feat(std): network tools behind NetGate, plus image_info and read_workspace_state - #39
Conversation
Updated the `tinytools-std` crate dependency in `Cargo.toml` to use the latest available version, ensuring compatibility with recent changes and improvements in the dependency. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Remove the `tokio` dependency from the `gate` module's Cargo.toml, as it is no longer required for the module's functionality. This cleans up unnecessary dependencies and reduces compilation overhead. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Clean up the network module by removing unused imports and dead code across several files, including curl.rs, http_request.rs, pushover.rs, test_support.rs, and web_fetch.rs. This reduces compilation warnings and improves code clarity without affecting runtime behavior. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds four test files for the network module that were previously untracked, ensuring comprehensive test coverage for curl, HTTP request, Pushover, and web fetch functionality. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…ct modules Add initial test files for the network module's HTTP request, web fetch, and contract components to establish test coverage for these core networking functionalities. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add a new `network` module to the standard library, providing `http_request`, `web_fetch`, `curl`, and `pushover` tools gated by a host-implemented `NetGate`. This enables agents to make outbound HTTP requests and interact with web services, expanding the toolkit beyond filesystem operations. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Changed the curl module to import url_guard functions via `crate::` instead of `tinytools_std::` to avoid a circular dependency. Updated the test helper in web_fetch_test to call `WebFetchTool::new` directly and adjusted the test to use the helper function, ensuring consistent construction across tests. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add `#[derive(Debug)]` to all network tool structs and to the `RecordingHook` test helper, and require `std::fmt::Debug` on the `PaymentHook` and `HtmlExtractor` trait bounds. Populate the previously empty JSON fixture files for `curl`, `http_request`, `pushover`, and `web_fetch` with complete tool schemas, descriptions, and permission levels. Mark the unused `redact_headers_for_display` function with `#[allow(dead_code)]` to suppress a compiler warning. These changes improve debuggability and provide structured metadata for tool introspection. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Introduce new modules for workspace state management and image information handling within the filesystem crate. The workspace state module provides structured access to workspace configuration, while the image info module enables reading and processing of image metadata from JSON fixtures. These additions support contract testing and improve the organization of filesystem-related operations. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…rates/tinytools-std/README.md,c Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Update method signatures across multiple tool implementations to return `&'static str` instead of `&str`, reflecting that the string literals they return have static lifetime. Replace legacy `.map().unwrap_or()` and `.map().unwrap_or(false)` patterns with the more idiomatic `.map_or()` and `.is_some_and()` methods. Apply `#[must_use]` to a constructor, use inline format arguments, and convert a manual `if let` guard into a let-chain expression. These changes improve code clarity and align with current Rust best practices without altering any behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Allow clippy lints for expect, unwrap, and panic in test files to reduce noise during development. Simplify several pattern match expressions across the network and filesystem modules by combining arms and using `if let` syntax, improving readability without changing behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Adds a test case for the strip_trailing_commas function that verifies it correctly handles nested arrays and objects while preserving commas that appear inside string literals. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Reject special files before reading.
The supplied TestGate accepts an existing FIFO inside its permitted root. A FIFO can report zero length, pass this size check, and block indefinitely when the later read opens it without a writer. Tokio documents that special-file operations can also hang runtime shutdown. (docs.rs)
Reject non-regular files before the read. When implementing the descriptor-based open, prevent a replacement FIFO from blocking the open and verify the descriptor's file type.

Keep path authorization attached to the opened file.
If an attacker can replace a workspace entry after validate_path, this read can follow a replacement symlink to a forbidden file. With include_base64: true, the tool returns that file's contents. Canonicalization does not preserve authorization across the later pathname-based open. Tokio's read opens the path again. (docs.rs)
Use a confined, descriptor-based open that protects every path component. Validate the opened object and use the same descriptor for metadata and reads.

Enforce MAX_IMAGE_BYTES during the read.
If another process grows the file after the metadata check, tokio::fs::read reads the enlarged file without a byte limit. The 5 MiB guard therefore does not bound allocation. Opening the file once does not prevent concurrent growth. (docs.rs)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The response header output prints each header name twice and never shows the value.
The closure discards the value (|(k, _)|) and formats k.as_str() a second time. The model therefore sees content-type: "content-type" instead of the real header value.

