Install Add Op

skills CLI
$ npx skills add hw-native-sys/pypto --skill add-op -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install hw-native-sys/pypto add-op --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/hw-native-sys/pypto.git skills-src && mkdir -p .claude/skills && cp -r skills-src/.claude/skills/add-op .claude/skills/add-op && rm -rf skills-src

At a glance

Add new operator definitions to PyPTO across all layers (C++, Python IR, Python DSL, tests, codegen, docs).

  • The user asks to add a new op
  • SKILL.md covers Overview, Task Tracking, Phase A: Tile Op and Phase B: Tensor Op + Conversion, plus 2 more sections
  • Calls python3
  • Define a new operator

What it does

Add Op is an agent skill from hw-native-sys/pypto. Add new operator definitions to PyPTO across all layers (C++, Python IR, Python DSL, tests, codegen, docs). Covers tile ops, tensor ops, tensor-to-tile conversion, and codegen registration. Use when the user asks to add a new op, define a new operator, implement a new tile/tensor operation, or extend the operator system.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Development, covering Project scaffolding. It works with C++ and Python. The repository describes itself as: A community-driven pypto implementation.

When your agent uses it

  • The user asks to add a new op
  • Define a new operator
  • Implement a new tile/tensor operation
  • Extend the operator system

Example prompts

  • “/add-op”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 5f71449. 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:

    • python3

    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

Add Op loads about 2k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 835 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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 835 words (~2,050 tokens).
