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 | $0.00036 | $0.00630 |
| Opus 5 | $0.00018 | $0.00315 |
| Sonnet 5 | $0.00007 | $0.00126 |
| Haiku 4.5 | $0.00004 | $0.00063 |
Grade A, and why
cmajor-external 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cmajor External Toolchain
Use this skill when a task involves Pulp's current Cmajor support lane.
Truthful Position
Pulp supports Cmajor as an external toolchain, not as a vendored runtime.
Supported now:
.cmajor/.cmajorpatchsource examples- patch-structure validation through
tools/scripts/cmajor_external.py doctor - generated-artifact invocation through a user-provided
cmaj - docs and workflow guidance for the MIT-safe lane
Not supported by this skill:
- shipping the Cmajor engine/JIT/runtime in Pulp core
- claiming a finished
Processoradapter for arbitrary Cmajor patches - blanket hot-reload claims
- broad multi-DSL parity claims
Core Files
docs/guides/cmajor.mdtools/scripts/cmajor_external.pydocs/contracts/pulp-dsl-v1.mdexamples/cmajor-gain/
Recommended Workflow
1. Validate the example or patch layout first
python3 tools/scripts/cmajor_external.py doctor \
--patch examples/cmajor-gain/CmajorGain.cmajorpatch
Use --require-tool when the next step truly depends on a real cmaj.
2. Keep cmaj external
Preferred resolution order:
--cmaj /path/to/cmajCMAJ_BIN=/path/to/cmajPATH
Do not turn the upstream Cmajor runtime/toolchain into a bundled dependency of Pulp unless the repo's license policy changes.
3. Generate artifacts explicitly
python3 tools/scripts/cmajor_external.py generate \
--patch examples/cmajor-gain/CmajorGain.cmajorpatch \
--target cpp \
--output /tmp/CmajorGain.cpp
Pass through target-specific args with repeated --arg flags.
4. Keep docs truthful
When editing this lane, keep these in sync:
docs/guides/cmajor.mddocs/reference/capabilities.mddocs/guides/examples.mdplanning/v3-phase14-gap-closure-status.md
What To Check
For the current Cmajor lane, verify:
- patch manifest/source layout is valid
- missing-tool diagnostics are explicit
- helper commands target the user-supplied
cmaj, not an assumed bundled tool - docs do not imply a shipped runtime or checked-in generated output
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.

cmajor-external is a skill published in the GitHub repository Generous-Corp/pulp (16 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 630 once invoked, about $0.0002 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.
