Vendor advisory detail

get_vendor_advisory
Read-onlyIdempotent

Fetch a full vendor advisory by vendor slug and advisory ID to get severity, CVE IDs, affected products, remediation, and withdrawal status.

Instructions

One vendor advisory in full, by vendor and the vendor's advisory ID (the vendor and vendor_advisory_id of a vendor advisory row): title, description, severity, cvss_v3_score, cve_ids and known_cve_ids (those with a record in EchelonGraph's CVE feed), affected_products, remediation, references, vendor_modified_at, and withdrawn_at and withdrawn_reason when the vendor withdrew it. remediations lists each remediation the vendor lists, with kind (the vendor's own category, never read from the text: vendor_fix, workaround, mitigation, no_fix_planned, none_available or other), source_category, text, url and the cve_ids and product_ids it covers; each text is the vendor's, verbatim, untested by EchelonGraph. remediation_state is parsed, none_in_source, not_parsed or withdrawn: none_in_source and not_parsed are not a finding that no fix exists. Each advisory carries vendor_published_at (the vendor's date), our_first_seen_at (when EchelonGraph first recorded it) and withdrawn (true: the vendor rescinded it). Each advisory also carries rejected_cve_ids: the CVE IDs it names whose CVE record was rejected (withdrawn) by its numbering authority, which are not active vulnerabilities. coverage.vendor_window is that vendor's window in what EchelonGraph holds: vendor, advisories, earliest_vendor_published_at, latest_vendor_published_at, held_since (where that window begins) and history_backfill (in_progress or not_started: older advisories not all held yet); null when the windows could not be read or carry none for that vendor. measured_at is our_first_seen_at. Its freshness is null: the answer carries no poll-completion time. Past 30,000 characters of JSON, the first text block holds data cut to fit, and the note says what the cut leaves out and where to read it (TEXT CUT); so is structured data (DATA CUT), unless full: true.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fullNotrue: data in the structured result is the answer whole, however long. Without it, a structured result past 30,000 characters of JSON has its data cut (DATA CUT): in an order the note states, the entries of its longest lists keep only some of their fields, and then the lists only some of their entries; data_truncated is true, and truncated gives each list cut with its total, the number returned and whether its entries are thinned. Whole data is for a program; a client that sizes structured results, as Claude Code does against MAX_MCP_OUTPUT_TOKENS, can refuse an answer past its cap.

TDQS

A3.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnly, idempotent, openWorld, non-destructive), so the bar is lower, yet the description adds real behavioral context: the 30,000-char TEXT CUT/DATA CUT truncation and the meaning of full:true, freshness being null, withdrawn/rejected semantics, and the warning that remediation_state none_in_source/not_parsed is not a finding that no fix exists. Much of the remaining text is output-field enumeration rather than behavior, keeping it from a 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

After a crisp first clause the description becomes a massive run-on enumerating nearly every output field, which is largely redundant given an output schema exists. It is neither front-loaded nor economical; sentences sprawl across dozens of comma-joined clauses.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only single-record get with a full output schema and complete annotation coverage, the description is more than sufficient on the data side and even documents truncation edge cases. What it lacks is the routing/usage context (when to prefer this over the search siblings), so it is not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description restates the truncation behavior linked to full:true, but the schema already documents full, vendor, and advisory_id in detail; the description adds little meaning beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence gives a specific verb+resource+key: 'One vendor advisory in full, by vendor and the vendor's advisory ID.' This clearly distinguishes a single-record lookup from the search/for-CVE siblings (search_vendor_advisories, vendor_advisories_for_cve). It stops short of explicitly naming those alternatives, so it does not reach 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied by the retrieval key (you must already have the vendor slug and advisory ID), and there is a fragment of guidance in the 'unless full: true' note. There is no explicit when-to-use/when-not statement nor a pointer to the search sibling for discovering IDs, so this is implied usage at best.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
