converge

A completion-checking command that compares the codebase with the feature specification, plan, and task list, then adds missing work to tasks.md.

In plain words
What is it for?
Use it after implementation to find gaps between the code and the project’s design artifacts and record remaining tasks.
Why use it?
It exposes work that was planned but not built, so the implementation process can continue toward the documented feature.

Getting it into your agent

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

converge scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
      

      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_COMMAND_IMPLEMENT__ can complete it. This command MUST run only after __SPECKIT_COMMAND_IMPLEMENT__ has run on the current tasks.md, and after __SPECKIT_COMMAND_TASKS__ has produced a complete tasks.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

converge is a command published in the GitHub repository github/spec-kit (132,298 stars, last pushed 3d ago), licensed MIT. It adds 35 tokens to every session and 2,943 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
