Configure, build and test pyGPlates. An agent skill from GPlates/GPlates.

  • Works in 5 steps: Check the environment → Configure → Build → …
  • Asked to build pyGPlates
  • SKILL.md covers 1. Check the environment, 2. Configure, 3. Build and 4. Test, plus 1 more section
  • Calls conda and cmake

What it does

Build Pygplates is an agent skill from GPlates/GPlates. Configure, build and test pyGPlates. Use when asked to build pyGPlates, rebuild after C++/Python API changes, or run the pyGPlates tests (pygplates-test, pygplates-stub-test).

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with C++ and Python. The repository describes itself as: GPlates is a program for visualising and manipulating plate tectonic reconstructions. PyGPlates is a Python package containing the core plate reconstruction functionality in…

When your agent uses it

  • Asked to build pyGPlates
  • Rebuild after C++/Python API changes
  • Run the pyGPlates tests (pygplates-test
  • Pygplates-stub-test)

Example prompts

  • “/build-pygplates”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Check the environment
  2. Configure
  3. Build
  4. Test
  5. Report

What it can do on your machine

Read from SKILL.md and the folder at commit d930b40. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • conda
    • cmake

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build Pygplates loads about 698 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 320 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~698

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 320 words (~698 tokens).

“Build directory is build-pygplates/ unless the user names another one.”
