rebar
Rebar can block work until an AI plan review passes, require signed completion verification before close, and reconcile its event-sourced ticket record with Jira across CLI, Python, and MCP. GitHub is a read-only mirror. Code review runs in Gerrit.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
50/50 tools missing one or more hints — review_ticket (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); review_code (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scan_spec (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +47 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — unlink_tickets deletes at line 232 (rebar.unlink(id1, id2))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
47/50 tool handlers declare input schemas (94%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 5/50 tool handlers wrap calls in try/catch (10%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
