# Mosaic Universal Agent Standards

This file is the canonical standards contract for agent sessions on this machine.

Master/slave model:
- Master: `~/.mosaic` (this framework)
- Slave: each repo bootstrapped via `mosaic-bootstrap-repo`

## Execution Model

1. Load this file first.
2. Load project-local `AGENTS.md` next.
3. Respect repository-specific tooling and workflows.
4. Use lifecycle scripts when available (`scripts/agent/*.sh`).
5. Use shared rails/guides from `~/.mosaic` as canonical references.

## Non-Negotiables

- Data files are authoritative; generated views are derived artifacts.
- Pull before edits when collaborating in shared repos.
- Run validation checks before claiming completion.
- Apply quality rails from `~/.mosaic/rails/` when relevant (review, QA, git workflow).
- For project-level mechanical enforcement templates, use `~/.mosaic/rails/quality/` via `~/.mosaic/bin/mosaic-quality-apply`.
- For runtime-agnostic delegation/orchestration, use `~/.mosaic/rails/orchestrator-matrix/` with repo-local `.mosaic/orchestrator/` state.
- Avoid hardcoded secrets and token leakage in remotes/commits.
- Do not perform destructive git/file actions without explicit instruction.

## Session Lifecycle Contract

- Start: `scripts/agent/session-start.sh`
- Priority scan: `scripts/agent/critical.sh`
- End: `scripts/agent/session-end.sh`
- Limitation logging helper: `scripts/agent/log-limitation.sh "Title"`

If a repo does not expose these scripts, run equivalent local workflow commands and document deviations.

## Multi-Agent Safety

- Coordinate through git pull/rebase discipline.
- Do not auto-resolve data conflicts in shared state files.
- Keep commits scoped to a single logical change set.

## Prompting Contract

All runtime adapters should inject:

- `~/.mosaic/STANDARDS.md`
- project `AGENTS.md`

before task execution.

Runtime-compatible guides and rails are hosted at:

- `~/.mosaic/guides/`
- `~/.mosaic/rails/`
- `~/.mosaic/profiles/` (runtime-neutral domain/workflow/stack presets)
- `~/.mosaic/runtime/` (runtime-specific overlays)
- `~/.mosaic/skills-local/` (local private skills shared across runtimes)
