# Agent Instructions

Use documentation selectively.

Always read the minimum relevant documentation before making changes.

## Required documentation by task type

### Small scoped changes
For small UI fixes, copy updates, styling adjustments, or isolated bug fixes:
- read only the directly relevant files
- do not read project-wide documentation unless needed

### Feature-scoped changes
For changes affecting an existing feature:
- read the matching file in `specs/`
- read `docs/ARCHITECTURE.md` only if the change affects structure or flow

### Large or cross-cutting changes
For new features, architecture changes, domain rule changes, or public behavior changes:
- read:
  - docs/ARCHITECTURE.md
  - docs/DOMAIN_RULES.md
  - docs/FEATURES.md
- also read the matching file in `specs/` when applicable

## Core rules

- Do not introduce new patterns, abstractions, or frameworks unless explicitly requested.
- Do not refactor unrelated code.
- Do not rename files, folders, database fields, or public interfaces unless explicitly requested.
- Follow the existing folder structure and module boundaries.
- Keep changes minimal, scoped, and consistent with the current codebase.
- Reuse existing primitives, services, validators, helpers, and utilities whenever possible.
- Preserve the current implementation unless the task explicitly requires changing it.

## Documentation updates

Update documentation only when implementation changes affect:
- feature scope
- business rules
- architectureڑڑ
- public behavior

Do not update documentation for small isolated fixes or purely visual changes.

Update only the relevant files in:
- docs/
- specs/

Keep documentation aligned with the real implementation, not assumptions.

## Git Commit Messages

Use this format:
```text
TYPE - Short summary

- First concrete change
- Second concrete change
- Third concrete change
```
Allowed types:
`ADDED, IMPROVED, FIXED, CHANGED, REFACTORED, OPTIMIZED, REMOVED, UPDATED,
SECURED, TESTED, DOCUMENTED, STYLED, CONFIGURED, RENAMED, MOVED, CLEANED,
REVERTED`

Rules:
- Write commit messages in English.
- Use uppercase type names.
- Keep the title concise.
- Add a blank line before the bullet list.
- Describe only the actual changes in the commit.
- Inspect `git diff --cached` before writing the message.
- Do not add AI attribution or Co-Authored-By.
- Do not create commits unless explicitly requested (see Core Rules above).

## graphify (when present)

- For codebase questions, if `graphify-out/graph.json` exists, run
  `graphify query "<question>"` first. Use `graphify path "<A>" "<B>"` for
  relationships and `graphify explain "<concept>"` for focused concepts —
  these return a scoped subgraph, usually much smaller than
  `GRAPH_REPORT.md` or raw grep output.
- If `graphify-out/wiki/index.md` exists, use it for broad navigation
  instead of raw source browsing.
- Read `graphify-out/GRAPH_REPORT.md` only for broad architecture review or
  when query/path/explain don't surface enough context.
- After modifying code, run `graphify update .` to keep the graph current
  (AST-only, no API cost).
