What it does

Implement Change is an agent skill from pnpm/pnpm. Implement a pnpm feature, bug fix, or refactor by checking existing capabilities, prioritizing code reuse and deduplication, assessing architecture impact, and validating the final change. Use when asked to implement a change in this repository.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Data cleaning and Debugging. It works with pnpm. The repository describes itself as: Fast, disk space efficient package manager. The licence is MIT.

When your agent uses it

  • Asked to implement a change in this repository
  • Tasks that involve Data cleaning
  • Tasks that involve Debugging

Example prompts

  • “/implement-change”

What it can do on your machine

Read from SKILL.md and the folder at commit 3da5bd3. 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

Implement Change loads about 1.1k tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 556 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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 a pnpm feature, bug fix, or refactor by checking existing capabilities, prioritizing code reuse and deduplication, assessing architecture impact, and validating the final change. Use when asked to implement a change in this repository.

Implement a change

Apply PHILOSOPHY.md, AGENTS.md, and the relevant product instructions and style guides. Keep repository policy in those sources; this skill connects implementation to the testing-changes and review-code workflows.

Understand the problem before adding code

Establish the intended behavior and concrete success criteria from the user's request, reproduction, or specification. Determine which products and versions are affected using the repository's development policy. Reproduce bugs before choosing a fix when practical.

Always assess whether existing capabilities available to the affected product can solve the problem. For pnpm CLI work, consider combinations of commands, configuration, hooks, and workspace capabilities. For pnpr, assess its registry architecture, flags, and configuration. Consider applicable shared components across the repository as reuse candidates. Check their actual behavior against the success criteria. Prefer an existing capability when it fully solves the problem; explain how to use it and any limits. If it only partly solves the problem, identify the gap and extend the owning feature when that produces a cohesive design. Do not add a parallel feature merely because the request suggests a new setting or command. Respect an explicitly requested behavior that existing capabilities do not provide.

Assess the architecture

Before adding any new feature, analyze its effect on the overall architecture, not just the file being edited. Trace the affected data flow and responsibilities across commands, configuration, resolution, storage, or other relevant layers. Identify where the behavior belongs, which existing abstractions it extends, and how it interacts with related features and shared state or formats.

Summarize the architectural fit and meaningful tradeoffs before substantial implementation. Consider whether the change adds competing sources of truth, blurs a boundary, or introduces special cases other features will need to understand. Prefer a coherent extension over a local workaround. Keep necessary refactoring bounded to the change; architectural analysis is not authorization for an unrelated redesign.

Prioritize reuse and deduplication

Search for similar behavior, helpers, and tests before writing non-trivial logic. Inspect the relevant product and shared utilities, including callers of candidate helpers. Prioritize removing duplication over adding another copy.

If the needed logic already exists, reuse it. If it is not reusable yet, extract the common behavior into the appropriate shared helper or package and update the affected callers. When consolidating stable features would break compatibility, temporary duplication may remain until the next major version; identify the intended shared abstraction and consolidation point. Experimental features can be consolidated immediately. Apply the same check to similar logic introduced by the change. Preserve meaningful differences in contracts; do not force unrelated behavior into a generic abstraction merely because the code looks alike. Follow the repository's dependency placement and library reuse rules.

Implement and validate

Implement the smallest cohesive change that satisfies the intended behavior. Add tests that exercise its observable contract and relevant interactions, and update documentation and changesets when repository policy requires them.

Use testing-changes to select and run appropriate checks. Investigate failures. Then use review-code on the complete diff, fix verified findings, and rerun checks affected by the fixes. Reassess reuse and architectural fit against the final implementation.

Report what changed, existing capabilities considered, the reuse or extraction chosen, material architectural implications, and validation limits. Scale the explanation to the change. Commit, push, or open a PR only when the user or calling workflow authorizes it; use pull-requests when taking the change through a PR.

When should I use Implement Change?

Implement Change fits situations like: asked to implement a change in this repository; tasks that involve Data cleaning; tasks that involve Debugging.

How do I install Implement Change in Claude Code?

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

How do I install Implement Change in Codex?

Can I use Implement Change 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 pnpm/pnpm --skill implement-change -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-change, .gemini/skills/implement-change, .github/skills/implement-change and .opencode/skills/implement-change in your project.

What does Implement Change need to run?

SKILL.md names no scripts, command-line tools or credentials: Implement Change is instructions for the agent only.

Does Implement Change 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.
