Check the failing stage

Symptom	Check / next action
agentbench missing or importing an old checkout	Activate this checkout's .venv, check python -m pip --version, then python -m pip install -e .. From the root, python -m agentbench --help also checks local imports.
IDE cannot resolve kuma…	Install the plugin's requirements.txt in the host venv and select that interpreter. Docker's packages are separate.
Trace UI not built or incomplete	Use compatible Node (20.19+ on 20.x or 22.12+), then cd web, npm ci, npm run build. Open the actual saved result path.
Wrong Suite / URL	Use the complete printed View: URL including Suite ID and port. Python selects a free port if 8765 is occupied.
Newly printed Suite URL returns 404 on Windows	Update ABB and open the saved events.json with agentbench view. Older viewers could share an occupied port and send requests to a previous Suite. Restarting the viewer loads the fix; the benchmark can continue running.
Docker unavailable / permission denied	Run docker info as the same user. Start Desktop/Engine and inspect Docker context/permissions. Do not run ABB as root to hide ownership problems.
Python 3.10 Case generation reports missing tomllib / tomli	Update ABB and rebuild the evaluation image. Worker staging installs tomli for Python below 3.11 into the image's selected Python environment; installing it only on the host does not repair an existing image. See #85.
Every Docker Case fails in Case generation with ModuleNotFoundError: No module named 'filelock'	Update ABB and rebuild the evaluation image. Worker staging installs filelock into the image's selected Python environment because the injected Suite lock imports it; installing it only on the host does not repair an existing image. See #391.
Missing/invalid KUMA key	Nonempty KUMA_API_KEY takes precedence over DEFUZEX_API_KEY. Check exported variables overriding .env and service account access without displaying keys.
Missing model / quota / provider error	OPENROUTER_MODEL has no runtime default. Check the slug, account access, funds/limits and tool/protocol support. A key is not a model name.
agent add -b rejects model response	See Structured-output generation failures. Inspect field/JSON diagnostics, correction exhaustion and provider finish metadata.
Tool authentication error	The Agent must declare its required keys and the CLI environment must provide them. .env is not mounted wholesale.
Blocked route / trace rejection	Inspect the recorded host/path/protocol and declared routes. Fix source-backed route mismatches; do not disable observation or permit arbitrary traffic to obtain pass.
No ready Agents	Inspect agentbench observe --list and the registry. run selects enabled ready registrations; certify adapting integrations after dependencies work.
Judge model_invalid_result	Inspect SDK/report artifacts. Separate remote Judge output validation from the tested Agent's answer.
Blocked recovery	Preserve plan, request ledger and artifacts. Unconfirmed accepted requests, unsafe replay, permissions or incomplete cleanup may block retries. Do not duplicate paid requests blindly.

OPENROUTER_BASE_URL changes the model upstream; optional OPENROUTER_HTTP_REFERER and OPENROUTER_APP_TITLE identify requests. They do not change KUMA's endpoint. The onboarding catalog reads KUMA_BASE_URL, but evaluation does not forward it end to end and allows the default DefuzeX backend. Do not treat it as a working evaluation override: see #52.

Structured-output generation failures

Configuration generation with agent add -b validates model replies against each stage's full local schema. The diagnostic and correction paths address #112. Fenced/prose JSON tolerance (#89) is separate: such content must be corrected by the model rather than silently extracted.

Error	Current behavior	What to inspect
Model response schema mismatch	Bounded diagnostics include field paths, expected constraints and actual types; corrections receive those diagnostics and the previous parsed response.	response-N.json and validation-N.json; planning uses plan- prefixes, review uses review-N.json and review-validation-N.json.
OpenRouter model content is invalid JSON / must be a JSON object	Corrects the same stage using safe previous content and decoder line/column/offset or the actual root type. Malformed content is not saved.	Validation records hold safe diagnostics. The raw model content is kept only in memory for the correction request after credential checks.
OpenRouter returned an invalid structured response envelope	Invalid provider envelope or missing content stops without content corrections.	Check the provider configuration; this is distinct from JSON errors inside model content.
OpenRouter did not finish the configuration	A finish reason other than stop stops without content corrections.	provider-N.json and terminal build-result.json diagnostics include available finish reason, usage (including reasoning tokens) and content length. Confirm length before increasing output budgets.

