fix(claude_code): surface structured stdout errors on nonzero exit by senamakel · Pull Request #363 · tinyhumansai/tinyagents

senamakel · 2026-10-10T00:50:59Z

What

When the claude CLI exits nonzero, run_turn bailed with exit <code> stderr=<stderr> before looking at the structured error the CLI had printed on stdout. Most CLI failures (bad auth, unknown model, invalid session) put the reason on stdout and leave stderr empty, so the caller saw exit Some(1) stderr=.

On a nonzero exit, return the stdout result/error message when there is one, sanitized (configured API key and sk- tokens redacted) and bounded to 2 KiB. Fall back to bounded stderr only when stdout carried no error.
EventMapper now takes the reason from result.result when a result event has subtype=error or is_error=true, instead of the generic "claude reported result.subtype=error" text. Note this means an is_error=true result is now treated as a failed turn even on exit 0.
Updates the dependency_boundary ChatMessage line baseline for the shifted driver.rs lines (plus the new test reference).

Tests

Shell-script fake claude fixtures (unix only) in driver_tests.rs: error JSON + exit 1, error event + exit 2, stderr fallback, secrets stay out, bounded length; plus an EventMapper case.

cargo test -p tinyagents-harness --lib claude_code: 86 passed
With the stdout message ignored, the three stdout-error tests fail (checked); the stderr fallback test passes either way.
cargo test -p tinyagents-integration-tests --test dependency_boundary: 6 passed
cargo fmt --check -p tinyagents-harness, cargo clippy -p tinyagents-harness --all-targets: clean

Notes

Touches the same block as #360 (stale-session recovery) and #361; expect a small mechanical conflict in driver.rs and the baseline line numbers, whichever lands second. For tinyhumansai/openhuman#5712.

Summary by CodeRabbit

Bug Fixes
- Claude Code failures now show a structured error when available, or fall back to the command’s error output.
- Error messages include the exit code, redact configured secrets and API-key-like tokens, and are limited in length.
- Failed results now display their provided error text, including when the result is marked as an error despite a success subtype.

The driver now prefers the CLI's structured stdout error message over stderr when a turn exits nonzero, since most failures such as bad auth or unknown models are reported there with stderr left empty. Messages are sanitized to redact the configured API key and any sk- tokens, and are bounded in length. The event mapper also treats is_error=true results as failures and carries the human-readable reason through. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Add a test asserting that a result event flagged as an error surfaces its result text as the mapper's error, guarding the mapping against regressions. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The recorded line counts for the claude code driver debt entries were stale after the files grew, and a new entry was added for driver_tests.rs. The boundary test now matches the current sources instead of failing on the shifted line numbers. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Tiny Sweeper review

This PR makes the claude_code driver surface the CLI's structured stdout error on nonzero exits instead of relying on often-empty stderr, with secret redaction (configured API key and sk- tokens) and a 2 KiB length cap on the stdout paths. Earlier findings about sanitizing structured stdout errors on both nonzero and zero exits are addressed with tests that would fail on regression. One finding remains active across lanes: the stderr fallback in nonzero_exit_message is still emitted raw — neither redacted, sk--scrubbed, nor bounded — so a credential or oversized dump on stderr still reaches the returned error.

What changed

When the claude CLI exits nonzero, the driver now prefers a sanitized structured stdout error (via sanitize_cli_message and nonzero_exit_message) and falls back to stderr only when stdout carried none — but that stderr fallback remains raw and unbounded. The event mapper captures the human-readable reason from result events with is_error=true, and the successful-exit is_error bail is sanitized too.

