User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Pre-Execution Checks
Check for extension hooks (before clarification):
- Check if
.specify/extensions.yml exists in the project root.
- If it exists, read it and look for entries under the
hooks.before_clarify key
- If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
- Filter out hooks where
enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
- For each remaining hook, do not attempt to 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
- When constructing command invocations from hook command names, replace dots (
.) with hyphens (-). For example, speckit.git.commit → /speckit-git-commit.
- 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 Outline.
After emitting the block above you MUST actually invoke the hook and wait for it to finish before continuing. Run it the same way you would run the command yourself in this agent/session (the invocation may differ from the literal {command} id shown above, e.g. a skills-mode agent runs it as /skill:speckit-... or $speckit-...). Emitting the block alone does not run the hook.
- If no hooks are registered or
.specify/extensions.yml does not exist, skip silently
Outline
Goal: Detect and reduce ambiguity or missing decision points in the active feature specification and record the clarifications directly in the spec file.
Note: This clarification workflow is expected to run (and be completed) BEFORE invoking /speckit-plan. If the user explicitly states they are skipping clarification (e.g., exploratory spike), you may proceed, but must warn that downstream rework risk increases.
Execution steps:
-
Run .specify/scripts/bash/check-prerequisites.sh --json --paths-only from repo root once (combined --json --paths-only mode / -Json -PathsOnly). Parse minimal JSON payload fields:
FEATURE_DIR
FEATURE_SPEC
- (Optionally capture
IMPL_PLAN, TASKS for future chained flows.)
- If JSON parsing fails, abort and instruct user to re-run
/speckit-specify or verify feature branch environment.
- 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").
-
IF EXISTS: Load .specify/memory/constitution.md for project principles and governance constraints.
-
Load the current spec file. Perform a structured ambiguity & coverage scan using this taxonomy. For each category, mark status: Clear / Partial / Missing. Produce an internal coverage map used for prioritization (do not output raw map unless no questions will be asked).
Functional Scope & Behavior:
- Core user goals & success criteria
- Explicit out-of-scope declarations
- User roles / personas differentiation
Domain & Data Model:
- Entities, attributes, relationships
- Identity & uniqueness rules
- Lifecycle/state transitions
- Data volume / scale assumptions
Interaction & UX Flow:
- Critical user journeys / sequences
- Error/empty/loading states
- Accessibility or localization notes
Non-Functional Quality Attributes:
- Performance (latency, throughput targets)
- Scalability (horizontal/vertical, limits)
- Reliability & availability (uptime, recovery expectations)
- Observability (logging, metrics, tracing signals)
- Security & privacy (authN/Z, data protection, threat assumptions)
- Compliance / regulatory constraints (if any)
Integration & External Dependencies:
- External services/APIs and failure modes
- Data import/export formats
- Protocol/versioning assumptions
Edge Cases & Failure Handling:
- Negative scenarios
- Rate limiting / throttling
- Conflict resolution (e.g., concurrent edits)
Behavior rules:
- If no meaningful ambiguities found (or all potential questions would be low-impact), respond: "No critical ambiguities detected worth formal clarification." and suggest proceeding.
- If spec file missing, instruct user to run
/speckit-specify first (do not create a new spec here).
- Never exceed 5 total asked questions (clarification retries for a single question do not count as new questions).
- Avoid speculative tech stack questions unless the absence blocks functional clarity.
- Respect user early termination signals ("stop", "done", "proceed").
- If no questions asked due to full coverage, output a compact coverage summary (all categories Clear) then suggest advancing.
- If quota reached with unresolved high-impact categories remaining, explicitly flag them under Deferred with rationale.
Context for prioritization: $ARGUMENTS
Mandatory Post-Execution Hooks
You MUST complete this section before reporting completion to the user.
Check if .specify/extensions.yml exists in the project root.
- If it does not exist, or no hooks are registered under
hooks.after_clarify, skip to the Completion Report.
- If it exists, read it and look for entries under the
hooks.after_clarify key.
- If the YAML cannot be parsed or is invalid, skip hook checking silently and continue to the Completion Report.
- Filter out hooks where
enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
- For each remaining hook, do not attempt to 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
- When constructing command invocations from hook command names, replace dots (
.) with hyphens (-). For example, speckit.git.commit → /speckit-git-commit.
- For each executable hook, output the following based on its
optional flag:
- Mandatory hook (
optional: false) — You MUST emit EXECUTE_COMMAND: for each mandatory hook:
## Extension Hooks
**Automatic Hook**: {extension}
Executing: `/{command}`
EXECUTE_COMMAND: {command}
After emitting the block above you MUST actually invoke the hook and wait for it to finish before continuing. Run it the same way you would run the command yourself in this agent/session (the invocation may differ from the literal {command} id shown above, e.g. a skills-mode agent runs it as /skill:speckit-... or $speckit-...). Emitting the block alone does not run the hook.
- Optional hook (
optional: true):
## Extension Hooks
**Optional Hook**: {extension}
Command: `/{command}`
Description: {description}
Prompt: {prompt}
To execute: `/{command}`
Completion Report
Report completion (after questioning loop ends or early termination):
- Number of questions asked & answered.
- Path to updated spec.
- Sections touched (list names).
- Spec quality checklist status (if
FEATURE_DIR/checklists/requirements.md was re-validated): show before/after pass counts (e.g., "Spec Quality Checklist: 12/16 → 15/16 items passing") and list any items that changed state — both newly checked (unchecked → checked) and any regressions (checked → unchecked). If any items remain unchecked, list them as areas needing attention.
- Coverage summary table listing each taxonomy category with Status: Resolved (was Partial/Missing and addressed), Deferred (exceeds question quota or better suited for planning), Clear (already sufficient), Outstanding (still Partial/Missing but low impact).
- If any Outstanding or Deferred remain, recommend whether to proceed to
/speckit-plan or run /speckit-clarify again later post-plan.
- Suggested next command.
