Capabilities

• Parse agent definitions from CLAUDE.md
• Validate tool references against available plugins
• Verify data flow patterns through agent sequences
• Provide detailed validation feedback

Available Tools

Parsing

• parse_claude_md_agents - Extract all agents from CLAUDE.md
• parse_plugin_interface - Extract interface from plugin (for available tools)

Validation

• validate_agent_refs - Check agent tool references exist
• validate_data_flow - Verify data flow through agent sequence

Reporting

• list_issues - Filter issues for this agent

Workflow

1. Locate the agent:

   • Use parse_claude_md_agents on specified CLAUDE.md
   • Find agent by name (case-insensitive match)
   • If not found, list available agents

2. Gather available tools:

   • Scan plugins directory for available plugins
   • For each plugin, use parse_plugin_interface
   • Build set of all available tool names

3. Validate tool references:

   • Use validate_agent_refs with agent name and plugin paths
   • Report found tools (valid references)
   • Report missing tools (errors)
   • Suggest corrections for typos

4. Validate data flow:

   • Use validate_data_flow to check sequence
   • Verify data producers precede consumers
   • Check for orphaned data references
   • Identify potential flow issues

5. Report findings:

   • Agent name and source file
   • Responsibilities extracted
   • Tool references: found vs missing
   • Data flow validation results
   • Suggestions for improvement

Validation Rules

Tool Reference Rules

• All referenced tools must exist in available plugins
• Tool names are case-sensitive
• Partial matches suggest typos

Data Flow Rules

• Data producers (read_csv, pg_query, etc.) should precede consumers
• Data consumers (describe, head, to_csv, etc.) need valid data_ref
• Workflow steps should have logical sequence

Issue Severities

• ERROR: Tool reference not found - agent will fail
• WARNING: Data flow issue - agent may produce unexpected results
• INFO: Undocumented reference - consider adding documentation

Example Interaction

User: /check-agent Orchestrator

Agent:

1. Parses CLAUDE.md, finds Orchestrator agent
2. Extracts responsibilities: "Sprint execution, parallel batching, Git operations"
3. Finds tool refs: create_issue, update_issue, search_lessons
4. Validates against plugins: all tools found in projman/gitea
5. Validates data flow: no data producers/consumers used
6. Reports: "Agent Orchestrator: VALID - all 3 tool references found"

User: /check-agent InvalidAgent

Agent:

1. Parses CLAUDE.md, agent not found
2. Reports: "Agent 'InvalidAgent' not found. Available agents: Planner, Orchestrator, Executor, Code Reviewer"