Features

Modified — Structured stdout error surfaced on nonzero exit: Failures such as bad auth or unknown model now report the CLI's human-readable stdout error (e.g. 'Invalid API key - please run /login') with the exit code, instead of a possibly empty stderr message. (crates/tinyagents-harness/src/providers/claude_code/driver.rs#pub(crate) async fn run_turn(ctx: TurnContext<'_>) -> anyhow::Result<ChatRespons, crates/tinyagents-harness/src/providers/claude_code/driver.rs#fn push_bounded(acc: &mut String, chunk: &str, max_bytes: usize) {)
Added — Sanitization and bounding of CLI stdout error text: Error text from stdout redacts the configured API key (including inside larger tokens) and any sk- style key after separators, and is capped at STDOUT_ERROR_CAP (2 KiB), reducing secret leakage and oversized errors. (crates/tinyagents-harness/src/providers/claude_code/driver.rs#fn push_bounded(acc: &mut String, chunk: &str, max_bytes: usize) {)
Modified — Event mapper extracts is_error reason: A failed turn reported as subtype=error or is_error=true with a non-empty result string now carries that reason as the error message rather than a generic placeholder. (crates/tinyagents-harness/src/providers/claude_code/event_mapper.rs#impl EventMapper {)
Modified — Sanitized is_error bail on successful exit: The zero-exit is_error bail path now passes through sanitize_cli_message, applying the same redaction and cap as the nonzero-exit path. (crates/tinyagents-harness/src/providers/claude_code/driver.rs#pub(crate) async fn run_turn(ctx: TurnContext<'_>) -> anyhow::Result<ChatRespons)

Tests

unit — A fake claude script exits nonzero after printing a structured result error; the driver error must contain the stdout reason and the exit code.: Covers the primary nonzero-exit structured-error path end to end via a fake binary. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — Nonzero exit with a type=error event surfaces the event message; nonzero exit without stdout error falls back to stderr text.: Covers the error-event variant and the stderr fallback branch; no test asserts redaction or bounding on the stderr fallback. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — A stdout error containing an sk- key and the configured API key is redacted in the returned error.: Asserts both secret types are absent from the surfaced error text. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — nonzero_exit_message output is bounded below STDOUT_ERROR_CAP + 128 for very long stdout errors.: Verifies the length cap on the stdout-error path; no equivalent test covers the stderr fallback length. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — sk- keys after separators (=, :, quotes, URL query) are redacted while 'task-force' and bare 'sk-' are untouched.: Exercises the redaction boundary logic including false-positive avoidance. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — A configured API key embedded inside larger tokens is redacted.: Verifies substring replacement of the configured key. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — Zero exit with is_error=true result containing secrets and a 5,000-char payload yields a sanitized, bounded error.: Covers the successful-exit is_error bail path including redaction and cap. (crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs#fn the_shape_of_the_line_is_reported() {)
unit — An event mapper result event with is_error=true and a result string sets self.error to that reason.: Verifies the mapper-level reason extraction. (crates/tinyagents-harness/src/providers/claude_code/event_mapper_tests.rs#fn final_assistant_message_is_skipped() {)

tests

Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The revision sanitizes and bounds every path that turns CLI output into a returned error: the nonzero-exit structured stdout message, the stderr fallback, and the zero-exit `mapper.error` are all routed through `sanitize_cli_message`, which redacts the configured key and `sk-` style keys via a boundary-aware scanner and caps output with the existing UTF-8-safe `push_bounded`. Each prior finding (sanitize on every return path, redact secrets in structured tokens, sanitize successful exits, bound the stderr fallback) is addressed and pinned by tests that would fail on regression, including end-to-end fake-CLI tests. The `is_error=true` and object-shaped `error` payload changes each have a focused test. The change looks sound and safe to merge. _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

📝 Walkthrough

Walkthrough

The event mapper now captures error text from failed result events. For nonzero Claude CLI exits, the driver prefers sanitized structured stdout errors, limits their length, and falls back to trimmed stderr when no usable stdout error exists.

