Review comments at @crates/tinytools-agent/src/parse/test/regressions.rs:
- Line 130: Replace the inequality assertion in the regression test with
assert_ne!, comparing calls[0].source against CallSource::Native.
Review comments at @crates/tinytools-std/src/detect_tools/mod.rs:
- Line 53: Update the candidate construction in the executable lookup flow to
detect when name already ends in a recognized PATHEXT extension and probe it
unchanged. Append PATHEXT extensions only for extensionless names, preserving
the existing lookup behavior otherwise.
Review comments at @crates/tinytools-std/src/detect_tools/test.rs:
- Line 1: Prepend a concise module-level `//!` description of the PATH-detection
tests to the test module in this file, before the existing lint attribute.
- Line 1: Remove the module-wide lint allowance in the test module. Update
fallible tests to return Result and propagate errors with ?, and compare JSON
values directly where possible instead of unwrapping array conversions; keep the
fix scoped to these tests.
Review comments at @crates/tinytools-std/src/file_state/test/mod.rs:
- Line 1: Add a concise module-level `//!` description at the start of this test
module, describing the file-state tests and their purpose.
- Line 1: Remove the blanket Clippy allowance from the test module in mod.rs and
update any affected unwrap or expect calls in its child modules and tests to use
explicit checks or fallible test returns.
Review comments at @crates/tinytools-std/src/file_state/types.rs:
- Around line 89-90: Update the `writes` tracking used by `paths_written_by` so
latest-writer metadata remains available for staleness checks while per-agent
write history separately retains every agent that wrote each path. Ensure
`record_write` records each writer without discarding earlier attribution, and
add a regression test showing that after two agents write the same path,
querying for the first agent still returns that path.
Review comments at @crates/tinytools-std/src/lib.rs:
- Line 10: Update the crate-level documentation near the detect_tools overview
to include a short, runnable rustdoc example demonstrating the primary entry
point detect_tools::find_on_path. Keep the example focused on the crate’s
existing API and ensure it compiles as a documentation test.
Review comments at @crates/tinytools-std/src/url_guard/mod.rs:
- Around line 244-247: Update extract_host and extract_port to reject
backslashes before validating the URL, preventing their authority parsing from
disagreeing with WHATWG clients. Also reject percent-encoded characters in the
authority so encoded host characters cannot bypass validation.

Replaced a manual inequality assertion with the dedicated `assert_ne!` macro to improve readability and align with standard Rust testing conventions. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Remove several type definitions in the collapse module that were no longer referenced anywhere in the codebase, cleaning up dead code and reducing compilation overhead. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduce a `validate_actions` function that checks for an empty action list, duplicate action names, and member tools that declare a reserved `action` parameter, returning a structured `CollapseError` on failure. This ensures the collapsed tool is well-formed before use, preventing silent misconfiguration. The `CollapsedAction` type and error enum are moved to a dedicated `types` module for clarity, and the module-level documentation is updated to reflect the per-action classification model.

Move the write-recording logic from the free function `record_write` into a method on `FileStateCoordinator` so that the coordinator can also maintain a `written_paths` set. This set preserves every path an agent has ever written, even when another agent later overwrites it, enabling `paths_written_by` to return accurate historical attribution. The test helpers are updated to call the new method directly instead of manipulating internal state. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add comprehensive tests for the per-call permission and external effect resolution in collapsed tools, covering argument-aware classification, member selection, and edge cases like missing members and conflicting schemas. Also include validation tests for empty families, duplicate actions, and reserved properties. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `Tool` type is referenced in documentation comments but not used in code, so it is now imported only under `#[cfg(doc)]` to suppress an unused-import warning in non-doc builds. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…writes The `record_read` function now accepts a `read_started` instant that must be captured before the file is opened, rather than using `Instant::now` after the read completes. This ensures that a write from another agent that lands while the read is in flight is correctly ordered after the read and reported as stale, instead of being silently absorbed. The change also moves the read recording logic into a `FileStateCoordinator` method and updates the `ReadStamp` documentation to clarify the timestamp semantics.

Handle the case where a URL string cannot be parsed by returning an error instead of panicking, ensuring the function gracefully rejects invalid input rather than crashing. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The URL guard module previously panicked when encountering URLs with invalid characters or structure.

