What is kempt-checkup?

A read-only health check for local AI coding-agent files and settings. It looks for accumulated problems such as stale instructions, unused tools, and conflicting configuration.

Use it to scan the local agent state, report a health score and problem areas, and identify the most important cleanup items.

It shows what may be making an agent slow, inconsistent, or confused without changing the files it examines.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00089	$0.00647
Opus 5	$0.00044	$0.00324
Sonnet 5	$0.00018	$0.00129
Haiku 4.5	$0.00009	$0.00065

Security

Grade A, and why

kempt-checkup 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 11d 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.

Kempt Checkup — diagnose agent debt (read-only)

You are running a read-only diagnosis of the user's local agent state with the Kempt CLI. Nothing is modified, nothing leaves the machine.

Steps

Locate the CLI. Run command -v kempt. If missing, try node <kempt-repo>/bin/kempt.mjs (ask the user where the Kempt repo is, or suggest npm install && npm link inside it). Use whichever works as $KEMPT below.
Scan. Run:
```
kempt scan --json
```
This performs the read-only scan and prints the full report as JSON.
Interpret the report for the user. From the JSON, extract:
- healthScore (0–100) and verdict
- the five dimensions (memory / tools / conflict / runtime / reclaimable), each with severity (crit/warn/good), metricValue and summary
- summary.totalFindings and summary.reclaimableBytes
- worstDimension — lead with this one.
Present a short, plain-language readout in the user's language: what is hurting the agent most, why it matters (stale memory gets re-read every session; unused skills eat context budget; conflicting instructions make behavior random), and the 2–3 highest-impact items from findings (use title + reason; findings are already path-redacted).
Offer the next step, don't take it. If anything is cleanable, tell the user a reversible cleanup is available via the kempt-clean skill or kempt clean (dry-run by default). Do not clean anything in this skill.

Rules

This skill is strictly read-only: only kempt scan, kempt report, kempt plan and kempt history may be run. Never run kempt clean --yes or kempt empty-recycle here.
Never paste raw secrets or file contents into the conversation; the report is already redacted — stick to what it provides.
If the scan fails, show the error and suggest kempt help; do not retry more than once.
Health score bands for your summary: ≥80 tidy ("kempt"), 60–79 needs a tidy-up, 40–59 noticeable debt, <40 the agent is being actively degraded.

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.

kempt-checkup is a skill published in the GitHub repository xz1220/Kempt (2 stars, last pushed 3mo ago), licensed MIT. It adds 89 tokens to every session and 647 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
