Tool annotations

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

79/79 tools missing one or more hints — rba_ws_start (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); rba_ws_stop (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); rba_ws_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +76 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

11 tools perform destructive updates without destructiveHint — rba_development_snapshot deletes at line 1946 (fs.rm(tempPath, { force: true })); rba_agent_bootstrap deletes at line 1767 (fs.rm(temporaryPath, { force: true })); rba_execute_file deletes at line 1946 (fs.rm(tempPath, { force: true }))

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.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — rba_script_preflight (line 1923: fs.mkdir(tmpRoot, { recursive: true }))

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

64/79 tool handlers declare input schemas (81%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

61/79 tool handlers wrap calls in try/catch (77%)

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.

Shell command execution

1 child_process call — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.21.0 (high), @modelcontextprotocol/sdk@1.21.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
