FULL coverage for one story (Jira issue key), including every step and execution. Use when assessing whether a story is well covered, well-formed, or passing. Returns a digested bundle: linked test cases with objective, priority, status, steps (action / expected result / data), each case's most recent execution, referenced test cycles, and a coverage summary (passed / failed / not-run counts and step-quality flags). Heavier than list_story_test_cases — if you only need the list/titles of a story's tests, use that instead. Read-only; returns empty coverage (not an error) when no tests are linked.

LIGHTWEIGHT list of the test cases linked to one story (Jira issue key) — each with key, name/title, priority, and status. No steps, no executions. Use this when asked for the test cases or titles of a specific story. Prefer this over search_test_cases (which is project-wide, not story-scoped) and over review_story_coverage (which is heavier) when you only need the list. Read-only; returns an empty list (not an error) when no tests are linked.

Returns the full detail of a single Zephyr test case, including ordered steps with expected results. Steps with an empty expected-result field are preserved so quality gaps stay visible. Read-only.

Returns the test executions linked to a Jira issue (story) with their status, cycle, and date — a focused pass/fail view. Returns an empty list when the story's tests have not been run. Read-only.

FULL execution history of ONE test case (Zephyr test case key), newest-first — every run across all cycles plus ad-hoc runs, not just the latest. Each execution includes status, cycle, date, comment, automated flag, timing (execution/estimated ms), who ran it, environment, custom fields, and linked Jira issues. Use this when asked about a specific test case's runs, history, or flakiness. This is TEST-CASE scoped — for the executions of a whole story (Jira issue key) use list_story_executions instead. Read-only; returns an empty list (not an error) when the test case has never been run.

PROJECT-WIDE search across ALL test cases in a project, matching key/name/objective (case-insensitive, client-side; the Zephyr API has no full-text search). This is NOT scoped to a story — do not use it to get the tests of a specific issue. Use it only when you do NOT have a Jira issue key, or to look beyond the tests linked to a single story. For a story's tests, use list_story_test_cases (titles) or review_story_coverage (full). Read-only.

Returns Zephyr project metadata (Zephyr id, Jira project id, key, enabled flag) for a project key. Useful to resolve keys and scope during a review. Read-only.
