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

49/49 tools missing one or more hints — ssh_container_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ssh_container_logs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ssh_container_exec (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +46 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

9 tools describe read intent but their handlers mutate — ssh_container_list (line 18: session.connection.exec(); ssh_container_logs (line 18: session.connection.exec(); ssh_find (line 18: session.connection.exec()

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

Tool inputs are validated

48/49 tool handlers declare input schemas (98%)

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

Tool handlers catch errors

48/49 tool handlers wrap calls in try/catch (98%)

Wrap each tool handler body in try/catch and return a structured error response.

Tool test coverage

Only 0/49 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

10 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

10 tools have description/behavior mismatches: ssh_container_list: description implies read-only but handler writes/deletes/executes; ssh_container_logs: description implies read-only but handler writes/deletes/executes; ssh_find: description implies read-only but handler writes/deletes/executes

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