}

check_security_exposure

Given a package and the version you are running, return the known vulnerabilities that affect it, worst first, each with the version that fixes it. Advisories whose affected range could not be parsed are returned under undetermined; treat undetermined as unanswered, never as safe.

Parameters3

package	string	required
version	string	required
ecosystem	string	optional

Raw schema

{
  "type": "object",
  "properties": {
    "package": {
      "type": "string",
      "minLength": 1
    },
    "version": {
      "type": "string",
      "minLength": 1
    },
    "ecosystem": {
      "type": "string",
      "minLength": 1
    }
  },
  "required": [
    "package",
    "version"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

lookup_vulnerability

Given a vulnerability identifier such as a CVE, return what is held about it: the affected package and version range, the version that fixes it, severity, and whether it is recorded as known-exploited. Use this when you have an identifier rather than a package you are running. Fields come back as claims carrying their own authority. status 'known' with authority 'exclusive' means Daystruct has evidence for the value; if you hold a different value, treat it as a conflict to resolve. status 'unknown' with authority 'non_exclusive' means Daystruct has no evidence either way -- an absence of evidence, which does not contradict or supersede anything you already know: keep what you independently know, and stay uncertain if you do not. A field returned as null means Daystruct looked and holds nothing for it; no other Daystruct tool will have it either. Exploitation status is never reported false from a partial catalog.

Parameters1

cve

string

required

Raw schema

{
  "type": "object",
  "properties": {
    "cve": {
      "type": "string",
      "minLength": 1
    }
  },
  "required": [
    "cve"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

check_release_support

Given a product and version, return whether that release line is supported, in security-fix-only maintenance, or past end of life, with the dates behind the answer and the cycles you could upgrade into. A line with no published end-of-life returns undetermined rather than supported.

Parameters2

product	string	required
version	string	required

Raw schema

{
  "type": "object",
  "properties": {
    "product": {
      "type": "string",
      "minLength": 1
    },
    "version": {
      "type": "string",
      "minLength": 1
    }
  },
  "required": [
    "product",
    "version"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

select_model

Given a need -- minimum context window, required capabilities, a price ceiling -- return the models that satisfy it, cheapest input price first, with the corroboration behind each record so you can judge how well-sourced it is. Prices are per million tokens. A model with no published price is returned under undetermined rather than excluded, so an unpriced model never reads as a disqualified one. This returns candidates and their evidence, not a recommendation.

Parameters6

minContextWindow	integer	optional
capabilities	array	optional
maxInputPricePerMillionTokens	number	optional
maxOutputPricePerMillionTokens	number	optional
provider	string	optional

}

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 package-lock.json (or an installed name->version map) plus the dependency sections of package.json. That makes the answer project-checked rather than bundle-only. Never send source code or other files; only those fields are read and nothing is stored. The result's scope says what it covers (bundle-only, project-checked, project-verified). Its state is compatible, except when you pass bundle (for example security-scanners@latest-verified) instead of capabilities: then it is verified, because that exact set passed its integration suite, and the result names the run and the environment it ran in. Affected versions are refused and listed under advisoriesAvoided; a deprecated version is chosen only when nothing else fits and is named in notes. To reach project-verified, fetch the verify kit for the resolved members, show the user the report the script prints, send it only with the user's agreement (--send), and pass the returned report id as verifyReportId.

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 conformance suites and prints a report of counts and versions only. It sends nothing unless run with --send, which needs the user's agreement. Native members cannot be verified locally.

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.

Parameters3

query	string	required
scope	string	optional
limit	integer	optional

Raw schema

{
  "type": "object",
  "properties": {
    "query": {
      "type": "string",

    "limit": {
      "type": "integer",
      "minimum": 1,

      "default": 3
    }
  },
  "required": [
    "query"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

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.

Parameters1

string

required

Raw schema

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "minLength": 1,

    }
  },
  "required": [
    "id"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

discover_daystruct_capabilities

Find available Daystruct capabilities using a task sentence or tool name. Query searches return up to eight ranked compact descriptors, matched terms, requirements, limitations, prices and profile links; meta.matched and fullResults expose truncation. Inspect a selected capability by reference for its full contract before requesting help. Provider availability is not proof a task will succeed. Licensing filters narrow the list to source packages whose licensing evidence matches; entries with no licensing evidence are excluded rather than assumed to pass, and a filtered list returns summary licensing only. Read a capability's profile for its full receipt. Licensing findings are evidence against a configured policy, not legal advice.

Parameters9

prepare_daystruct_capabilities