Updated test module imports in three files to use `crate::` paths instead of relative imports, ensuring consistent module resolution across the codebase. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The rewrite_local_refs function had a let-else chain that was incorrectly formatted, causing the reference rewriting logic to be nested inside the if-let block instead of being executed when both conditions matched. The fix restructures the conditional to use a proper let chain with the && operator, ensuring the reference is only rewritten when both the $ref key exists and its value starts with the expected prefix. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Convert several tests in detect_tools and url_guard to return `anyhow::Result<()>` instead of panicking on errors, and remove the unnecessary `Ok(())` from a test that already had the return type but did not need it. This makes test failures produce cleaner error messages and aligns the codebase with modern Rust testing conventions. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test `default_and_metadata_contracts_are_available` was calling `DetectToolsTool::default()` which could be ambiguous when multiple `Default` implementations exist. Changed to the fully qualified syntax `<DetectToolsTool as Default>::default()` to ensure the correct trait method is invoked.

…namespace collisions
The `rewrite_local_refs` function was rewritten to only descend into JSON Schema keywords that contain subschemas, rather than recursing into every object value. This prevents rewriting `$ref` strings that appear inside `const`, `enum`, `default`, or `examples`, which are instance data and must be left untouched. Additionally, the namespace format for merged `$defs` keys was changed from `{action}_{name}` to a length-prefixed encoding that guarantees unique keys even when action and definition names could produce collisions, such as `read_file` with `Options` and `read` with `file_Options`.

The rewrite of local $ref values now correctly decodes and re-encodes JSON Pointer tokens when namespacing definition references. Previously, references pointing to nested paths like `#/$defs/Options/properties/id` would lose the suffix after the first path segment, causing broken references after merging. The change adds decode and encode helper functions to properly handle tilde-escaped characters in pointer tokens. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
When the suffix in a local reference was empty, the previous code would produce a trailing slash in the generated `#/$defs/` path, resulting in an invalid JSON Pointer. The change now checks for an empty suffix and omits the slash separator, ensuring references are correctly formed regardless of whether a suffix is present.

For a URL with a trailing-dot hostname such as https://example.com./, extract_host strips the dot while url remains unchanged, so the new host field is example.com but the HTTP client's request authority is example.com.. A caller following the documented resolve_to_addrs(&host, &addrs) pattern therefore installs an override under a different hostname, allowing the client to perform a second DNS lookup and reopening the rebinding window. Fresh evidence beyond the earlier pinning fix is this newly exposed normalized host; either normalize the returned URL authority identically or return the exact hostname key the client will resolve.

When a valid local reference uses URI-fragment encoding, such as #/$defs/A%20B for a definition named A B, this passes the literal token A%20B to namespace_definition, while the copied definition is namespaced from the decoded key A B. The emitted reference consequently targets a nonexistent definition. Fresh evidence beyond the prior nested-pointer correction is that URI percent-decoding must occur before JSON Pointer ~ decoding; parse and re-encode the fragment when rewriting these references so the implementation continues to satisfy the documented no-dangling-reference contract.

Moves host-independent tool helpers out of OpenHuman into this workspace. There are two parts: three vocabulary-level helpers in
tinytools, and a newtinytools-stdcrate. The crate came in by merging the stacked #33 into this branch.tinytools(vocabulary crate, no new dependencies)collapseserves a family of tools as one action-dispatched tool:CollapsedAction,merge_action_schemas,resolve,unknown_action_messageandargs_without_action.Toolcontract. The argument-free permission is the minimum any member needs (minimum_permission). The per-call answers (permission_for_args,external_effect_for_args) come from the selected member's own argument-aware methods. An unresolvable action falls back tostrictest_permissionorany_external_effect.anyOf, so no member's constraints are lost.validate_actionsreturnsCollapseErrorfor an empty family, a duplicate action, or a member declaring the reservedactionproperty.deferral:strip_deferred_from_visibleanddeferred_tool_names.command_output:render_command_failure,command_failureandsandbox_exit_code.tinytools-std(new crate)This crate sits outside the dependency-light vocabulary crate.
