• harness::spawnharness1.8.55schema

  Spawn a sub-agent in a child session (never a trigger target) and return { child_session_id, child_turn_id } immediately; the child's outcome reaches you only through whatever destination its task names. Check `harness::status` for child health; children are leaves unless options.orchestrator is true.

  • agentstring

    Directory agent profile id (`directory::agents::*`) supplying the child's prompt, skills, model, and display; refused with `options.system_prompt`. Omitted, an in-turn spawn continues the parent turn's profile (name `options.system_prompt` for a child that needs a different identity).

        The context carries a conversation summary: compacted on this step, or anchored on an earlier compaction entry (a previous step, the console's `/compact`). The summary's tokens count in `system_prompt`.

        Output allocation `usable` was derived against.

        Which estimator produced the numbers (`heuristic` until the context-manager resolves a real tokenizer). Absent when the context-manager predates the breakdown response.

          `usage.cache_read` of the rewriting request: what the provider still reused.

        • call_idstring
        • causestring

          What rewrote the row, as far as the harness can tell: `prune` (context-manager pruned or reduced function results to fit the budget that step) or `system_prompt` (row 0: a compaction summary or a prompt change).

        • indexinteger· uint64min 0

          First row (0 = system prompt, then one per message) that differs from the session's previous request. Absent when only the provider's wire mapping changed.

      • prompt_surface_digeststring

        Identity of the shared prompt prefix this generation went out with (`sha256:` of the stable section) — present only when the request carried `system_sections`. A local identity, never a provider hit; `usage.cache_read` is the reuse signal.

      • providerstring
      • session_cost_usdnumber· double

        Running cost of the whole session in USD, accumulated across every generation step. `usage.cost_usd` is one step's bill — on providers with steep cache discounts the per-step number swings two orders of magnitude, so a chip showing it alone reads as a bouncing total.

• kanban::ticket::updatekanban0.1.23schema

  Update a ticket field (title, description, status, priority, assignee, labels, parent, project, release) and return the ticket (compact returns only its compact row). To change labels pass add_labels / remove_labels (they edit the current labels, so concurrent edits do not overwrite each other); labels replaces the whole set. parent makes the ticket a subtask (one level: the parent must be live and not a subtask, a ticket with subtasks cannot become one) and null detaches it; the activity is recorded on both tickets. project and release take an id or a name; null clears. A patch that changes nothing records and fires nothing.

  Run a command in the foreground and return its full output. Put the program in `command` (string) and arguments in `args` (string[]), never argv in `command`. Host-only cwd/env/stdin reject S210 on a sandbox target. Errors return { code, message }; common: S216 host exec error, S300 VM boot failed, S200 in-VM failure.

  request

    Arguments, in order (all strings). Omit/null to tokenize `command` shell-words style; pass an array (even empty) to use it verbatim.

  Show a directory tree, bounded by max_depth, per_folder_limit and a node budget. Nodes carry only name (child path = parent path + '/' + name); over-limit folders are truncated stubs to paginate with coder::list-folder. Paths: relative to the primary root or absolute inside an allowed root (see coder::info).

  request

  • include_hiddenboolean

    List dot-prefixed entries; false omits them at every level (they then don't count toward per_folder_limit). The requested root is exempt.

  • max_depthinteger· uint32min 0

    Maximum depth to descend; the root node is depth 0.

  • pathstring

    Base folder for the snapshot (default `.`).

  • per_folder_limitinteger· uint32min 0

    Maximum children listed per folder. When more exist, the folder is flagged `truncated` and callers should switch to `coder::list-folder`.

  • use_default_excludesboolean

    Prune directories matching default_exclude_globs (see coder::info) into childless `truncated` stubs; false lists everything.

  response

  • pathstring*required

    Canonical absolute path of the requested folder (resolved through the jail). Nodes carry only `name`, and the root node's path IS this `path` — do not join the root's `name` onto it; derive children by joining from here: child path = parent path + "/" + name. Operations on derived paths re-validate through the jail.

• directory::agents::getiii-directory1.2.40schema

  Fetch one agent profile by id: the system prompt resolved through its `extends` chain, display fields, preloaded `skills` (skill ids whose bodies the harness pre-loads into the session prompt) plus `unknown_skills`, preloaded `functions` (engine function ids the harness pre-loads into the session prompt) plus `unknown_functions`, model, reasoning_effort, `skills_index` (false = sessions start without the skills index), and `inheritance_error` when the chain does not resolve. Pass raw: true for the exact on-disk file to edit with directory::agents::update.

  request

    When true, also return the exact on-disk file (frontmatter included) as `raw`, ready for directory::agents::update.

    Bundled with the worker, no file behind it (see `list`).

  • colorstring

    Harness subagent color token (closed set, validated at write time); `null` = neutral.

  • descriptionstring*required
  • extendsstring

    Parent profile id (`extends:`), as declared; `null` = none.

  • functionsstring[]*required

    Preloaded functions, resolved through `extends` (the nearest profile with a non-empty list): engine function ids whose contracts the harness pre-loads into the system prompt of every session running as this profile, so the model calls them without discovery or a contract lookup. Empty = none.

  • hiddenboolean*required

    Hidden from the chat's new-session gallery (still selectable by id).

  • iconstring

    Harness subagent icon token (closed set, validated at write time); `null` = caller picks.

  • idstring*required
  • inheritance_errorstring

    Set when the `extends` chain does not resolve (unknown parent, loop, deeper than 8): `system_prompt` and the inherited fields then come from this file alone, `raw` still round-trips so the chain can be fixed, and the harness refuses to run the profile meanwhile.

  • logostring

    Provider-native reasoning effort paired with `model`, resolved through `extends`; `null` = the model/provider default. Served verbatim and validated at use time.

  • skillsstring[]*required

    Preloaded skills, resolved through `extends` (the union of the chain's lists, root first): skill ids whose bodies the harness pre-loads into the system prompt of every session running as this profile. Empty = none. Never a filter on the skills index.

  • skills_indexboolean

    `false` = sessions running as this profile start without the names-only skills index (`<available_skills>`), resolved through `extends`; omitted when no profile in the chain sets it (on).

      Owning worker when `kind` is `worker`.

  • system_promptstring*required

    The RESOLVED identity: every ancestor's body root-first, then this file's body, frontmatter stripped, joined by a blank line; blank bodies are skipped, so a profile with no prompt of its own serves its parent chain unchanged and a prompt-less profile without `extends` serves `""`. A profile that has a body and no `extends` serves that body verbatim.

  • unknown_functionsstring[]*required

    `functions` entries the engine does not currently know (not registered right now, or a typo). Warnings — the profile still loads and the harness skips them; an empty list also results when the engine could not be asked.
