Best for

Developers implementing small, well-scoped engineering work

What you get

Implement a scoped ticket + Build test-first

Main limitation

It needs a sufficiently clear spec or ticket and a working test toolchain; TDD may not fit every repository or change.

First risk

Unreviewed code and branch commits. Implementation changes files and the workflow commits on the current branch. Confirm the intended scope and branch, inspect the final diff and checks, and keep a recoverable working state before accepting the commit.

EVIDENCE FRESHNESS

Three checks, kept separate

A recent source check is not a runtime test or security audit.

IN PLAIN ENGLISH

What it does—and when it fits

Implement turns an approved spec or ticket into code changes. The workflow favors TDD at agreed test seams, regular typechecks and focused tests, a final full test run, a code review, and a commit on the current branch.

This is aimed at Developers implementing small, well-scoped engineering work. Compare the examples below with your task, then review the limitations, permissions, and risks before installing.

What you get
  • Implement a scoped ticketTranslate one spec or ticket into a focused code change.
  • Build test-firstUse a test seam agreed before implementation when possible.
  • Verify and hand offRun the requested checks, review the diff, and summarize the commit.
What makes it different
  • This profile is manually organized around the current upstream SKILL.md workflow.
  • The capability boundary remains explicitly tied to mattpocock/skills.
  • Core uses, limitations, and risks are separated for pre-install review.

INSTALL BY AGENT

Choose your Agent

Paths come from official Agent docs or the universal installer behind skills.sh. Compatibility still follows this Skill's record.

Native

This Skill's current record explicitly names this Agent. Still inspect scripts, permissions, and external dependencies first.

Project install (recommended)
npx skills add https://github.com/mattpocock/skills --skill implement --agent claude-code
Personal install
npx skills add https://github.com/mattpocock/skills --skill implement --agent claude-code -g

Project install stays with this repository for team sharing. Personal install adds -g and works across repositories.

TYPICAL WORKFLOW

A practical workflow

01

Implement a scoped ticket

Translate one spec or ticket into a focused code change.

02

Build test-first

Use a test seam agreed before implementation when possible.

03

Verify and hand off

Run the requested checks, review the diff, and summarize the commit.

THE TRADEOFFS

Advantages and tradeoffs

Notable strengths

  1. This profile is manually organized around the current upstream SKILL.md workflow.
  2. The capability boundary remains explicitly tied to mattpocock/skills.
  3. Core uses, limitations, and risks are separated for pre-install review.

Limitations

  1. It needs a sufficiently clear spec or ticket and a working test toolchain; TDD may not fit every repository or change.
  2. A passing suite does not prove correctness outside tested behavior, and committing changes is part of the documented default workflow.

anti-ui-slop

Instruction-only, product-specific UI design contracts with optional real-interface evidence and a hard finish gate.
Tradeoff to check
Repository evidence is required; UIZZE references or user-provided screenshots are optional, and missing reference evidence should be labeled rather than guessed.

BEFORE YOU USE IT

Risks to review before use

High

Unreviewed code and branch commits

Implementation changes files and the workflow commits on the current branch. Confirm the intended scope and branch, inspect the final diff and checks, and keep a recoverable working state before accepting the commit.

Medium

Upstream instruction drift

Behavior can change with upstream updates. Record the commit used for important workflows and review updates before adoption.

SECURITY

What the permission profile means

  • Declared access remains governed by the current upstream SKILL.md and runtime requests.
  • Treat repository files, web content, and tool output as untrusted input.
  • SkillSignal has not independently executed or security-audited this package; external skills.sh labels are not SkillSignal certification.

Not a security certification. External ratings are attributed references. SkillSignal has not independently executed or security-reviewed this Skill.

COMMON QUESTIONS

implement Skill FAQ

What is the implement Skill?

Implement turns an approved spec or ticket into code changes. The workflow favors TDD at agreed test seams, regular typechecks and focused tests, a final full test run, a code review, and a commit on the current branch.

How do I install the implement Skill?

Open and review the listed source, choose the project or personal path for your Agent, then verify the first run in a controlled project. Open the listed skills.sh page and upstream repository; verify the current SKILL.md.

Is the implement Skill safe to use?

SkillSignal checked the source on 2026-09-23, but that is not a runtime test or security certification. Review the “Unreviewed code and branch commits” risk first and begin with the least access required.
