## Title

    KFA Benchmark Commons — Workbench 01: terminal field guide

## Body

    # KFA Benchmark Commons — terminal field guide
    
    Workbench 01 family research stage. Each included finding passed separate Claude analysis, adversarial review and source verification; these roles share one operator and do not constitute independent reproduction. Original summaries only; benchmark-answer-free intent. No official benchmark endorsement or measured performance improvement is claimed. Sources were bounded excerpts, not full deep reads.
    
    ## WHAT THIS TASK FAMILY TESTS
    
    - all-fail task interpretation
    - Harbor-run agent timeouts
    - terminal command execution
    - agent and model comparison
    - interaction budget and effort
    - environment reproducibility
    
    ## COMMON FAILURE MODES
    
    - Unresolved records misread as genuine hardness (wb01-terminal-a060036c373146c9bd)
    - A single-pass judge label could be wrong (wb01-terminal-a060036c373146c9bd)
    - Unbounded stalled runs when enforcement is off (wb01-terminal-e8de143f2cc8090a40)
    - Ambiguity over which timeout is active (wb01-terminal-e8de143f2cc8090a40)
    - Missing or off-PATH executables (wb01-terminal-98f1a15509741d0db4)
    - Failures while running installed executables (wb01-terminal-98f1a15509741d0db4)
    - Pre-checks could add commands without help when no substitute exists (wb01-terminal-98f1a15509741d0db4)
    - Package installs may be blocked or add external dependencies (wb01-terminal-98f1a15509741d0db4)
    - Scaffold-driven gains attributed to model capability, or the reverse (wb01-terminal-68afc309b592c90884)
    - Cutting turns prematurely could hurt tasks needing long exploration (untested) (wb01-terminal-7dfd67eabc7f7d7283)
    - Result drift from changed external resources (wb01-terminal-cf50a85dbe9c05f58a)
    - Differences in effective task environments from machine resources and runtime enforcement (wb01-terminal-cf50a85dbe9c05f58a)
    
    ## ENVIRONMENT / EVALUATOR TRAPS
    
    - Diagnose the layer behind an all-fail result before attributing it to capability: The audit reports that an all-fail score could reflect capability limits, a defective authored reference route, unavailable infrastructure, exploitable checking, or insufficient evidence of solvability, and that only part of the all-fail set meets its narrow certified-unsolved criterion. (finding wb01-terminal-a060036c373146c9bd; MODERATE; transfer LOW).
    - Heuristic Harbor deadlines are log-only unless enforcement is enabled: In the tt-inference-server agentic workflow, the Harbor progress watchdog only logs wave and stall deadlines by default, enforces them only when HARBOR_ENFORCE_AGENT_DEADLINE=true, and HARBOR_TIMEOUT_SEC is an unconditional wall-clock limit that applies when heuristic deadlines are disabled; on timeout the partial result is kept and exit code 124 is returned. (finding wb01-terminal-e8de143f2cc8090a40; MODERATE; transfer LOW).
    - Scaffold and model are confounded in leaderboard comparisons: The paper states that agent and model performance are hard to decouple because many scaffolds are engineered around the tendencies of particular models. (finding wb01-terminal-68afc309b592c90884; MODERATE; transfer MEDIUM).
    - Internet access introduces external drift: Internet access introduces external dependencies because agents may call APIs or download packages, and even stable resources can change over time. (finding wb01-terminal-cf50a85dbe9c05f58a; LIMITED; transfer MEDIUM).
    
    ## PROMISING STRATEGIES
    
    No supported finding was accepted from the supplied excerpts.
    
    ## NOT-PROMISING STRATEGIES
    
    - Command failures from executables that are missing or not on PATH: In a sample of 3,800 command failures categorized by an LLM judge, calls to executables not installed or not in PATH were the most frequent failure type at 24.1%, followed by failures when running executables at 9.6%. (finding wb01-terminal-98f1a15509741d0db4; MODERATE; transfer MEDIUM).
    
    ## RECOVERY PLAYBOOK
    
    - INFERENCE: Evaluators and maintainers should separate agent error from environment, infrastructure or checker faults using logs and controls before concluding a task is beyond capability. Unresolved cases should stay recorded as unresolved. (wb01-terminal-a060036c373146c9bd)
    - INFERENCE: When running Harbor-based terminal evals through this workflow, set the enforcement flag and wall-clock limit explicitly, record them, and treat exit code 124 as an incomplete run. (wb01-terminal-e8de143f2cc8090a40)
    - INFERENCE: Before relying on a tool, check that it exists and is on PATH (for example with command -v). If absent, use an installed alternative or install it where task rules allow. (wb01-terminal-98f1a15509741d0db4)
    - INFERENCE: When comparing strategies or models, hold the scaffold fixed or report scaffold and model together. Do not attribute a gain to the model or the strategy alone. (wb01-terminal-68afc309b592c90884)
    - INFERENCE: Do not count on extra turns to reach success. When repeated steps show no progress, stop and re-plan. (wb01-terminal-7dfd67eabc7f7d7283)
    - INFERENCE: Record package versions and downloaded resources during a run so results can be re-examined if external resources change. (wb01-terminal-cf50a85dbe9c05f58a)
    
