Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00082 | $0.02875 |
| Opus 5 | $0.00041 | $0.01437 |
| Sonnet 5 | $0.00016 | $0.00575 |
| Haiku 4.5 | $0.00008 | $0.00287 |
Grade A, and why
caveman-setup scanned grade A with 1 finding 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.

How it starts
The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are wiring this repository through the Caveman gateway. Caveman is a byte-preserving LLM proxy: in record mode it measures what your app sends and what it costs, and changes nothing else. Your job is a minimal, verified integration — not a refactor.
The prompt that sent you here provides four values. Refer to them as:
GATEWAY— the gateway base URL (e.g.https://gateway.caveman.soorhttp://127.0.0.1:8787)CAVE_API_KEY— the gateway auth secret (treat like any API key: env var only, never committed, never printed in full)PROVIDER_KEYS—stored(provider keys live encrypted in Caveman Cloud) orbyok(this app sends its own provider key per request)DASHBOARD— the dashboard base URL (e.g.https://app.caveman.so)
If any value is missing, stop and ask for it. Do not guess a URL or mint a key.
Rules (non-negotiable)
- Coherent integration. Wire every live LLM callsite through existing configuration and responsible seams. Touch each layer correctness requires. No drive-by refactors or formatting sweeps; add an abstraction only when it clarifies ownership or lowers lifecycle cost.
- Secrets stay in env vars.
CAVE_API_KEYgoes into the env file the repo already uses (.env,.env.local, …). If that file isn't gitignored, add it to.gitignoreand say so. Never hardcode the key in source. - Report only what you observed. The final report states the HTTP status and usage numbers from the real verification response — never assumed success. If verification fails, report the failure template instead.
- Record mode only. You are adding measurement. You do not enable any optimization, and you do not claim any savings — verified savings are $0 until an optimizer is explicitly turned on and passes its eval gate.
- Provider keys are not your business. With
PROVIDER_KEYS: storedyou never see one. Withbyok, the app's existing provider key stays exactly where it already is.
Step 1 — Find every live LLM callsite
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

caveman-setup is a skill published in the GitHub repository Youngmaidainon/Agent-Level-Up (3 stars, last pushed 11d ago), licensed MIT. It adds 82 tokens to every session and 2,875 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