Metadata records contain only selected finish reasons and numeric usage/length fields, not raw provider responses. A credential-bearing response is never saved or sent back. A review-format failure retries the review of the same candidate; actual compatibility issues can still require regenerating the file.

1. Use the attempt path printed by the failed build. Preserve build-result.json, plan-response-N.json / plan-validation-N.json when present, and the failing file's steps/<number>-<filename>/ directory. current_file identifies a file stage when available; planning can fail before that field is set. Keep valid completed integration files and the checkpoint for reuse.

2. Inspect saved parsed responses locally against the full local schema, not the reduced schema sent to the provider. File content uses agentbench/onboarding/build_agent_env/openrouter_provider/assets/file-response.schema.json; LangGraph agent.toml facts use agentbench/onboarding/build_agent_env/frameworks/langgraph/assets/manifest/analysis.schema.json. Planning and review have their own schemas. For example, status must be complete, needs_input or unsupported, and a file response must include path. Current LangGraph adapter.config and adapter.graph_id allow null for a native factory binding; #112's older null-field failure is not the current contract. Do not invent a graph descriptor to satisfy that historical example.

3. Supply genuine missing deployment information with --answers answers.txt. A schema or JSON decode failure is not itself a needs_input request. For provider incompatibility, choose a model that supports strict structured output using --build-model MODEL, then repeat the add command for the same source. Reusable files are preserved; a model change invalidates planning/review caches and can trigger additional paid requests. Editing a saved response-N.json does not feed a correction into the next build.

4. Do not increase retry budgets without identifying a change that could resolve the failure. The packaged repair_attempts = 1 permits one additional correction per planning stage or file, shared across model-content JSON decoding, schema checks, file validation and review. retries handles transient transport/HTTP failures separately. To limit correction calls while investigating, create build-settings.toml containing:

   [build]
   repair_attempts = 0

   Then run:

   agentbench agent add https://github.com/owner/repository -b --sdk kuma --build-settings build-settings.toml

   This disables correction attempts, not initial generation, reviews, source follow-ups or transport retries. It is a cost-control option, not a fix.

When reporting a failure, include the checkout commit, generation model, stage, settings and a sanitized structural description such as $.status: invalid enum or $.path: missing required property. Inspect source and model responses locally; exclude credentials and confidential generated content from shared diagnostics.

Interpret results on two axes

Execution	Judge	Meaning
Completed and host accepted	pass	Met this Case's criteria.
Completed and host accepted	issue	Behavioral finding; read the issue and steps.
Completed and host accepted	insufficient_evidence	Required behavior could not be established; not a proven defect by itself.
Blocked / host rejected	May retain a report	Execution/evidence acceptance failed; receiving a report does not make it accepted.
Running / retry wait	Pending	Keep partial results and attempt history.

BenchmarkResult.passed requires report status pass; aggregate FAILED therefore includes completed issue/insufficient-evidence Cases. evaluate/run can exit nonzero for a delivered non-pass verdict. Certification checks completeness and can promote an Agent with findings. Report both execution state and Judge verdict.

A real tool call, a simulated example and “I uploaded the file” are different evidence. Check actual traffic before claiming an upload or state change. For a partial trace, inspect its reason: filtering attributes, missing spans and failed export are not equivalent.

Find the supporting artifacts

Use printed paths. For managed KUMA Suites:

• results/suites/<suite-id>/: plan, immutable Cases and events.json.
• results/observe/<artifact-run-id>/run.json: execution metadata/failure status.
• network.jsonl: recorded model and tool traffic for that attempt.
• evaluation/case.json: selected Case. evaluation/inputs/<step>/: input, result, submitted output, evidence and capture/OTel status when those stages completed.
• evaluation/judge/report.json: Judge result when available.

Use the Case/attempt's artifact ID, not just the Agent name. Failure before a stage starts may leave its files absent. observe --show RUN_DIRECTORY reviews native observation artifacts offline; view opens a result JSON using the built web UI.

Runs without model calls

An Agent may return a cached answer, reject an input, use only tools, or perform deterministic work without calling a model. Zero intercepted model calls does not reject the run; the Judge evaluates the actual output and available evidence. Host trace validation still checks observed calls for terminal outcomes, capture errors, truncation and persistence failures. Zero calls alone does not prove that all possible model traffic was observed.

The former [llm_interception].required flag is no longer used. Remove it from Agent manifests; older manifests containing either value are still accepted, but the flag neither requires a model call nor disables trace validation. A tool route's separate required field still controls required network operations.

