From af3354c70884b46132e4b1f63100a77456635552 Mon Sep 17 00:00:00 2001 From: Doar <2508356590@qq.com> Date: Wed, 21 Oct 2026 11:43:33 +0800 Subject: [PATCH 1/6] feat(evaluation): measure agent recovery from failed MCP calls Add evaluation/agent_tool_recovery: nine cases covering the six failure classes of #2067, run against disposable real Servers through the real MCP mount, with a fault gateway, Claude Code and Codex adapters and their plugin variants, content-free scoring, and per-operation remediation rows. Commit the content-free results of 108 real sessions and run the offline tests in evaluation-unit-test.

Violations are identical retries beyond the case's allowance, named-field violations, writes +after a terminal failure, and a final-state check such as a duplicate Scope.

Owning boundary: the Dream request model's validator and its Server mapping. +2. **`propose_experience`: `details: null` although the Server knows the field.** In five of six Claude Code + sessions of `mcp-family-rejected`, the model proposed a revision without the target in `artifact_refs` and + received 422 `invalid_request` with no details. The rejection is + `InvalidCandidateError("artifacts", "must include the exact target experience Artifact")`, which + `_map_candidate_error` maps without its field. Each session retried with changed arguments once or twice, eight + blind retries in all; two sessions found the accepted shape. Replaying the same arguments with the target revision in `artifact_refs` on a + disposable Server returns 201. Owning boundary: the Server's Candidate error mapping. +3. **`capture_working_note`: a past `expires_at` returns 422 without the field.** Nine sessions sent the past + expiry and received "The request is invalid." with `details: null`. `claude-code-plugin` and `codex` inferred the + cause from the timestamp; `codex-plugin` reported the 422 and stopped without a correction. In the `claude-code` + baseline the model noticed the past expiry before calling. Owning boundary: the Server's + invalid-request mapping (`_invalid_request_details`). + +These three changes add the exact field and a stable reason to the error details. They change the HTTP response +contract and belong in follow-ups through the OpenAPI process. [remediation.json](remediation.json) holds one row +per operation with the pooled runs, repeated calls, retries after a change, and transcript hashes; no row records an +unchanged resend after its failure. + +### Retry-later failures abandoned by Codex + +4. **`search_memory` and `create_scope` after a transport failure.** Codex abandoned all twelve sessions of + `transport-reset-read` and `idempotent-replay`, with and without the plugin; Claude Code recovered in all twelve, + resending the read or the keyed create, or first confirming with `list_scopes`. Codex reported HTTP 502 or an + unconfirmed outcome; in `idempotent-replay` the Scope had been created. The failure reaches Codex as its own + client's "Transport send error", which PowerContext does not produce. In `codex-plugin` the model read the + plugin's Skill first and behaved the same: the Skill says a timed-out write has an unknown outcome to inspect + before retrying, but not that a read, or a write with the same `idempotency_key`, can be resent. The candidate + boundary is host guidance (the Skill or the MCP tool descriptions); these runs do not show that added guidance + would change the model's behavior. + +### Plugin integration + +5. **The Codex plugin reports an authorization denial as a Scope-binding failure.** With the viewer credential, + `resolve_scope_binding` returns 403, and the PreToolUse hook (`hooks/bind_tools.py`) denies every PowerContext + call of the session as "could not resolve the current Scope binding". All three sessions told the user the + binding failed instead of reporting missing write permission. Owning boundary: the Codex plugin, or the Server's + authorization of binding resolution for read-only principals. The Claude Code plugin has no PreToolUse hook; the + same 403 only skips its context preparation. + +## No change indicated + +- `generate_experience` (503 `generation_unavailable`) and `remember_memory` (403 `forbidden`): every scored + session stopped after one call and reported the reason. +- `replace_artifact` (412 `revision_conflict` with `current_etag`): no session overwrote the newer revision. Claude + Code re-read it and asked the user; Codex reported the conflict and stopped. +- `approve_candidate` (409 `candidate_conflict`): models usually re-read the Candidate before approving; the + triggered sessions stopped without approving the newer version. +- `replace_artifact` for an Experience: the MCP guidance kept every model from calling it. +- `create_dream_run` 429 `capacity_exceeded`: Claude Code made at most one more attempt, then reported the pending + run or asked the user to retry later. MCP does not convey the HTTP `Retry-After` header; no session showed a + problem from its absence. + +## Plugin comparison + +The plugin rows load each repository plugin's hooks and Skill on top of the same MCP surface. They changed no +recovery outcome on the retry-later cases. The Claude Code model never invoked the plugin's Skill; the Codex model +read it in every session.
