Salacia Init

Generate a scope contract for the current task.

What to do

1. Ask the user what task they're working on (or read from git branch name / recent context)

2. Analyze the task description to extract:

   • Keywords → map to file paths (use project structure)
   • Quoted file paths in the description
   • Conventional commit prefix (feat/fix/docs/chore) → scope width

3. Check .salacia/memory.json for historical patterns. If it exists, read the pattern matching the detected task type (feat/fix/etc.). Pre-fill softAllowedPaths with entries where weight >= 0.5. This lets the contract benefit from past session learning.

4. Generate .salacia/contract.json:

{
  "taskId": "<from branch or user input>",
  "allowedPaths": ["<extracted paths>"],
  "softAllowedPaths": ["<sibling dirs, co-change companions>"],
  "excludedPaths": ["node_modules/**", ".git/**", "dist/**"],
  "protectedPaths": [".env", ".env.*", "*.pem", "*.key", "*.cert", "package-lock.json", "bun.lockb"],
  "maxFilesChanged": 10,
  "generatedAt": "<timestamp>",
  "generatedBy": "heuristic"
}

5. Also create .salacia/config.json if it doesn't exist:

{
  "enabled": true,
  "driftThreshold": 30
}

6. Reset .salacia/drift.json to zero state:

{
  "score": 0,
  "files": [],
  "softFiles": [],
  "outOfScope": [],
  "protected": []
}

7. Report the contract summary to the user (include any memory-derived soft paths)

Scope width heuristics

• fix: narrow — only files mentioned + their test files
• feat: medium — mentioned files + sibling directory + tests
• refactor: wide — entire package the files belong to
• docs: docs/** + README.md only
• chore: wide — config files + root files allowed

Notes

• Contract is stored in .salacia/ (gitignored)
• The guard hook (PreToolUse/PostToolUse) reads this contract automatically
• Zero token cost for enforcement — hooks run as shell commands
• To disable: set enabled: false in .salacia/config.json
