minos

minos is a command for Claude Code from Generous-Corp/pulp. It costs 24 tokens per session (974 once invoked), scanned A, original, MIT.

A command-line tool that reads built binaries to find the oldest operating-system version they require. It can also compare that requirement with downstream projects built from an installed SDK.

In plain words
What is it for?
Use it to measure requirements for macOS, Linux, and Windows binaries, or to find consumers whose builds require a newer system than the SDK states.
Why use it?
It reveals compatibility requirements from the actual compiled files instead of relying only on project settings or declarations.

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.

Security

Grade A, and why

minos 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 today.

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

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Minimum-OS tooling. The "minimum OS" a build needs is the highest minimum among everything linked into it — the SDK's own libraries (Skia, Dawn, the JS engine), the C++ runtime, and the plugin's own compiled code. These commands read that floor straight from the built artifact, so it's the honest number, not a guess from a manifest.

Full explainer: docs/guides/minimum-os-support.md.

Measure one binary

Report the minimum OS a single built binary needs:

pulp minos measure <path-to-binary>

<path-to-binary> can be a .dylib / .so / .dll, a .a static archive, an executable, or a plugin bundle's inner binary (e.g. MyPlugin.vst3/Contents/MacOS/MyPlugin). Output is <kind> <floor>, e.g. macho 13.3 (macOS 13.3), elf 2.34 (glibc 2.34), pe 10.0 (Windows 10).

If $ARGUMENTS names a binary, measure it:

pulp minos measure $ARGUMENTS

Sweep every downstream consumer

Rebuild every downstream demo/example against one installed Pulp SDK and report each project's floor next to the SDK's floor — a DRIFT flag means a consumer's binaries ended up needing a higher OS than the SDK declares (usually a build host leaking a newer toolchain). Non-zero exit on any build failure or drift, so it can gate a release.

Dry-run first to see the plan (no clones, no builds):

pulp minos sweep --sdk-prefix /path/to/installed-sdk --dry-run

Then run it (optionally scope with --only, capture with --json):

pulp minos sweep --sdk-prefix /path/to/installed-sdk
pulp minos sweep --sdk-prefix /path/to/installed-sdk --only pulp-example-plugins,pulp-gpu-nam
pulp minos sweep --sdk-prefix /path/to/installed-sdk --json /tmp/sweep.json

The SDK prefix is an unpacked installed SDK (the directory containing lib/cmake/Pulp). Build a fresh one with cmake --install <build> --prefix <prefix>.

Notes:

  • The registry of what to sweep is planning/sdk-consumers/consumers.yaml (private submodule); per-repo build knobs are in tools/scripts/sdk_consumer_sweep_recipes.yaml. README/PKG-only release mirrors are skipped automatically.
  • pulp minos sweep needs PyYAML: python3 -m pip install pyyaml.
  • The sweep clones and builds many repositories, so it's a CLI-only command (not exposed over MCP). The pulp minos measure op is available over MCP as pulp_minos.

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.

minos is a command published in the GitHub repository Generous-Corp/pulp (16 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 974 once invoked, about $0.0001 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 2026-09-04.