Changes

Claude Code Error Reporting

Layer / File(s)	Summary
Capture errors from result events `crates/tinyagents-harness/src/providers/claude_code/event_mapper.rs`, `crates/tinyagents-harness/src/providers/claude_code/event_mapper_tests.rs`	The mapper records nonempty result text when a result is marked as an error and no error is already set. A test covers an error-marked result with a success subtype.
Format nonzero-exit errors `crates/tinyagents-harness/src/providers/claude_code/driver.rs`, `crates/tinyagents-harness/src/providers/claude_code/driver_tests.rs`, `crates/tinyagents-integration-tests/tests/dependency_boundary.rs`	The driver prefers sanitized structured stdout errors, limits them to 2,048 bytes, and falls back to trimmed stderr. Tests cover error sources, sanitization, and message length. The dependency-boundary debt baseline is updated.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 385ea

Error messages from the Claude CLI may leak API-key-like text or exceed the size limit when the CLI exits with status 0 or embeds a key in a token. The impact is limited and the fixes are small, so address both before or shortly after merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 385ea

Useful failure details now reach callers, but credential removal is incomplete and depends on the process exit status. The exposure concerns credentials included in failure messages; the change does not add execution privileges.

Retained concerns

Low · security · observed: Newly captured result-event reasons bypass credential redaction and the 2 KiB diagnostic cap when the process exits successfully. The provider preserves this raw text in returned errors and failure stream items. Previously, subtype-error results used a generic message, and is_error=true alone did not activate this failure path.
Low · security · observed: The new nonzero-exit diagnostic boundary leaves nonconfigured sk- credentials unchanged when embedded inside a whitespace-delimited token, such as key=sk-… . Exact replacement protects the configured API key, but the independent token check only recognizes trimmed tokens starting with sk-. Such stdout content was not previously returned on nonzero exits.

Security review details

Security Blast Radius

inferred — The supported exposure is credential-bearing CLI diagnostic text reaching provider failure-message consumers. A configured credential is supplied from the provider instance across its calls, so credential scope need not be limited to one thread. Tenant breadth, credential permissions, and deployment-specific retention or delivery are not established.

Security Findings and Attack Paths

observed — The retained findings correspond to two reachable disclosure paths: newly captured result reasons returned raw on exit zero, and embedded nonconfigured sk- credentials surviving nonzero-exit sanitization. Disclosure requires sensitive material in CLI diagnostics; direct unauthenticated control of those diagnostics was not demonstrated.

Trust Boundaries and Controls

observed — The relevant transition is from subprocess diagnostic data into application failure messages. Tests cover configured-secret removal and standalone sk- tokens on nonzero exit, but do not establish redaction for embedded tokens or the newly expanded exit-zero path.

Resilience and Maintainability Implications

observed — The adapter serializes turns for the same thread before acquiring a global concurrency permit. Error returns retain the existing lock and permit lifecycle; the PR does not introduce a new shared-state concurrency mechanism.

Hardening Proposals

proposed — Apply one credential-removal and length-limiting policy to all CLI diagnostic returns, independent of exit status. Include embedded credential forms and exit-zero failed-result cases in regression coverage.

The stream parser only read the error field when it was a plain string, so error events whose payload is an object fell back to a generic message and lost the real reason. It now also looks inside the object's message field, and a driver test confirms the surfaced text is still redacted. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Read failure details from the result errors array

When Claude returns a failed result with diagnostics only in errors—for example, error_during_execution or error_max_turns—this probes only result and replaces the real reason with the generic subtype message. The official ResultMessage contract exposes errors and specifically documents execution-error reasons there (Claude Agent SDK reference); on a nonzero exit, that generic value is then preferred over even a useful stderr message. Extract and sanitize the nonempty errors entries before using the generic fallback.

✅ Action performed

Comments resolved and changes approved.

Keeps #363's sanitized structured stdout errors and #360's missing-session recovery, which now checks both stderr and the mapped error before bailing. Co-authored-by: Medulla <medulla@tinyhumans.ai>

Resolve conflicts with #360 (stale-session recovery) and #363 (stdout errors): keep both sides' tests, move remove_if into SessionStore so it uses the delivered-turn store's locking and persistence, and have it drop the thread's delivered-turn record with the mapping (a replacement session has received nothing). Add a regression test for that and refresh the dependency_boundary line baseline. Co-authored-by: Medulla <medulla@tinyhumans.ai>

test(claude_code): cover error result carrying its reason

d973239

Add a test asserting that a result event flagged as an error surfaces its result text as the mapper's error, guarding the mapping against regressions. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
