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 | $0.00269 | $0.00269 |
| Opus 5 | $0.00134 | $0.00134 |
| Sonnet 5 | $0.00054 | $0.00054 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
skills AGENTS.md 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 3d 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.
What it actually says
Agent guide
Keep skill docs short and effective
Skills are consumed by agents, not read as blog posts. Say what the correct behaviour is and show it — then stop. Don't pile on caveats, notes and inline comments beyond what a reader needs to act on the example.
Never edit skills/upstash/ by hand
It is generated by scripts/build.mjs from each skills/upstash-*/SKILL.md. The build strips the frontmatter and writes overview.md into the combined skill.
To change a sub-skill:
- Edit
skills/<skill-name>/SKILL.md— the source of truth. - Run
npm run buildto regenerateskills/upstash/. - Commit both the source and the regenerated output.
CI runs npm run check, which fails if the generated output is stale. check.mjs asserts that git status --porcelain is empty after rebuilding, so it only passes on a fully clean tree — commit your source edits and the regenerated output before running it, otherwise it reports them as "out of date".
The build's pre-check also refuses to run while skills/upstash/ has unstaged changes — if you edited it by mistake, git restore skills/upstash/ first.
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.

skills AGENTS.md is an instructions file published in the GitHub repository upstash/skills (23 stars, last pushed 6d ago), licensed MIT. It adds 269 tokens to every session, about $0.0013 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 2026-08-30.
