openings-mcp: Skill for Claude Code

.agents/skills/verify-companies/SKILL.md

verify-companies is a skill for Claude Code, Codex from amikai/openings-mcp. It costs 51 tokens per session (1,324 once invoked), scanned A, original, MIT.

A checker for company lists used by job-search systems, where each company entry points to an applicant-tracking-system job board. It tests whether those boards and sample job details still work.

In plain words
What is it for?
Use it to audit and prune stale boards, promote tested companies into the internal roster, and investigate errors from company searches.
Why use it?
It identifies dead, stale, or broken company entries and distinguishes an empty live board from a failed search or detail lookup.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is amikai/openings-mcp's own configuration. It tells Claude Code and Codex how to work on openings-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openings-mcp configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go run ./cmd/verify-companies [--provider ashby,greenhouse,lever,workday] \.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verify-companies scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Verify Companies

Overview

cmd/verify-companies sweeps every curated companies.yaml entry through the real internal/ats adapter path — the same code the MCP server serves — and reports each entry as OK with its total job count, or ERROR with the error message. Each successful search is followed by one Detail probe on a sampled job. Two workflows build on it: audit (find and prune stale roster entries) and promotion (move unverified/<provider>.yaml candidates into the curated roster).

The sweep

go run ./cmd/verify-companies [--provider ashby,greenhouse,lever,workday] \
    [--format text|json] [--concurrency N] [--timeout D]
  • Any Search failure is ERROR — a stale identifier's 404 and a transient timeout or 5xx look the same at the status level; the detail column tells them apart.
  • DETAIL_ERROR means the search succeeded but the Detail probe on a sampled job failed — usually a detail-template divergence in the adapter (issue #196's shape), not a stale roster entry. The fix is adapter code, not the roster.
  • zero-job in the summary is informational: board live, no current openings. Not a failure. Zero-job boards get no Detail probe.
  • Keep the default 300s --timeout: the largest full-dump boards (e.g. Palantir, Veeva on lever) take minutes to download, and 60s produced false ERRORs.
  • Recruitee is auto-capped at 2 concurrent workers inside verify-companies (even when --concurrency is higher): its public API rate-limits hard (HTTP 429) around the default pool size.
  • Exits non-zero on any ERROR or DETAIL_ERROR, so it doubles as a CI check.

Audit workflow

  1. Sweep, scoped with --provider when you already know the target; --format json when you'll process the results.
  2. Re-run the failures once before touching the roster — transient timeouts and 5xx clear on retry; stale identifiers (404, unknown board) don't. Read the detail column, don't just count statuses.
  3. For each confirmed-stale ERROR and each OK entry with 10 or fewer jobs, web-search the company's current careers page (<company> careers) — a dead or near-empty board is often a leftover after the company moved to another ATS. Then, by what the careers URL shows (adapter host shapes: careersHostPatternsByAdapter, internal/ats/registry.go):
    • Another supported adapter's host → the company migrated. Move the entry to that provider's companies.yaml, slug taken from the URL, and verify with --provider <new>.
    • Same provider, different slug → fix the slug.
    • Same provider, same slug → small company; leave it.
    • No working careers page or unsupported ATS → remove the entry. If only the display name is in doubt, move it to unverified/<provider>.yaml.
  4. go test ./... — registry tests catch roster mistakes.
  5. Commit per the roster: convention in AGENTS.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
