scc

Eight principles, scored

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

1. P1
   Non-Interactive by Default

   61 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⧉ copy prompt

   Make scc satisfy P1 (Non-Interactive by Default) from the agent-native CLI standard. Address:
   - Flags advertise env-var bindings in --help (61 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.)

   warn
2. P2
   Structured, Parseable Output

   --output/--format flag detected but could not validate JSON via safe probes (--help/--version override output flags in most CLIs) · CLI emits structured output but exposes no `schema` subcommand or `--schema` flag at top level or nested one level deep. Agents need a runtime-discoverable schema to pin against shape changes.

   Remediation · P2⧉ copy prompt

   Make scc satisfy P2 (Structured, Parseable Output) from the agent-native CLI standard. Address:
   - Structured output support (--output/--format flag detected but could not validate JSON via safe probes (--help/--version override output flags in most CLIs))
   - Structured-output CLI exposes its schema at runtime (CLI emits structured output but exposes no `schema` subcommand or `--schema` flag at top level or nested one level deep. Agents need a runtime-discoverable schema to pin against shape changes.)
   - --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) (bad invocation exited with code 1. The 0/1/2/77/78 convention reserves code 2 for usage errors; using a different non-zero code (often 1) blurs the distinction between usage errors and general failure.)
   - Errors emit JSON envelope with `error`/`kind`/`message` under `--output json` (bad invocation under `--output json` produced no parseable JSON on stderr or stdout. JSON mode must emit a JSON error envelope, not plain text.)

   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⧉ copy prompt

   Make scc 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.)

   warn
4. P4
   Fail-Fast, Actionable Errors

   errors under `--output json` are not JSON-formatted. Consumers parsing stdout-as-JSON cannot recover the failure without a separate text-parsing path; switch the error writer to honor the active output mode.

   Remediation · P4⧉ copy prompt

   Make scc satisfy P4 (Fail-Fast, Actionable Errors) from the agent-native CLI standard. Address:
   - `--output json` produces JSON-formatted errors (errors under `--output json` are not JSON-formatted. Consumers parsing stdout-as-JSON cannot recover the failure without a separate text-parsing path; switch the error writer to honor the active output mode.)

   warn
5. P5
   Safe Retries & Mutation Boundaries

   All 2 checks pass.

   pass
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⧉ copy prompt

   Make scc 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.)
   Requirements: https://anc.dev/p6

   warn
7. P7
   Bounded, High-Signal Responses

   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⧉ copy prompt

   Make scc satisfy P7 (Bounded, High-Signal Responses) from the agent-native CLI standard. Address:
   - Help text advertises TTY-aware verbosity behavior (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.)
