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.
npx agentmods add instructions/markskrypka/stem/agents-mdgit clone --depth 1 https://github.com/markskrypka/stemWhat 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 | $0.00274 | $0.00274 |
| Opus 5 | $0.00137 | $0.00137 |
| Sonnet 5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
stem 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 yesterday.
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
stem.cooking
Engineering discipline for coding agents, shipped as skills. This repository builds itself under its own rules.
Always work through the stem skill: size the work, keep
docs/planning/ current, verify before done.
Commands
pnpm install— install workspace dependenciespnpm check— validate skills, versions, and the forbidden-terms guardpnpm lint— markdown lintpnpm build— build the site shell
Invariants
- No telemetry, no network calls from the plugin — ever.
- Public copy always says
stem.cooking, never the bare short name. - This repository stands alone: no references to other workflow products' branding or history, anywhere, by convention.
skills/stem/(one skill plus its references) is canonical; there is no build step for plugin content.- Version lives once in
package.json; manifests must match (scripts/check-versions.mjs). - The repository owner runs Git: never init, commit, or push without being asked.
Current state
Read docs/planning/worklog.md (newest first) and
docs/planning/active/v1-build/work.md for status and the exact next
action.
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.

stem AGENTS.md is an instructions file published in the GitHub repository markskrypka/stem (2 stars, last pushed 27d ago), licensed Apache-2.0. It adds 274 tokens to every session, about $0.0014 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.
