opencode CLI

Eight principles, scored

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

1. P1
   Non-Interactive by Default

   no non-interactive flag found in --help; expected one of: --no-interactive, --non-interactive, -p, --print, --no-input, --batch, --headless, -y, --yes, --assume-yes · 20 flag(s) found in --help but no `[env: NAME]` bindings advertised

   Remediation · P1⧉ copy prompt

   Make opencode satisfy P1 (Non-Interactive by Default) from the agent-native CLI standard. Address:
   - Non-interactive gate flag advertised in --help (no non-interactive flag found in --help; expected one of: --no-interactive, --non-interactive, -p, --print, --no-input, --batch, --headless, -y, --yes, --assume-yes)
   - Flags advertise env-var bindings in --help (20 flag(s) found in --help but no `[env: NAME]` bindings advertised)
   Requirements: https://anc.dev/p1

   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 opencode 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.)
   Requirements: https://anc.dev/p2

   fail
3. P3
   Progressive Help Discovery

   --help output exists but no examples section detected · no `examples` subcommand or `--examples` flag found. MAY-tier — a curated usage block keeps agents from hunting through long help text.

   Remediation · P3⧉ copy prompt

   Make opencode satisfy P3 (Progressive Help Discovery) from the agent-native CLI standard. Address:
   - Help flag produces useful output (--help output exists but no examples section detected)
   - `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.)
   - 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.)
   - Command-list entries name the command without repeating the binary name (command-list entries repeat the binary name `opencode`: `opencode completion`, `opencode acp`, `opencode mcp`, `opencode [project]`, `opencode attach <url>` and 17 more. Drop the prefix so a reader or agent scanning the block gets the command token directly instead of reconstructing it from a repeated binary name.)

   Fail-Fast, Actionable Errors

   All 3 checks pass.

   Safe Retries & Mutation Boundaries

   All 2 checks pass.

6. P6
   Composable, Predictable Command Structure

   pager referenced in --help but no --no-pager escape hatch advertised · 4/21 subcommand(s) follow standard verb names. Non-standard: completion, acp, mcp, attach, debug, providers, agent, web, models, stats, export, import, github, pr, session, plugin, db. MAY-tier — community-standard verbs (get/list/create/update/delete) help agents predict subcommand behavior across CLIs.

   Remediation · P6⧉ copy prompt

   Make opencode 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)
   - Subcommand verbs follow community-standard names (4/21 subcommand(s) follow standard verb names. Non-standard: completion, acp, mcp, attach, debug, providers, agent, web, models, stats, export, import, github, pr, session, plugin, db. MAY-tier — community-standard verbs (get/list/create/update/delete) help agents predict subcommand behavior across CLIs.)
   - `--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 --quiet/-q flag detected in --help output · long-running subcommand present but no timeout flag advertised (looked for --timeout, --deadline, --max-time). SHOULD-tier — without a bound, agents that hit a hung operation have to enforce timeouts externally.

   Remediation · P7⧉ copy prompt

   Make opencode satisfy P7 (Bounded, High-Signal Responses) from the agent-native CLI standard. Address:
   - Quiet mode available (no --quiet/-q flag detected in --help output)
   - `--timeout` flag for long-running operations (long-running subcommand present but no timeout flag advertised (looked for --timeout, --deadline, --max-time). SHOULD-tier — without a bound, agents that hit a hung operation have to enforce timeouts externally.)
   - 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.)
