At a glance

Write an existing plan's code, phase by phase, until every acceptance criterion holds.

  • A plan exists and needs implementing
  • SKILL.md covers Actions, Transversal rules and References
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Code review

What it does

02 Implement is an agent skill from ai-driven-dev/framework. Write an existing plan's code, phase by phase, until every acceptance criterion holds. Use when a plan exists and needs implementing. Do NOT use to write a plan, review a diff.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `actions/01-prepare.md`, `actions/02-execute.md` and `actions/03-finalize.md`).

It sits in Agent Workflows, covering Code review and Planning. The repository describes itself as: Marketplace Framework AI-Driven Dev : Context Engineering, Plugins, Agents, Skills, Hooks, Templates, SDLC. The licence is MIT.

When your agent uses it

  • A plan exists and needs implementing
  • Tasks that involve Code review
  • Tasks that involve Planning

Example prompts

  • “/02-implement”

What it can do on your machine

Read from SKILL.md and the folder at commit 6e30640. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

02 Implement loads about 404 tokens when it runs, and up to ~511 if it reads all its reference files. Until then it costs about 47 tokens; SKILL.md has 179 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~404
With references · SKILL.md plus every file in references/, read only if the agent opens them
~511

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill: implement

Run an existing plan to write its code, one phase at a time, until every acceptance criterion holds.

Actions

#ActionRoleInput
01prepareResolve the plan, branch, mark it in-progressa plan path
02executeLoop the phases, code and assert eachprepared plan
03finalizeVerify and mark the plan implementedcoded phases

Run them in order, 01 → 03. Before running an action, read its file in actions/, not only the table or assets.

Transversal rules

  • Status: drive the plan through pending → in-progress → implemented (or blocked), and each phase through pending → in-progress → done. The in-progress values are runtime markers; only done and implemented need to land in a commit.
  • Commits: one commit per phase, its code together with the phase reaching done, plus a final commit for the plan reaching implemented. Never leave the tree dirty at a phase boundary. Do not scatter separate in-progress status commits: one context now owns both code and status, so there is nothing to guard against.
