set-differences as findings at the appropriate severity for
human judgment. A symbol present only in design (e.g. a start-state in
data-model.md with no matching spec FR) is flagged [design-only? human judgment] and is never hard-failed — design-ahead-of-spec is a legitimate
edge case (the cross-check is guidance, not a gate).
5. Severity Assignment
Use this heuristic to prioritize findings:
- CRITICAL: Violates constitution MUST, missing core spec artifact, or requirement with zero coverage that blocks baseline functionality
- HIGH: Duplicate or conflicting requirement, ambiguous security/performance attribute, untestable acceptance criterion
- MEDIUM: Terminology drift, missing non-functional task coverage, underspecified edge case
- LOW: Style/wording improvements, minor redundancy not affecting execution order
6. Produce Compact Analysis Report
Output a Markdown report (no file writes) with the following structure:
Specification Analysis Report
| ID | Category | Severity | Location(s) | Summary | Recommendation |
|---|
| A1 | Duplication | HIGH | spec.md:L120-134 | Two similar requirements ... | Merge phrasing; keep clearer version |
(Add one row per finding; generate stable IDs prefixed by category initial.)
Coverage Summary Table:
| Requirement Key | Has Task? | Task IDs | Notes |
|---|
Constitution Alignment Issues: (if any)
Unmapped Tasks: (if any)
Metrics:
- Total Requirements
- Total Tasks
- Coverage % (requirements with >=1 task)
- Ambiguity Count
- Duplication Count
- Critical Issues Count
7. Provide Next Actions
At end of report, output a concise Next Actions block:
- If CRITICAL issues exist: Recommend resolving before
/speckit-implement
- If only LOW/MEDIUM: User may proceed, but provide improvement suggestions
- Provide explicit command suggestions: e.g., "Run /speckit-specify with refinement", "Run /speckit-plan to adjust architecture", "Manually edit tasks.md to add coverage for 'performance-metrics'"
8. Offer Remediation
Ask the user: "Would you like me to suggest concrete remediation edits for the top N issues?" (Do NOT apply them automatically.)
9. Check for extension hooks
After reporting, discover hooks across all extension files (multi-file discovery), not just the central file:
Operating Principles
Context Efficiency
- Minimal high-signal tokens: Focus on actionable findings, not exhaustive documentation
- Progressive disclosure: Load artifacts incrementally; don't dump all content into analysis
- Token-efficient output: Limit findings table to 50 rows; summarize overflow
- Deterministic results: Rerunning without changes should produce consistent IDs and counts
Analysis Guidelines
- NEVER modify files (this is read-only analysis)
- NEVER hallucinate missing sections (if absent, report them accurately)
- Prioritize constitution violations (these are always CRITICAL)
- Use examples over exhaustive rules (cite specific instances, not generic patterns)
- Report zero issues gracefully (emit success report with coverage statistics)
