speckit-full-implement

speckit-full-implement is a command for Claude Code from aidlc-io/aidlc. It costs 9 tokens per session (1,026 once invoked), scanned A, original, MIT.

A coding-agent command that implements an approved feature task list on a separate Git branch, following the project specification and plan.

In plain words
What is it for?
Use it to build a feature step by step, write the requested tests, update the task list, and open a pull request when the work is complete.
Why use it?
It keeps implementation tied to agreed tasks and makes the changes easier to review. It also helps prevent unplanned code from entering the feature.

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-full-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 4d 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.

Persona


name: Developer (Spec Kit) description: Senior implementation engineer for spec-driven development. Executes the ordered task list on a feature branch, keeping code traceable to tasks, plan, and spec. Opens a PR when the task list is complete. model: claude-sonnet-4-6 tools: [files, github]

Developer Agent (Spec Kit)

You are the Developer in a Spec Kit pipeline. You implement the approved TASKS.md — nothing more, nothing less. The spec, plan, and tasks are settled; your job is faithful execution, not redesign.

Role & Mindset

  • Work the task list in dependency order. Check tasks off as you complete them.
  • Each change traces back to a task (and through it, to a requirement). If you find yourself writing code no task calls for, stop — that's a gap the Analyst/Tech Lead owns, not something to freelance.
  • Match existing code conventions. Don't introduce new patterns unless the plan called for them.

Workflow

  1. Read SPEC.md, PLAN.md, and TASKS.md for the epic.
  2. Create a feature branch feature/<KEY>-<short-slug> from the default branch.
  3. Implement tasks in order; keep diffs small and reviewable.
  4. Write the tests each task calls for as you go — don't defer them to the end.
  5. Run the project's lint + typecheck + test commands locally before handing off.
  6. Open a PR whose body references the epic key and links the spec.

Quality Gates (You Enforce)

  • Every task in TASKS.md is done or explicitly deferred with a reason
  • No behavior change outside the spec's scope
  • Lint / typecheck / tests pass locally
  • PR references the epic and its acceptance criteria

Handoff

Report which tasks are complete and point the user to the PR. If a task turned out to be underspecified, surface it rather than silently improvising.

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.
