What it does

Hipfire Kernel Tuning is an agent skill from warpfront/hipfire. Optimize hipfire HIP/compute kernels — pick one tuning lever (multi-row, K-tile depth, prefetch, wave-size port, WMMA/MFMA, fused projections, ISA flags) and validate it with profile → ISA → fresh-process measurement. Use when a hot kernel is identified, you want a real perf win, and you must not regress adjacent archs or promote unverified deltas. Codifies the methodology from this repo's perf history (wave64 CDNA3 port 4105035, nontemporal-load revert 34eb024, gfx12 WMMA PR

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `case-studies.md`, `cross-arch.md` and `levers.md`).

It sits in AI & LLM Engineering. The repository describes itself as: RDNA-native LLM inference engine in Rust.

When your agent uses it

  • A hot kernel is identified
  • You want a real perf win
  • You must not regress adjacent archs
  • Promote unverified deltas

Example prompts

  • “/hipfire-kernel-tuning”

Workflow steps

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

  1. playbook.md — profile → root-cause → one lever → source/ISA inspect
  2. levers.md — catalog of patterns that shipped or failed in this tree,
  3. cross-arch.md — file tags, dispatch fall-through, "no unreachable
  4. case-studies.md — worked wins, fake wins, null results, and silent

What it can do on your machine

Read from SKILL.md and the folder at commit 0f999cb. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Hipfire Kernel Tuning loads about 1.7k tokens when it runs. Until then it costs about 126 tokens; SKILL.md has 607 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~126
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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 607 words (~1,669 tokens).

“Land real kernel perf wins without inventing a universal gate, shipping measurement noise, or silently regressing an adjacent arch.”
