What it does

Golang Performance is an agent skill from aiskillstore/marketplace. Go performance optimization techniques including profiling with pprof, memory optimization, concurrency patterns, and escape analysis.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).

It sits in Development, covering Performance optimization. It works with Go. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Tasks that involve Performance optimization

Example prompts

  • “/golang-performance”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Measure before optimizing - Profile to find actual bottlenecks
  2. Pre-allocate slices - Use make([]T, 0, capacity) when size is known
  3. Pool frequently allocated objects - Use sync.Pool for buffers
  4. Minimize allocations in hot paths - Reuse objects, avoid interfaces
  5. Right-size channels - Buffer to reduce blocking without wasting memory
  6. Avoid premature optimization - Clarity first, optimize measured problems
  7. Use value receivers for small structs - Avoid pointer indirection
  8. Order struct fields by size - Largest to smallest reduces padding

What it can do on your machine

Read from SKILL.md and the folder at commit 755bc35. 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:

    • go

    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

Golang Performance loads about 2.3k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 220 words (~2,252 tokens).

“This skill provides guidance on optimizing Go application performance including profiling, memory management, concurrency optimization, and avoiding common performance pitfalls.”
