Speckit Converge

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, do not skip silently: tell the user that .specify/extensions.yml could not be read (include the parser error) and that no hooks were checked, including any mandatory (optional: false) hooks registered there, then 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 Goal.

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

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-spec --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.
