speckit-implement

speckit-implement is an agent for coding agents from boussadjra/vuestrata. It costs 21 tokens per session (114 once invoked), scanned A, original, MIT.

A task-execution tool for working through a feature task list one unfinished task at a time.

In plain words
What is it for?
Find the next task whose prerequisites are done, implement it, run its required quality checks, and report blockers.
Why use it?
It prevents dependent work from being started too early and requires each task to pass its checks before being marked complete.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

speckit-implement 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 5d ago.

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.

What it actually says

speckit-implement

Use when ready to implement the next task.

Instructions

  1. Read .specify/templates/commands/implement.md and the feature task list.
  2. Pick the first incomplete task whose dependencies are complete.
  3. Implement exactly one task.
  4. Run its required quality gates.
  5. Mark it complete only after verification.
  6. If blocked, report the blocker instead of skipping ahead.
Changes

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.
