fix(agent): a fetched site's HTTP status is not a credential failure - #6980
Conversation
…edential issues Add a `fetched_site_status` function that extracts the HTTP status code from `web_fetch` error messages, and update the failure classification so that a site's 4xx/5xx responses are treated as site-refusal or transient failures rather than credential problems. This prevents the agent from incorrectly pausing the run when a public website returns an HTTP error, while preserving the existing credential-failure behaviour for other tools and for bare status text.

The repeated failure middleware now correctly classifies failures by checking the failure count against the threshold, rather than always classifying as a repeated failure. This fixes incorrect behavior where the middleware would mark failures as repeated even when the count was below the threshold. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
… and tests Reformat several multi-line expressions in the repeated failure middleware and its test file to improve readability by breaking long lines at natural boundaries. No functional changes are introduced. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…cated module Move the `fetched_site_status` function, `WEB_FETCH_TOOL` constant, and related site-status policy logic from `repeated_failure.rs` into a new `fetched_site` module, keeping the failure-classification middleware focused on its core responsibility. The extracted functions are re-exported and used from the new module, with the test file updated to reference the new location. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
…ed_site module Move the web_fetch-specific host scoping and recovery policy logic from the repeated_failure module into the fetched_site module, where it is more cohesive. The new functions accept the tool name and relevant fields directly, returning None when the error is not a web_fetch result, so callers no longer need to check the tool name themselves.

- Around line 315-317: Update after_tool to exclude response-body excerpts from
terminal-inference and recoverable-failure checks for ordinary fetched-site

fetched_site_policy handling for classified policies and add an after_tool test
where a 404 excerpt contains “timed out.”

…ures When a web fetch returns an ordinary HTTP error status like 404 or 410, the response body may contain words such as "timeout" that would cause the middleware to misclassify the failure as a transient tool error or terminal inference failure. This change introduces a heuristic that extracts only the first line of the failure text for such status codes, keeping the full text for the exact-repeat tracker while preventing misleading classification of ordinary site failures. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Move the logic that truncates failure text for fetched-site responses into a new `heuristic_text` function in `fetched_site.rs`, replacing the inline code in `repeated_failure.rs`. This reduces duplication and makes the heuristic available for reuse elsewhere. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Summary
RepeatedToolFailureMiddlewareno longer treats a public website's HTTP status as a credential failure of OpenHuman's own when it comes fromweb_fetch.site_refusedclass (2 retries, scoped per host); 429/5xx join the existingtransientclass; 404 and other statuses stay ordinary tool failures.web_fetchfailures are scoped by host rather than by page URL, so a model walking a blocked site's pages shares one budget.web_fetchreturn 4xx/5xx as error results. Merge this PR before thevendor/tinytoolspin moves to include feat: accessibility automation v1 (core + tauri + settings) #47. This PR moves no gitlink;vendor/tinyagentsmatches openhumanmain(a08a8d50), whose nested tinytools (8e5008c3) predates feat: accessibility automation v1 (core + tauri + settings) #47. Works with the current pin (pure text and tool-name matching).Problem
tinytools#47 makes
web_fetchreturnHTTP 403 Forbidden from <host>; the site refused the request. Try another source.as an errorToolResult.recovery_policysends error text throughtools::status::classify, which maps403/forbiddentoBadCredentials, i.e.("authentication", 0). Once the gitlink is re-pinned, one bot-blocked website would pause the whole run. The same keyword sniffing would also read words in the quoted response excerpt.The existing test
varied_queries_against_one_forbidden_endpoint_stop_on_first_failureprotects the zero-retry behaviour for credentialed endpoints, where a 403 does mean the account lacks a grant. It still passes: a bare403 Forbiddenfromweb_fetchis unchanged, and the exemption needs the fullHTTP <code> <reason> from <host>;shape.Solution
Chosen design: recognise the tinytools#47 error shape, gated on the tool name, in a new
middleware/fetched_site.rs, and give 401/403 their own class in the breaker's ledger (class x tool x scope).fetched_site_status: anchored at the start of the text and requires the wholeHTTP <4xx|5xx> <reason> from <host>;shape. A bareHTTP 403,403 Forbidden, or a status quoted later (response excerpt, command output) does not match.fetched_site_policy: applies only whentool == "web_fetch", so the same words from an account-bound tool (e.g. Composio) are stillauthentication, 0 retries. Returns before any keyword sniffing, so the response excerpt cannot steer the class.("site_refused", 2); 429 and 5xx ->("transient", 2); 404/410/other ->None(ordinary failure, exact-repeat guard).failure_scope: forweb_fetchtheurlis scoped by host, so repeated refusals from one host stop the run after the budget regardless of path/query, and different hosts count separately.site_refusedis cleared by a successful observation like the other classes.tools::status::classify(no tool name there, and UI copy for a web_fetch 403 still says "sign in again"; worth a follow-up),http_request(its error is a bareHTTP <code>with no host and it is used with caller-supplied credentials), and the web search family (provider errors there can be our own API key).example.test) rather than the page path; its behaviour assertions (pause on first failure,authentication, no query leak) are unchanged.Submission Checklist
Closes #NNN- N/A: companion fix, references openhuman: web research budget clears every tool and forces a final answer, ending coding turns with no edits #6959 belowImpact
Core agent loop only (breaker policy). A site-blocked fetch no longer ends the run; the model gets the tool's guidance and moves to another source. Runs still stop after the third refusal from the same host. Fetch-failure scope changed from per-URL to per-host, which also makes the existing transient/timeout budget for
web_fetchper host.Related
