/repo-map - AST Repo Map

Generate a cached repository map of symbols and imports using ast-grep. This enables faster drift detection and more accurate code context.

Arguments

Parse from $ARGUMENTS:

•Action: init | update | status | rebuild (default: status)
•--force: Force rebuild (for init)
•--full: Force full rebuild (for update)

Examples:

•/repo-map init
•/repo-map update --full
•/repo-map status

Execution

1) Load Repo Map Module

javascript

const { getPluginRoot } = require('@agentsys/lib/cross-platform');
const pluginRoot = getPluginRoot('repo-map');
if (!pluginRoot) { console.error('Error: Could not locate repo-map plugin root'); process.exit(1); }
const repoMap = require(`${pluginRoot}/lib/repo-map`);

2) Parse Arguments

javascript

const args = '$ARGUMENTS'.split(' ').filter(Boolean);
const action = (args[0] || 'status').toLowerCase();

const options = {
  force: args.includes('--force'),
  full: args.includes('--full')
};

3) Ensure ast-grep is Available

javascript

const installed = await repoMap.checkAstGrepInstalled();
if (!installed.found || !repoMap.installer.meetsMinimumVersion(installed.version)) {
  const suggestion = repoMap.getInstallInstructions();
  const choice = await request_user_input({
    questions: [{
      header: 'Install ast-grep?',
      question: 'ast-grep is required for repo-map. Install now?',
      options: [
        { label: 'Install via npm', description: 'Runs: npm install -g @ast-grep/cli' },
        { label: 'Skip for now', description: 'Show install instructions and exit' }
      ]
    }]
  });

  if (choice?.[0] === 'Install via npm') {
    await Bash('npm install -g @ast-grep/cli');
  } else {
    console.log(suggestion);
    return;
  }
}

4) Run Action

javascript

let result;

if (action === 'init' || action === 'rebuild') {
  result = await repoMap.init(process.cwd(), {
    force: action === 'rebuild' || options.force
  });
} else if (action === 'update') {
  result = await repoMap.update(process.cwd(), { full: options.full });
} else if (action === 'status') {
  result = repoMap.status(process.cwd());
} else {
  console.log('Unknown action. Use: init | update | status | rebuild');
  return;
}

if (result?.success === false) {
  console.log(result.error || 'Repo-map failed');
  if (result.installSuggestion) console.log(result.installSuggestion);
  return;
}

if (action === 'status' && !result.exists) {
  console.log('No repo-map found. Run /repo-map init to generate one.');
  return;
}

5) Validate Results (init/update only)

After init or update, run validation using the lightweight agent:

javascript

if (action === 'init' || action === 'rebuild' || action === 'update') {
  const summary = result?.map?.stats || result?.summary || result?.changes || {};
  const validation = await Task({
    subagent_type: 'repo-map:map-validator',
    prompt: `Validate repo-map results. Summary: ${JSON.stringify(summary)}`
  });
  console.log(validation);
}

Output Format

markdown

## Repo Map Result

**Action**: init|update|status
**Files**: <count>
**Symbols**: <count>
**Languages**: <list>
**Commit**: <hash>