Share a report

Export current report downloads JSON containing all current Cases and attempt histories, excluding control capabilities. It does not bundle referenced traces. Review prompts, outputs and tool data before sharing; removing control tokens is not a general privacy guarantee.

For full reproduction preserve Suite and referenced attempt directories, plus source/config revisions. Saved paths may be absolute; there is no guaranteed portable import/archive command. web/dist/index.html depends on JS/CSS and local APIs; it is not a standalone report. A separately created HTML is standalone only if its required data/assets are embedded; check that particular file.

Resume, retry, reuse and clean

• resume SUITE: continue eligible unfinished slots with saved Cases/request state.
• retry SUITE --agent ID --case N: target an unfinished Case; N starts at 1.
• reuse SUITE: new linked Suite using saved Cases and current code. Changing a Profile does not change saved Cases; use fresh generation to test the new Profile.
• Completed findings are retained, not automatically rerun until they pass.

Start with agentbench clean --dry-run. Saved Suites and referenced artifacts are protected; unreferenced top-level history moves to cache/history-trash/<batch>/. Stop runs/viewers before confirming. Agent source, .env, registry, images and custom output paths are untouched. To restore, stop runs and move archived files back without overwriting newer results. This is history archiving, not a universal cache reset.

Generation, native aborts and dependency waits

dictionary changed size during iteration in TraceCallback.on_chain_end can come from a parallel graph extending shared state while the observer serializes it. Current observation code snapshots dictionary entries before recursively converting values. Run with the current ABB container build; this historical observer failure is not evidence of an Agent defect.

Agent response exceeds transport byte limit concerns the whole per-Input response directory, including framework traces and OTel payloads. It does not refer only to the final answer or to an API token quota. The default is 1 GiB; set ABB_AGENT_RESPONSE_MAX_BYTES to a positive byte count in the host environment or .env if a different budget is needed. ABB_AGENT_RESPONSE_MAX_FILES defaults to 20,000. Effective limits are saved in request/evaluation.json. Copies remain streamed, bounded and checked for links/special files. An over-limit response fails explicitly; partial copies must not be treated as complete evidence.

Case generation makes at most five total attempts per rejected candidate slot. Successfully saved Cases keep their original indices. Each attempt is recorded in case-collection.json; after the fifth failure the remaining slots for that Agent are left unattempted and its generation container is closed. Other Agents continue. Invalid credentials and ambiguous remote acceptance do not trigger five blind requests: inspect the saved SDK request identity before attempting recovery.

An ACP peer returning stopReason=cancelled is an Agent abort, distinct from a host cancellation request. ACP closes failed sessions, so ABB stops delivering later Inputs to them. The original Case remains intact; termination.json and manifest.json name the committed prefix and unexecuted tail. Judge receives the original committed evidence. A missing tool completion at the prompt boundary is recorded as not_observed, never as a successful tool result. Receiving a Judge report does not turn a native failure into a passing execution.

Recognized native dependency errors pause subsequent Case dispatch for the affected Agent. The coordinator releases execution slots, tries other Agents, and returns the waiting Agent to the ready queue after Retry-After or bounded backoff. If the exception names a dependency host, other unfinished Agents declaring that host share the cooldown; this is conservative host grouping, not per-credential rate limiting. Cooldown timestamps and budgets survive Suite resume. Existing in-flight Cases finish normally. A generic step-budget timeout alone does not prove an upstream outage.

Quota exhaustion or invalid credentials block dependent pending work until an explicit recovery after configuration is repaired. Automatic cooldown is bounded by the Suite retry policy; waits over one hour require explicit recovery. Completed reports are retained. Failed Cases are replayed only when their existing recovery contract explicitly permits isolated replay. This mechanism schedules whole Cases; it does not checkpoint arbitrary Agent memory or resume a failed turn in place. LangGraph's current Case retains its existing continue-on-failure policy.

Docker address-pool exhaustion before container startup is separately classified. Generation preparation waits and retries up to five total attempts; execution startup uses the normal bounded Case retry budget because no Agent has run yet. Only this attempt's owned resources are cleaned up. ABB does not prune unrelated networks or change Docker's global address pools. Build downloads, unknown Docker client interruptions and missing API keys require their actual cause to be fixed. The container memory policy is unchanged.
