2/8principles met

Eight principles, scored

Behavioral and source checks. Every non-pass row carries a copy-paste remediation prompt.

  1. P1
    Non-Interactive by Default

    44 flag(s) found in --help but no `[env: NAME]` bindings advertised · no default-value annotations found in --help. SHOULD-tier — agents reading help text need to see what value a flag falls back to when omitted (`[default: <value>]` per clap convention).

    Remediation · P1
    Make cursor satisfy P1 (Non-Interactive by Default) from the agent-native CLI standard. Address:
    - Flags advertise env-var bindings in --help (44 flag(s) found in --help but no `[env: NAME]` bindings advertised)
    - `--help` advertises default values for flags (no default-value annotations found in --help. SHOULD-tier — agents reading help text need to see what value a flag falls back to when omitted (`[default: <value>]` per clap convention).)
    - Rich-TUI affordance for TTY contexts (no rich-TUI affordance detected (no `--tui`/`--interactive`/`--ui` flag, no spinner/progress/tui mention in --help). MAY-tier — rich TUI in TTY contexts is a nice-to-have, not required.)
    Requirements: https://anc.dev/p1
    warn
  2. P2
    Structured, Parseable Output

    no --json or --jsonl short alias found. Agents and pipelines benefit from short forms alongside the canonical `--output` enum. · no `--raw` flag advertised. MAY-tier — useful for pipelines that want to strip formatting before piping to other tools.

    Remediation · P2
    Make cursor satisfy P2 (Structured, Parseable Output) from the agent-native CLI standard. Address:
    - --json / --jsonl short aliases for --output (no --json or --jsonl short alias found. Agents and pipelines benefit from short forms alongside the canonical `--output` enum.)
    - `--raw` flag for pipe-safe unformatted output (no `--raw` flag advertised. MAY-tier — useful for pipelines that want to strip formatting before piping to other tools.)
    - Bad invocation exits with structured usage-error code (2) (binary silently accepted invalid flag (exit 0). Bad invocation must signal usage error via a non-zero exit code.)
    Requirements: https://anc.dev/p2
    fail
  3. P3
    Progressive Help Discovery

    no `examples` subcommand or `--examples` flag found. MAY-tier — a curated usage block keeps agents from hunting through long help text. · `-h` and `--help` produce byte-identical output. SHOULD-tier — clap renders the short summary on `-h` and the full description on `--help` when `long_about` is set; collapsing them gives agents no concise list-level grep target.

    Remediation · P3
    Make cursor satisfy P3 (Progressive Help Discovery) from the agent-native CLI standard. Address:
    - `examples` subcommand or `--examples` flag for curated usage patterns (no `examples` subcommand or `--examples` flag found. MAY-tier — a curated usage block keeps agents from hunting through long help text.)
    - Short `-h` summary differs from `--help` long form (`-h` and `--help` produce byte-identical output. SHOULD-tier — clap renders the short summary on `-h` and the full description on `--help` when `long_about` is set; collapsing them gives agents no concise list-level grep target.)
    - Help text pairs human and `--output json` example invocations (no paired text + `--output json` example found within 5 lines in top-level or any subcommand `--help`. Pairing keeps agents from reverse-engineering the JSON invocation from the text one.)
    Requirements: https://anc.dev/p3
    warn
  4. P4
    Fail-Fast, Actionable Errors

    binary silently accepted invalid flag (exit 0) · stderr lacks a hint phrase. Looked for one of: try , use , expected , did you mean, see , run , for more, tip:, help:, hint:, suggestion:, available . Error messages must name what to do next, not just the symptom.

    Remediation · P4
    Make cursor satisfy P4 (Fail-Fast, Actionable Errors) from the agent-native CLI standard. Address:
    - Rejects invalid arguments (binary silently accepted invalid flag (exit 0))
    - Error messages include a hint or remediation phrase (stderr lacks a hint phrase. Looked for one of: try , use , expected , did you mean, see , run , for more, tip:, help:, hint:, suggestion:, available . Error messages must name what to do next, not just the symptom.)
    Requirements: https://anc.dev/p4
    fail
  5. P5pass
  6. P6
    Composable, Predictable Command Structure

    pager referenced in --help but no --no-pager escape hatch advertised · no `--color` flag advertised. MAY-tier — `auto|always|never` lets agents and pipelines override the TTY-based default.

    Remediation · P6
    Make cursor satisfy P6 (Composable, Predictable Command Structure) from the agent-native CLI standard. Address:
    - Pager-using CLI ships --no-pager escape hatch (pager referenced in --help but no --no-pager escape hatch advertised)
    - `--color` flag for explicit color control (no `--color` flag advertised. MAY-tier — `auto|always|never` lets agents and pipelines override the TTY-based default.)
    - Operations are subcommands, not verb-shaped flags (top-level verb-shaped flag(s) found: --remove. Operations belong under the `Commands:` block (`tool search "q"`), not on the flag namespace where they fight the `--help` filtering agents rely on.)
    Requirements: https://anc.dev/p6
    warn
  7. P7
    Bounded, High-Signal Responses

    no --quiet/-q flag detected in --help output · no TTY-aware language found in `--help`. MAY-tier — automatic verbosity reduction when stdout is piped or redirected lets agents skip the explicit `--quiet` flag. Behavioral probes cannot simulate a real TTY without a pty crate, so this audit relies on documented intent.

    Remediation · P7
    Make cursor satisfy P7 (Bounded, High-Signal Responses) from the agent-native CLI standard. Address:

SKIPRead and write surfaces are both visible in subcommand listno recognizable read or write subcommand verbs; the read/write distinction is unobservable from the help surface alone.
