harmont-cli: Skill for Claude Code

.claude/skills/write-pipeline/SKILL.md

write-pipeline is a skill for Claude Code from harmont-dev/harmont-cli. It costs 62 tokens per session (1,317 once invoked), scanned A, original, Apache-2.0.

A skill for writing and changing Harmont continuous-integration pipelines in `.hm/pipeline.py`. Continuous integration automatically builds and checks code when changes are made.

In plain words
What is it for?
Creating, modifying, extending, or migrating CI pipelines, including multi-pipeline setups and build-tool configuration.
Why use it?
It translates requests about build steps, triggers, caching, environment variables, and toolchains into Harmont pipeline changes using current documentation.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is harmont-dev/harmont-cli's own configuration. It tells Claude Code how to work on harmont-cli itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything harmont-cli configures →

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

write-pipeline 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 2mo 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

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Write, modify, or extend Harmont CI pipelines defined in .hm/pipeline.py. Pipelines are real Python programs that import the harmont SDK and declaratively define build steps, triggers, and caching.

When to use

  • The user asks to "set up CI", "add a pipeline", "write a pipeline", or "configure Harmont"
  • The user wants to add, remove, or modify pipeline steps
  • The user asks to add triggers, caching, or environment variables to a pipeline
  • The user wants to switch toolchains or add a new toolchain to their pipeline
  • The user asks to create a multi-pipeline setup
  • The user is migrating from another CI system and wants a Harmont pipeline

When NOT to use

  • The user only wants to run an existing pipeline — use the validate-ci skill instead
  • The user is debugging a build failure caused by their application code, not the pipeline definition
  • The user asks about Harmont Cloud features (login, org management, billing)

Before you start

  1. Fetch the patterns guide — the single most important reference:

    WebFetch https://docs.harmont.dev/pipeline-sdk/patterns.md

    Read it carefully. It covers correct vs. incorrect approaches, when to use toolchains vs. raw shell, and common anti-patterns.

  2. If you need the full API reference for a specific toolchain or feature, fetch the relevant page (append .md to any docs.harmont.dev URL for raw Markdown):

    • Toolchain reference: https://docs.harmont.dev/pipeline-sdk/reference/toolchains/<name>.md (rust, python, js, go, cmake, zig, elixir, etc.)
    • Chains and steps: https://docs.harmont.dev/pipeline-sdk/reference/chains.md
    • Triggers: https://docs.harmont.dev/pipeline-sdk/reference/triggers.md
    • Caching: https://docs.harmont.dev/pipeline-sdk/reference/cache.md
    • Pipeline decorator/factory: https://docs.harmont.dev/pipeline-sdk/reference/pipeline.md
    • Full page index: https://docs.harmont.dev/llms.txt

  3. If you need a complete working example for a language or framework:

    WebFetch https://docs.harmont.dev/examples/<language>.md

    Available examples: rust, go, cmake, zig, nextjs, python-uv, elixir

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.
