check-keywords

check-keywords is a skill for Claude Code from dcassil/resume-kit. It costs 95 tokens per session (1,136 once invoked), scanned A, original, Apache-2.0.

A keyword-coverage checker that compares a resume with a specific job description and reports matched and missing terms.

In plain words
What is it for?
Use it to measure job-keyword coverage and decide which terms may need attention.
Why use it?
It shows which words from the job posting the resume already contains, without reducing the result to a single overall score.

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

check-keywords 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Renamed: check-keywords was check-keyword-match before v1.0.0 (see RIT-A-0005).

check-keywords — resume↔job keyword coverage

Prerequisites

Run the shared Prerequisites gate first — see _shared/prerequisites.md.

  • Required inputs (BOTH):
    • a ResumeDocument JSON — the active_resume pointer in resume-kit/config.json (or an explicit resume JSON path the caller passes).
    • a JobDescription JSON — the active_job pointer in resume-kit/config.json (or an explicit job JSON path the caller passes).
  • If either is missing (no pointer, file absent, or a raw file where a canonical JSON is required): STOP. Do not guess and do not run on partial input. Tell the caller exactly which is missing and name the upstream skill:
    • Missing/unconverted resume → run parse-resume first.
    • Missing/unconverted job → run parse-job first.

Conversions are best run in subagents (large intermediate text stays out of the main context); pass the saved JSON paths back here.

Purpose

Answer one question: how much of the job's keyword set does this resume already cover, and which specific keywords are matched vs. missing? Use it to decide whether a resume needs alignment before applying, or to see exactly which job terms to address.

This is deliberately one job: keyword coverage only. It does not report a composite/overall ATS score, section completeness, or structural parse issues (that is check-structure), and it is distinct from the missing/injectable keyword breakdown of check-gaps.

How to invoke

Prefer the MCP tool in-process; use the CLI when scripting.

CLI

resume-tool match --resume <resume.json> --job <job.json> \
    [--alias-file <path>] [--output {json,text,md}] [--strict]

MCP tool: resume_check_job_match

Input fields: resume (serialized ResumeDocument), job (serialized JobDescription), alias_file, strict.

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.
