Server tool list (27)
Raw names from tools/list. Only developers need these.
| solve | Decompose, ground, and answer a non-trivial task. Supports saved or per-call depth, safe trace, caller tools, and lean/full output. |
| get_capabilities | List solve modes and every public capability. |
| get_settings | Read this caller's saved solve and safety settings. |
| set_settings | Save caller-scoped settings from one dict (depth, optimization, trace, relay, governance); keys and values in get_capabilities. |
| get_result_detail | Fetch the full caller-owned result behind a lean solve. |
| export_result | Export a caller-owned result in a supported format. |
| compress_context | Compress long context into a task-focused brief; use before reading any source over 8,000 characters. |
| delegation | Create, resume, or report a bounded subagent packet (action='create'|'resume'|'report'). |
| handoff | Create, safely resume, or list caller-scoped cross-session checkpoints (action='create'|'resume'|'list'). Create accepts an optional subject and source_sessions; Liminality assigns the subject number. Resume by handoff_id — 'latest' resumes the newest unfinished resumable checkpoint, or asks which one when several were created in the last 24h; detail='full' returns the complete checkpoint. |
| ask_form | Create a short form for missing user-specific facts. |
| apply_form | Apply form answers to sharpen a task. |
| report_outcome | Report verified real-world outcome evidence for a result. |
| report_feedback | Report structured feedback on a result. |
| apply_grade | Apply a grade-form answer to a result. |
| optimize | Rank bounded one-factor variants for a route against your stated objective; candidates remain unsaved. |
| algorithms | Create, validate, release and run pure algorithms over versioned datasets; runs replay byte-identical with zero model calls. action='run' is one solve; other actions are free. |
| task | Read or version the contract behind a solve (action='get'|'list'|'versions'|'new_version'|'graph'|'create'|'state'); graph also returns what is still unfinished. |
| recover | Find a workaround for a blocked obligation without changing the task: open a case, read candidates with their boundary, choose, retry, verify against the original criteria (action='open'|'candidates'|'choose'|'retry'|'verify'|'add_candidate'|'get'|'list'). |
| runs | Run lifecycle with run and attempt identity (action='start'|'status'|'list'|'cancel'|'reconcile'|'attempt'|'execute'|'outcome'|'approve'|'grants'|'revoke'): cancel persists, an unknown effect is reconciled before any retry, simulate never executes, approve grants operation_kinds for hours and returns approval_id. |
| research | Run a multi-source research pass for a question. |
| composio_connect | Create a caller-scoped connection link for a toolkit. |
| register_asset | Register a caller-owned resource for future grounding. |
| set_priorities | Save caller-scoped tasks and importance signals. |
| taxis | Return this caller's deterministic ranked priority frame. |
| catalog | Read the capability catalog: action='search' returns every saved candidate for an objective with distinctiveness deltas; action='delta' compares a named entity pair. |
| setup | Context-minimality setup with no questions (auto); or profiles, status, verify. |
| manage | Compatibility router for retained-context lifecycle actions. |
