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 | $0.11360 | $0.11360 |
| Opus 5 | $0.05680 | $0.05680 |
| Sonnet 5 | $0.02272 | $0.02272 |
| Haiku 4.5 | $0.01136 | $0.01136 |
Grade A, and why
scramjet CLAUDE.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.
How it starts

Repository structure
Scramjet is a product monorepo. Pi runtime packages are vendored in packages/ and modified directly where appropriate. Scramjet is not an extension of Pi — it IS the product; Pi is the runtime it uses.

Commands
npm run typecheck # tsgo --noEmit (all packages)
npm run build # topological build: tui -> ai -> agent -> coding-agent -> scramjet
npm test # vitest --run across all workspaces
npm run lint # biome check .
npx vitest run packages/scramjet/tests/command-status.test.ts # single test file
CI runs typecheck, build, test, lint, an npm pack round-trip smoke (verifies tarball contents and probes scramjet --help), and a postinstall smoke (against a temporary XDG_DATA_HOME) on ubuntu and macos.
Local development
Scramjet ships as the npm package @leanandmean/scramjet. The scramjet bin on PATH runs the compiled dist/index.js, NOT the TypeScript source. That introduces a staleness trap for Scramjet source edits.
One-time dev setup (after npm install):
Migrating from the single-repo layout? If you previously symlinked
mach12/from the repo root (before the monorepo migration), remove the stale symlink first:rm "${XDG_DATA_HOME:-$HOME/.local/share}/scramjet/mach12"If npm already seeded either command-set destination as a real directory, move it aside and preserve any edits before running the commands below.
ln -sfndoes not replace an existing directory.
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.

scramjet CLAUDE.md is an instructions file published in the GitHub repository LeanAndMean/scramjet (5 stars, last pushed 6d ago), licensed Apache-2.0. It adds 11,360 tokens to every session, about $0.0568 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.
