correctly parses and executes 99% of valid commands without errors +- **SC-006**: Help documentation is comprehensive enough that users can complete common tasks without external documentation (measured by reduction in support questions) +- **SC-007**: System handles 100+ concurrent agents without command processing degradation +- **SC-008**: Command history and logs enable root cause identification within 5 minutes for 90% of reported issues +- **SC-009**: Agent configuration changes take effect within 3 seconds and are confirmed to user +- **SC-010**: Task assignment and cancellation complete within 2 seconds and provide confirmation + +## Assumptions + +- **AS-001**: All commands are issued through the same Slack channel where agents are connected (single channel scope initially) +- **AS-002**: Agent configuration persists to local file on agent machine (e.g., .coorchat/config.json) and survives restarts +- **AS-003**: Task descriptions are free-form text and do not require structured format or GitHub issue integration initially +- **AS-004**: Task queues have configurable depth limit per agent (default 50 items), adjustable based on machine capabilities +- **AS-005**: All users in the Slack channel are authorized to issue commands (trust-based, no role-based access control initially) +- **AS-006**: Agents implement command handlers for configuration changes (model switching, role changes) - this requires agent-side implementation +- **AS-007**: The relay server (ConnectionManager) provides API to query connected agents and their metadata +- **AS-008**: Response formatting prioritizes readability over compactness (may use multiple messages for long responses) +- **AS-009**: Command history is retained in-memory for current session only (no long-term persistence) +- **AS-010**: Natural language parsing is limited to structured commands initially; full NLP (e.g., "what's T14 doing?") is future enhancement + +## Dependencies + +- **DEP-001**: Existing SlackChannel implementation for receiving text messages and sending responses +- **DEP-002**: Relay server ConnectionManager API for querying connected agents +- **DEP-003**: Agent-side command handlers for processing configuration requests (model, role, pause/resume, queue limits) +- **DEP-004**: Existing MessageType protocol for task assignment and coordination +- **DEP-005**: Agent-side logging capability for "logs" command to retrieve log entries +- **DEP-006**: Agent-side local file storage for persisting configuration (e.g., .coorchat/config.json on agent machine) + +## Out of Scope + +- **OOS-001**: Advanced natural language processing (accepting "show me all agents" vs. only "list agents") +- **OOS-002**: Role-based access control (admin vs. viewer permissions) +- **OOS-003**: Centralized database for configuration (local file storage is sufficient) +- **OOS-004**: GitHub issue integration for task management +- **OOS-005**: Web-based UI or alternative interfaces (Slack only) +- **OOS-006**: Multi-channel coordination (agents in different Slack channels) +- **OOS-007**: Scheduled commands or automation (cron-like functionality) +- **OOS-008**: Agent-to-agent communication initiated by commands +- **OOS-009**: Command macros or aliases (user-defined shortcuts) +- **OOS-010**: Audit trail export or compliance reporting features