    ## COST / LATENCY TRADEOFFS
    
    - Diagnose the layer behind an all-fail result before attributing it to capability: cost UNKNOWN; latency UNKNOWN.
    - Heuristic Harbor deadlines are log-only unless enforcement is enabled: cost UNKNOWN; latency UNKNOWN.
    - Command failures from executables that are missing or not on PATH: cost UNKNOWN; latency UNKNOWN.
    - Scaffold and model are confounded in leaderboard comparisons: cost UNKNOWN; latency UNKNOWN.
    - Using more turns as a proxy for effort or quality: cost UNKNOWN; latency UNKNOWN.

    ## WHAT IS BENCHMARK-SPECIFIC
    
    - Terminal-Bench 3 / Frontier-Bench 0.1 frozen production corpus; arXiv:2609.26826v1 (analyst summary of sections 2, 3, 6); applicability: Interpreting all-fail results on the frozen Terminal-Bench 3 / Frontier-Bench 0.1 corpus (wb01-terminal-a060036c373146c9bd).
    - Terminal-Bench version unspecified in selected documentation; aliases tb2.0 and tb2.1 are named; git:75000a69669cb116d9b4dd000594767a697ff2ab; applicability: Harbor runs launched via this repository's agentic workflow (wb01-terminal-e8de143f2cc8090a40).
    - arXiv:2601.11868v1 (section 4.5); applicability: Terminal-Bench 2.0 command-level failures as sampled across tasks and models (wb01-terminal-98f1a15509741d0db4).
    - arXiv:2601.11868v1 (section 3); applicability: Interpreting Terminal-Bench 2.0 results across agents and models (wb01-terminal-68afc309b592c90884).
    - arXiv:2601.11868v1 (section 4.1); applicability: Cross-model comparison of average turns in Terminal-Bench 2.0 runs (wb01-terminal-7dfd67eabc7f7d7283).
    - arXiv:2601.11868v1 (section 5); applicability: Reruns of tasks permitting network access (wb01-terminal-cf50a85dbe9c05f58a).
    
    ## WHAT MAY TRANSFER TO REAL AGENTS
    
    - Diagnose the layer behind an all-fail result before attributing it to capability: LOW; limits: The audit concerns this corpus, not Terminal-Bench 2.0; counts and rates should not be transferred; The study is retrospective and some labels use a single model-judge pass; The certified-unsolved criterion does not establish intrinsic difficulty or complete verification; Task rejections can involve several problems although one primary reason is assigned; The stated recommendation targets maintainers; run-time use by an agent is INFERENCE.
    - Heuristic Harbor deadlines are log-only unless enforcement is enabled: LOW; limits: Workflow documentation only; no measured effect on scores; Defaults may differ in other deployments; One deployment; independence not established.
    - Command failures from executables that are missing or not on PATH: MEDIUM; limits: The LLM judge (GPT-5) agreed with only 50 annotations from one author at 82.0%, so labeling noise is non-trivial; These are command-failure shares, not task-failure causes; The Appendix E.2 taxonomy was not supplied; Some missing-tool errors may be harmless probes.
    - Scaffold and model are confounded in leaderboard comparisons: MEDIUM; limits: No measured magnitude of the coupling is given; Vendor CLIs ran only with their own vendor's models, so the design is not fully crossed; No per-agent or per-model scores were supplied.
    - Using more turns as a proxy for effort or quality: LOW; limits: Aggregate correlation, not interventional; Agent and model are confounded, as the paper itself notes; Figure 35 was not supplied; Unknown whether the result holds within one model or task.
    - Internet access introduces external drift: MEDIUM; limits: Stated as a limitation; no measured drift rate supplied; Distinct from answer-access risk.

The paper describes missing or off-PATH executables as the largest reported category; it also reports LLM-judge calibration agreement of 82.0% on 50 annotations from one author.\n\nLimitation: These are shares of command failures, not task failures or proof that a preflight check improves success. The earlier finding's mention of an agreeing analyst summary was not separate external evidence and should be disregarded. Checking for an executable before relying on it remains an untested inference. No independent reproduction is claimed.\n\nOpen question: Across current terminal-agent setups, how often does a low-cost availability check prevent a consequential failure rather than add a redundant probe?",
