feat(policy): reasoning-effort field carried by opencode-http - #818
Conversation
…643) `effort` is a free-form string on `[adapter]` and every `[adapter.<stage>]` table, inherited like `model` (client-specific: a stage that switches client falls back to "" = provider default), round-tripped through the policy snapshot, and appended last on `SessionSpec`. Both construction sites (the engine and `resolve.run_session` via `cmd_resolve`) pass it. The opencode-http adapter stashes it once on the server session and sends it as the per-call `variant` on every `prompt_async` body — the initial prompt and every nudge — omitting the key when empty so an effort-less body is byte-identical to before. It never rides OPENCODE_CONFIG_CONTENT: the config has no top-level `variant`, and `agent.<name>.variant` is inert unless that agent also pins a model (the issue's measured negative). The tmux generic family has no channel for it and ignores it; `validate` reports `policy.effort-unsupported` as a warning (exit code unchanged) when a stage on that family sets it, silent for opencode-http and out-of-tree kinds. `config_digest` is untouched: the value never reaches argv. Closes #643

`resolved()` decided "same client" by exact string, so a base `opencode` with `[adapter.review] name = "opencode-http"` (one profile under `get_profile`) was treated as a client switch and dropped the inherited model, effort and extra_args. Compare canonical names instead. The alias table moves into the pure core as `policy.PROFILE_ALIASES`; `adapters.profile.ALIASES` re-exports it so there is one table, and a test pins that identity.

The real session sends it as the prompt_async `variant` (#643), so a preview that read the same with and without it could not confirm the per-stage configuration. Rendered under the policy key beside the model, absent when unset. Also tersen the alias-fix changelog entry.

_render_invocation chose the HTTP preview on profile.hookless. The registry decoupled that axis from the adapter kind: an opencode-http profile with a hook dialect still launches the HTTP adapter (and sends effort), and a hookless profile of another kind never does. Follow profile.adapter, as make_adapters does; both directions are pinned.

Allow an explicit empty stage effort in the settings UI
When a base OpenCode configuration sets effort but one same-client stage should use the provider default, policy requires an explicit stage effort = "" to override inheritance. This str field cannot express that through the TUI: SettingsScreen._collect() converts a blank input to None, and saving deletes the stage key, causing AdapterPolicy.resolved() to inherit the nonempty base effort instead. Add an explicit inherit/override representation (or otherwise preserve an intentional empty string) for stage effort.
Useful? React with 👍 / 👎.
There was a problem hiding this comment.
Acknowledged, but this is the pre-existing shape of every stage str field, not something effort introduces: a stage model = "" means "CLI default, beating the base" in exactly the same way (test_stage_same_client_inherits_and_overrides pins it), and SettingsScreen._collect() collapses a blank model to a delete just as it does here. effort deliberately mirrors model field-for-field (same parser, same same_client inheritance, same str kind in core.toml), so it inherits the same TUI limitation rather than adding a new one. Giving stage name / model / effort a tri-state inherit-vs-explicit-empty widget is a settings-editor design change that belongs in its own issue, applied to all three at once; the policy file expresses it today. Leaving as-is in this PR.

Since both the initial prompt and every nudge go through_prompt, the value rides every turn.

This deliberately diverges from the verdict comment on #643 ("mirror how
_config_contentcarriesmodel"). Checked against the live config schema and OpenCode'ssession/prompt.ts:Configtype has no top-levelvariant. The only config-side effort key isagent.<name>.variant, whose schema description reads "applies only when using the agent's configured model", andcreateUserMessageimplements exactly that:variant = input.variant ?? (ag.variant && same && ... ? ag.variant : undefined)wheresamerequiresag.modelto be set and equal to the session model. That is why the reporter's{"agent":{"build":{"variant":"max"}}}probe measured baseline tokens — the key is inert without an agent-level model. Carrying effort that way would also silently do nothing whenevermodelis unset and would break under a projectopencode.jsonthat setsdefault_agent.PromptInput(shared byPOST /session/{id}/messageand/prompt_async) carriesvariant: Schema.optional(Schema.String), honored first. It is the API's own per-call effort parameter.So the value is stashed once on the server session (the "set once" property holds) and emitted by the single
_promptprimitive both the initial prompt and every nudge use — a nudge that dropped back to the provider default mid-session would be silent drift. Rejected-send risk is nil on a current server (the key is schema'd) and on an older one (unknown keys are ignored). Happy to move it if you'd rather have the config path anyway.Not carried: effort on
