25 tools

• daystruct_status

  Read the public Daystruct manifest: how capabilities are discovered, checked for compatibility and delivered.

• search_entities

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Search normalized entities by databank, type, provider, or capability.

• get_entity_evidence

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Read canonical facts, aliases, history, and provenance for an entity.

• get_context_contract

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Read a databank's identity, temporal, dimension, and context-packet contract.

• answer_software_questions

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Resolve up to four package/API questions and an optional runtime compatibility check.

• check_security_exposure

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Given a package and the version you are running, return the known vulnerabilities that affect it, worst first…

• lookup_vulnerability

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Given a vulnerability identifier such as a CVE, return what is held about it: the affected package and version…

• check_release_support

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Given a product and version, return whether that release line is supported, in security-fix-only maintenance, or…

• select_model

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Given a need -- minimum context window, required capabilities, a price ceiling -- return the models that satisfy…

• read_recent_evidence_changes

  Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Read the bounded canonical change feed.

• compat_check

  Resolve Daystruct capabilities to exact versions that fit each other, or get the exact constraint that broke with suggested alternatives. Send the project manifest by default: project.runtime (the node or python version the project runs), project.platform, and the project's…

• get_compat_verify_kit

  Return the files of the local verify step for exact source members from compat_check: a script, its plan, and the interface conformance suites. Write them to a scratch directory and run `node daystruct-verify.mjs` from the user's project; it runs the members' own tests and…

• get_daystruct_validated_guidance

  Retrieve reviewed Frontier guidance scoped to an exact databank, task family and tested model. Returns only live, unexpired promotions and their evidence limits; never private test fixtures.

• list_daystruct_guidance_scopes

  Find task families and exact tested models with live Frontier guidance for a databank, before requesting that guidance.

• plan_project_development

  Get a small stage-specific capability selection and concrete next actions from a caller-approved project projection. Keep source and full snapshots local. Caller-reported outcomes are not verified execution. Does not acquire, execute, store project context or send reminders.

• get_daystruct_account

  Read the connected key's account: available and reserved credits, the key's scopes, its per-call spending limit (null means none) and where the owner adds credits. Check this before a paid call, show the user the price first, and tell them what was spent afterwards. Read-only…

• resolve_task_capabilities

  Select relevant capabilities progressively, or request full delivery. Charges the published resolve price (/api/v1/pricing) to a key with read + requests:write; data.economics reports chargedCredits and creditsRemaining. Optional maxPriceCredits caps this call. Optional task…

• create_task_session

  Start compact task context with optional capability steps and dependencies. Requires read and requests:write. No conversation or reasoning trace is stored.

• record_task_event

  Report viewed, called, succeeded, failed or skipped capability status, or task stage. Usage and outcomes remain client-reported.

• get_task_session

  Read compact task context or preview the next ready capabilities without consuming them or extending the session TTL.

• close_task_session

  Close a task with its reported outcome and compact summary.

• search_daystruct_library

  Search this account's saved or owned capabilities and bundles. Returns a small shortlist; saving does not acquire, execute or grant access to source. Inspect a selected profile before use.

• resolve_daystruct_bundle

  Read a saved, owned or public bundle with pinned source versions and current member availability. Returns a composition plan, not an execution or purchase. Each capability retains its usage terms.

• discover_daystruct_capabilities

  Browse every public Daystruct capability without an account, or search using a task sentence or tool name. Lists default to eight compact descriptors. Set limit (1-100) and offset to follow meta.nextOffset until null; view: full returns up to 100 full metadata records per page…

• prepare_daystruct_capabilities

  Group up to six discovered capability IDs into a plan with each profile and delivery instructions. Missing entries remain explicit. Does not acquire, execute, check combined compatibility or charge credits. Your agent can combine these pieces with Daystruct knowledge and verify…
