speckit.tinyspec.implement

speckit.tinyspec.implement is a command for Codex from opsmill/infrahub-mcp. It costs 11 tokens per session (803 once invoked), scanned A, original, Apache-2.0.

An implementation command for completing a small change described in a TinySpec, a single-file feature document containing its requirements, plan, tasks, and completion criteria.

In plain words
What is it for?
Use it to implement a named TinySpec or the newest TinySpec, read its context files, carry out its plan, and mark finished tasks complete.
Why use it?
It keeps a small change’s instructions in one document and works through its task list directly. This avoids the heavier workflow intended for larger specifications.

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.tinyspec.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.

How it starts

The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TinySpec Implement

Implement a small change by following the plan and tasks in its tinyspec file. Works like /speckit.implement but optimized for single-file specs — reads one document, executes the tasks, and marks them complete.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty). The user may specify which tinyspec to implement (e.g., "logout-button") or a path to the tinyspec file.

Prerequisites

  1. Verify a spec-kit project exists by checking for .specify/ directory
  2. Verify git is available and the project is a git repository
  3. Locate the tinyspec file:
    • If user specifies a name, look for specs/tiny/{name}.md
    • If no input, look for the most recently created tinyspec in specs/tiny/
    • If no tinyspec files exist, suggest running /speckit.tinyspec first

Outline

  1. Read the tinyspec: Parse the tinyspec file to extract:

    • Context files: Files listed in the Context table
    • Requirements: The numbered requirements list
    • Plan: The ordered implementation steps
    • Tasks: The checkbox task list
    • Done When: The completion criteria
  2. Read context files: Load all files listed in the Context table to understand:

    • Current code structure and patterns
    • Existing imports and dependencies
    • Test patterns and conventions
  3. Execute tasks: Work through the task list in order:

    • For each task, follow the corresponding plan step
    • Implement the change in the identified file
    • Follow existing code patterns and conventions from context files
    • Mark each task as [x] in the tinyspec file after completion
  4. Run verification: After all tasks are complete:

    • Check that all "Done When" criteria are met
    • Verify tests pass (if test tasks were included)
    • Verify no lint errors (if linting is configured)
  5. Update tinyspec: Mark the tinyspec as complete:

    • Change **Status**: draft to **Status**: done
    • All task checkboxes should be [x]
    • All "Done When" checkboxes should be [x]

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.
