User Input#

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Pre-Execution Checks#

Check for extension hooks (before convergence):

• Check if .specify/extensions.yml exists in the project root.

• If it exists, read it and look for entries under the hooks.before_converge 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

• 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.
    

• If no hooks are registered or .specify/extensions.yml does not exist, skip silently

Goal#

Close the gap between what a feature's specification, plan, and tasks call for and what the
codebase currently implements. Read spec.md, plan.md, and tasks.md as the sole
source of intent (with the constitution as governing constraints), assess the current
state of the code, determine which requirements, acceptance criteria, plan decisions, and
existing tasks are unmet, incomplete, or only partially satisfied, and append each piece
of remaining work as a new, traceable task at the bottom of tasks.md so that
/speckit.implement can complete it. This command MUST run only after
/speckit.implement has run on the current tasks.md, and after /speckit.tasks has produced a complete tasks.md.

This is not a diff tool and does not track changes. It assesses the present state
of the code relative to the feature's artifacts — no git, no branch comparison, no history.

Operating Constraints#

APPEND-ONLY, NEVER REWRITE: The command's only write is appending a new
## Phase N: Convergence section to tasks.md. It MUST NOT:

• modify spec.md or plan.md in any way;
• rewrite, renumber, reorder, or delete any existing task (including tasks from a prior
  Convergence phase);
• modify, create, or delete any application code — completing the appended tasks is the
  job of /speckit.implement.

When the codebase already satisfies everything, the command MUST leave tasks.md
byte-for-byte unchanged (no empty Convergence header) and report a clean result.

Constitution Authority: The project constitution (.specify/memory/constitution.md) is
non-negotiable. Code that violates a MUST principle is the highest-severity finding and
produces a corresponding remediation task. If the constitution is an unfilled template,
skip constitution checks gracefully rather than failing.

Execution Steps#

1. Initialize Convergence 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
• CONSTITUTION = .specify/memory/constitution.md (if present)
  If spec.md, plan.md, or tasks.md is missing, STOP with a clear, actionable message naming the
  prerequisite command to run (/speckit.specify for a missing spec, /speckit.plan for a missing plan,
  /speckit.tasks for missing tasks). Do not produce partial output.
  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:

• Functional Requirements (FR-###)
• Success Criteria (SC-###) — include only items requiring buildable work; exclude
  post-launch outcome metrics and business KPIs
• User Stories and their Acceptance Scenarios
• Edge Cases (if present)

From plan.md:

• Architecture/stack choices and technical decisions
• Data Model references
• Phases and named touch-points (files/components the plan says will be created or edited)
• Technical constraints

From tasks.md:

• Task IDs (to compute the next ID and next phase number)
• Descriptions, phase grouping, and referenced file paths

From constitution (if not an unfilled template):

• Principle names and MUST/SHOULD normative statements

3. Build the Intent Inventory#

Create an internal model (do not echo raw artifacts):

• Requirements inventory: one stable key per FR-### / SC-### / user-story acceptance
  scenario (e.g. US1/AC2), plus the plan decisions and constitution principles that
  impose buildable obligations.
• Code-scope map: from the file paths named in plan.md and tasks.md, plus a keyword
  search for the concepts each requirement describes, derive the set of source files and
  components in scope for assessment. Bound the assessment to these — do not infer
  scope beyond what the artifacts define.

4. Assess the Codebase and Classify Findings#

For each item in the intent inventory, inspect the current code in scope and produce a
Finding only where there is a gap. Classify every finding by gap type:

• missing: the required work is absent from the code entirely.
• partial: the work exists but does not yet fully satisfy the requirement /
  acceptance criterion / plan decision.
• contradicts: the code does something that conflicts with stated intent or a
  constitution MUST principle.
• unrequested: the code contains work not called for by the spec, plan, or tasks
  (surfaced for awareness — converge does not delete code, it only appends a task to
  review/justify or remove it).

Each Finding records: a stable id, the source-ref it traces to, the gap-type, a
severity, and a short human-readable description with the evidence (the file/area observed).

Edge cases:

• Little or no code yet: treat the entire specified scope as missing remaining work
  rather than failing.
• Nothing remains: produce zero findings and follow the converged branch in Step 7.

5. Assign Severity#

• CRITICAL: violates a constitution MUST principle, or a missing/contradicts gap
  that blocks baseline functionality of a P1 user story.
• HIGH: a missing or partial gap on a core functional requirement or acceptance
  criterion.
• MEDIUM: a partial gap on a secondary requirement, or an unrequested addition with
  unclear justification.
• LOW: minor partial gaps, polish, or low-risk unrequested additions.

6. Present the In-Session Findings Summary#

Before appending anything, output a compact, severity-graded summary (no file writes yet):

Convergence Findings#

Summary metrics:

• Requirements / acceptance criteria checked
• Plan decisions checked
• Constitution principles checked (or "skipped — template")
• Findings by gap type (missing / partial / contradicts / unrequested)
• Findings by severity

7. Append Convergence Tasks (or report converged)#

If there are one or more actionable findings (tasks_appended outcome):

Append to the end of tasks.md, per the append contract:

1. Scan all existing task IDs; let M be the maximum. Determine the next phase number N
   (highest existing phase + 1).

2. Write a single new section header ## Phase N: Convergence.

3. Emit one checklist item per actionable finding, ordered CRITICAL/HIGH first, assigning
   zero-padded IDs T{M+1:03d}, T{M+2:03d}, …:

   ⧉

   - [ ] T042 <imperative description> per <source-ref> (<gap-type>)
   

   <source-ref> traces the task to its origin: e.g. FR-003, SC-002,
   US1/AC2, plan: storage decision, Constitution II.

   <gap-type> is one of missing, partial, contradicts, unrequested.

   Constitution-violation tasks MUST be emitted first and described as
   CRITICAL.

4. Never reuse or renumber existing IDs. If a prior Convergence phase exists, add a new,
   separately-numbered one below it — do not touch the old one.

If there are no actionable findings (converged outcome):

• Do not modify tasks.md at all — no empty phase header.
• Report: "✅ Converged — the implementation satisfies the spec, plan, and tasks."
• Include the summary counts of what was checked.

8. Provide Next Actions (Handoff)#

• On tasks_appended: state how many tasks were appended under which phase, and recommend
  running /speckit.implement to complete them; note that a follow-up converge
  run will find fewer or no remaining items.
• On converged: recommend proceeding to review / opening a PR. No further implement pass
  is needed for this feature's specified scope.

9. Check for extension hooks#

After producing the result, check if .specify/extensions.yml exists in the project root.

• If it exists, read it and look for entries under the hooks.after_converge 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

• Report the convergence outcome (converged or tasks_appended) in-session before listing
  any hooks, so users can decide whether to run optional follow-up commands.

• For each executable hook, output the following based on its optional flag:

  • Optional hook (optional: true):

    ⧉

    ## Extension Hooks
    
    **Optional Hook**: {extension}
    Command: `/{command}`
    Description: {description}
    
    Prompt: {prompt}
    To execute: `/{command}`
    

  • Mandatory hook (optional: false):

    ⧉

    ## Extension Hooks
    
    **Automatic Hook**: {extension}
    Executing: `/{command}`
    EXECUTE_COMMAND: {command}
    

• If no hooks are registered or .specify/extensions.yml does not exist, skip silently
