HeadMaster defines 12 tools with basic schemas and descriptions, but falls significantly short of production quality. Tool names lack consistent verb-noun structure (archive_feature, list_archived_features, restore_feature are acceptable; jira_* tools are generic). Descriptions are present but minimal (avg ~60 chars, well below the 194-char baseline). Parameter descriptions exist but are sparse and lack constraint details (e.g., no enum for jira_transition_issue's 'transition_name', no format guidance for 'jql'). No output schemas are documented anywhere in the source. Error handling is absent, no recovery guidance, no categorization of retryable vs fatal errors. Security concerns: no evidence of secret injection for Jira credentials (likely passed via env vars, but not validated in code). Tool composition is reasonable (single responsibility per tool), but parameter relationships are undocumented (e.g., jira_update_issue has optional fields with no guidance on which combinations are valid).

• Document output schemas for all tools. For jira_search_issues, specify: returns array of {issue_key, summary, status, assignee, created, updated}. For jira_read_issue, specify all returned fields and their types.
• Add enum constraints to categorical parameters. jira_transition_issue's 'transition_name' should accept only valid transitions for the issue's current status (e.g., 'Start Progress', 'Done', 'In Review'). Provide a discovery tool (jira_get_transitions) if transitions are dynamic.
• Expand parameter descriptions with constraints and examples. E.g., 'max_results: integer, 1 - 100 (default 50). Limits API load and context window usage.' 'force: boolean. If true, archive even if feature is incomplete, use with caution.'
• Add error handling guidance. E.g., jira_read_issue: 'If issue not found, returns error with available project keys. Try jira_search_issues() with a partial key.' jira_transition_issue: 'If transition is invalid for current status, returns error listing valid transitions.'
• Expand tool descriptions to 100 - 200 chars. E.g., jira_search_issues: 'Search Jira issues using JQL. Returns up to 50 results with key, summary, status, assignee. Use for discovery before reading individual issues. Requires valid JQL syntax.'
