# implement

This skill guides code changes and bug fixes while keeping test expectations intact. Use it when you need a clear account of checks that ran and checks that did not.

## What it does

\`implement` takes an accepted change from scope to verification. It asks the agent to note existing edits, make the smallest in-scope change, and check affected behavior. For a behavioral change, the workflow calls for a check that distinguishes the old behavior from the expected one.

The skill forbids weakening assertions, replacing checks with placeholders, or hiding failures to get a green result. It also requires checking consumers of edited interfaces and reporting exact commands and outcomes. A task that relies on a softened test is not treated as a valid repair.

The workflow uses the repository’s actual check recipe, runs targeted checks before broader integration, and inspects the diff against the original intent. Special cases such as authorized service operations or risky changes point to separate procedures. Only part of the workflow is available here.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill implement -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/implement/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/implement/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill implement -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/implement/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill implement -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/implement/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install boshu2/agentops implement
```

2. **Manually: put the files in place**
- File: `.github/skills/implement/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill implement -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/boshu2/agentops --path skills/implement
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/implement/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add boshu2/agentops --skill implement -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/boshu2/agentops/tree/HEAD/skills/implement/SKILL.md

## When to use it
- fix a defect without weakening tests
- keep a code change within accepted scope
- identify consumers affected by an interface change
- report checks that ran and those that did not

## Example prompts
- Fix this defect without weakening the tests, then report the checks you ran.
- Make the accepted change and give me the exact commands and results.
- Find which consumers this change affects and say how they are covered.

# Implement

Implement the accepted outcome. Repair ordinary known defects directly. Use the
existing intent; a clear edit needs no Plan first. Implement owns source changes
and factual checks. Read changed paths from Git (`git status --porcelain`,
`git diff --name-only <base>`), never from memory;
`ao provenance manifest --root <repo>` with one `--include <path>` per declared
path digests only the paths you declare and runs no Git. Copy check results from the command output.

## Rules that decide the result

- **Fix the cause, not the oracle.** Never loosen an assertion, tolerance,
  golden, fixture or suppression, or substitute a mock or placeholder, to turn
  a check green; nor change what the check runs against: code that acts
  differently under test or CI, a newly silenced failure path, or a check made
  non-blocking or skipped. A check that fails against accepted behavior points
  at a product defect; changing what the check accepts is an acceptance change
  and needs caller authority.
- **Find live consumers before editing.** Search the callers, readers, scripts,
  docs and tests of every edited function, type, path, format or message. For
  each one, state whether the change affects it and which check covers it. When
  retiring or renaming, consumers include installations, lookups and old-name
  invocations; preserve historical provenance. If the replaced interface never
  merged or shipped and every consumer update fits the scope, update them and
  delete the old version in the same change, with no alias or shim; otherwise
  keep the old version working or report it.
- **Name discriminating checks.** A behavioral change preserves RED
  for the expected missing behavior: name the check that fails before the edit
  and passes after ([Test's proof rule](../test/SKILL.md#critical-constraints)),
  plus the check for each affected consumer.
- **Report only what ran.** Give exact commands and results. List every check
  you did not or could not run as not run. Never call unrun work verified,
  fixed or green. Output can show as soon as a command runs, so keep secrets