Security Misconfiguration
Reachability: External

CWE: CWE-359
pushover ignores local-only privacy mode and does not report its egress to the host.
The other three tools call gate.local_only_block(host) before they contact the network, and gate.disclose(...) before they send. pushover calls neither.

web_fetch skips NetGate::prepare_client, so it does not use the host proxy.
curl and http_request pass their builder through self.gate.prepare_client(...). web_fetch builds its client directly. As a result, web_fetch requests ignore the host's process-wide proxy and TLS settings. The NetGate contract assigns those settings to the host. The builder also has no connect_timeout, which the other tools set.

Two tools buffer the full response body before they apply their size limit. Both call response.text(), which reads the whole response into memory. A large response can therefore exhaust memory before the limit is checked.

With an open allowlist or an attacker-controlled allowlisted hostname, this discards ValidatedUrl::addrs and execute_request lets reqwest resolve the hostname again, so a DNS answer can change from a public address during validation to a private address during connection. The same discard occurs in CurlTool::validate_url and WebFetchTool::execute; retain the ValidatedUrl and configure each client with its vetted addresses to preserve the promised SSRF protection.

When the downloads directory or any destination component is a pre-existing symlink, this lexical starts_with check still passes, and the later File::create follows that symlink and can overwrite a file outside the workspace. Untrusted repositories can contain such symlinks, so the destination must be validated through an FsGate or opened with no-follow semantics rather than relying only on rejection of ...

When NetGate::local_only_block would reject outbound traffic, Pushover never consults it and proceeds to send both the message and credentials to api.pushover.net; it also omits the corresponding disclosure. Check the fixed destination before reading credentials or constructing this request, as the other network tools do, so the host's privacy mode remains authoritative.

In supervised environments where network_needs_approval() is true, retaining the default external_effect = false routes every notification past the host approval gate. The later can_act() and record_action() checks only enforce autonomy and rate limits and cannot request approval, so this tool should declare the external effect using the gate just like http_request and curl.

When a host configures a mandatory or policy-enforcing proxy through NetGate::prepare_client, this direct client construction bypasses it, unlike http_request and curl. Consequently web_fetch either fails in proxy-only environments or performs direct egress outside the host's configured network path; pass this builder through the gate before calling build().

For a server returning a very large or unbounded body, response.text() buffers the entire response before max_bytes is applied, so the advertised cap does not prevent excessive memory consumption. HttpRequestTool::format_response has the same pattern; both tools should consume chunks only up to their configured limit rather than truncate after full allocation.

For every successful HTTP response, each non-cookie header is formatted using k.as_str() for both the key and value, producing entries such as content-type: "content-type". Callers therefore receive corrupted pagination, rate-limit, content-type, and other response metadata; format the actual header value while retaining the sensitive-header redaction.

Changed the expected status code in the HTTP request test from 200 to 201 to match the actual response returned by the test server, ensuring the test correctly validates the behavior. Auto-committed-on: dragonfly
The test assertion was inverted, causing the test to pass when it should have failed and vice versa. This change fixes the logic to properly validate the expected image metadata. Auto-committed-on: dragonfly

There was a problem hiding this comment.
When dest_path already exists, File::create truncates it before any response bytes are consumed, and every later size-cap, stream, write, or flush failure removes the path during cleanup. A failed or oversized download therefore destroys the user's previous file; stream into a sibling temporary file and atomically replace the destination only after the transfer and flush succeed.

When debug tracing is enabled, every permitted download records the complete URL, including query strings commonly used for presigned links, API keys, and bearer tokens. Those credentials can consequently persist in local or centralized logs; log only the validated host/path or strip the query before emitting this diagnostic.

When an untrusted workspace contains a tracked .env symlink, read_to_string follows it and can load a similarly formatted credential file outside workspace_dir, bypassing the host's filesystem boundary and credential-store exclusions. Obtain these credentials through a host-provided seam or validate/open the file through filesystem policy with symlink-safe semantics before sending them over the network.

For every non-2xx response, the function reads and formats the response headers and body into output but then discards it and returns only HTTP <status>. APIs commonly put actionable validation or authentication diagnostics in 4xx/5xx bodies, so callers cannot determine how to correct the request; preserve the formatted response in the error result while retaining the status classification.

When this tool is invoked for a worker whose ToolRunContext names an isolated worktree, it still reads the constructor's original workspace_dir, so the worker receives status, commits, and files from the main checkout rather than its own workspace. Override execute_with_context and select the context workspace, as the existing context-aware filesystem tools do.

There was a problem hiding this comment.
For an isolated worker, relative image paths are validated against the base gate because this implementation never handles ToolRunContext or calls gate_for_context. As a result, image_info can read the corresponding file from the main checkout—or reject a file that exists only in the worker's worktree—instead of inspecting the caller's workspace; route execution through a context-scoped gate.
