What it does

Accelerate Wrapper is an agent skill from JuliaLinearAlgebra/AppleAccelerate.jl. General method for building out AppleAccelerate.jl's coverage of the Apple Accelerate framework — for capabilities that do NOT exist yet as well as fixing ones that do. Given any Accelerate C symbol (vDSP, vForce, libSparse, BNNS, Quadrature, or a subframework not yet in scope), it takes you from scanning the header surface → generating the FFI binding → deriving a correct idiomatic Julian API from the C signature → cross-validated tests → docs → benchmarks, as one coherent pipeline. Use for adding new wrapped…

Its SKILL.md is about 4.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with macOS. The repository describes itself as: Julia interface to the macOS Accelerate framework.

When your agent uses it

  • Adding new wrapped functions
  • Whole new API families
  • Auditing coverage
  • Fixing correctness / memory-safety bugs in any wrapper

Example prompts

  • “/accelerate-wrapper”

Requirements

  • Python 3

Workflow steps

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

  1. Scan the surface
  2. Generate / extend the FFI bindings
  3. Derive the idiomatic API from the archetype
  4. Test: cross-validate against an independent package
  5. Document
  6. Benchmark

What it can do on your machine

Read from SKILL.md and the folder at commit 0b63e51. 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:

    • xcrun

    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

Accelerate Wrapper loads about 4.2k tokens when it runs. Until then it costs about 162 tokens; SKILL.md has 1,864 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~162
When it runs · the whole SKILL.md, loaded when a task matches
~4.2k

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 1,864 words (~4,172 tokens).

“This is a method, not a catalog. It works for a function whose family already has wrappers and for the first wrapper of a brand-new subframework. The existing modules are worked examples of a few archetypes — identify which archetype…”
