What it does

Implement is an agent skill from mag123c/toktrack. TDD implementation (RED→GREEN→REFACTOR) → verify → review

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/gates.md`).

It sits in Testing & QA, covering Test-driven development. It works with Rust. The repository describes itself as: Ultra-fast token & cost tracker for LLM Token Usage (e.g. Claude Code). The licence is MIT.

When your agent uses it

  • Tasks that involve Test-driven development

Example prompts

  • “/implement”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Analysis: Review plan, identify affected modules
  2. Gate pre-run (MUST — before coding)
  3. TDD Cycle
  4. Auto-call /verify: On implementation complete
  5. Auto-call /review: On verify pass
  6. Auto-call /wrap: On review PASS

What it can do on your machine

Read from SKILL.md and the folder at commit 75a86fa. 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

    Shell commands in SKILL.md call:

    • cargo
    • make

    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

Implement loads about 353 tokens when it runs, and up to ~660 if it reads all its reference files. Until then it costs about 17 tokens; SKILL.md has 133 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~353
With references · SKILL.md plus every file in references/, read only if the agent opens them
~660

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.

Implement

Flow

Analysis → Gate pre-run → TDD(RED→GREEN→REFACTOR) → /verify → /review → /wrap

Execution

  1. Analysis: Review plan, identify affected modules

  2. Gate pre-run (MUST — before coding) Run the PLAN's [unverified-gate: probe=…] / Phase 0 probes before RED. Fail → halt + report (don't build on a falsified assumption). Map Acceptance/DoD → RED tests; mark unverifiable as [unverified-gate] to carry to verify/wrap. Detail → references/gates.md (tag vocab: ../clarify/references/provenance.md).

    Rust-specific probes:

    • cargo check — whether it compiles
    • cargo test -- --list — verify test targets exist
    • make check — unified fmt + clippy + test gate

  3. TDD Cycle:

    • RED: Write failing test first
    • GREEN: Minimal code to pass
    • REFACTOR: Clean up (keep tests passing)

  4. Auto-call /verify: On implementation complete

  5. Auto-call /review: On verify pass

  6. Auto-call /wrap: On review PASS

Commands

bash
cargo test
cargo clippy -- -D warnings
cargo fmt --check

Rules

  • No implementation without test
  • On verify fail → fix and retry
  • On review FAIL → fix and retry
  • Complete full chain without stopping

When should I use Implement?

Implement fits situations like: tasks that involve Test-driven development.

How do I install Implement in Claude Code?

Run `npx skills add mag123c/toktrack --skill implement -a claude-code`. Or copy the skill folder (.claude/skills/implement in mag123c/toktrack) into .claude/skills/implement in your project. Claude Code loads it when a task matches its description.

How do I install Implement in Codex?

Run `npx skills add mag123c/toktrack --skill implement -a codex`. Or copy the skill folder (.claude/skills/implement in mag123c/toktrack) into .agents/skills/implement in your project. Codex loads it when a task matches its description.

Can I use Implement in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mag123c/toktrack --skill implement -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/implement, .gemini/skills/implement, .github/skills/implement and .opencode/skills/implement in your project.

What does Implement need to run?

Going by SKILL.md and its folder, Implement needs the command-line tools its instructions call (cargo and make).

Does Implement access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Implement safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Implement use?

Implement is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Implement use?

About 353 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 307 tokens, read only when the agent opens those files.

What are the alternatives to Implement?
