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

72/72 tools missing one or more hints — get_weather (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_notes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); send_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +69 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.

Descriptions match behaviour

5 tools describe read intent but their handlers mutate — git_log (line 28: result = subprocess.run(["git", "-C", real_path, "log", "--oneline", f"-n{count}"], capture_output=T); git_log (line 29: result = subprocess.run(cmd, shell=True, capture_output=True, text=True)); search_issues (line 15: result = subprocess.run(cmd, shell=True, capture_output=True, text=True))

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

Tool inputs are validated

67/72 tool handlers declare input schemas (93%)

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

Tool handlers catch errors

Only 24/72 tool handlers wrap calls in try/catch (33%)

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

19 child_process calls — runs shell commands

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

Tool description accuracy

5 tools have description/behavior mismatches: git_log: description implies read-only but handler writes/deletes/executes; git_log: description implies read-only but handler writes/deletes/executes; search_issues: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
