At a glance

Design and run Triton TTGIR debugging ablations using iroverride.

  • Works in 3 steps: Identify the target signal before editing → Get a baseline TTGIR → Decide the override mechanism
  • Reducing a provided
  • SKILL.md covers Setup, Ablation Loop, Harness Rules and Reporting, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Ir Override Ablation is an agent skill from facebookexperimental/triton, published by the product's own GitHub organization. Design and run Triton TTGIR debugging ablations using iroverride. Use when reducing a provided or dumped TTGIR, trying user-provided or agent-generated ablation/oblation ideas, updating a test harness around iroverride, or preserving a compile/runtime failure while simplifying IR to expose a fundamental compiler or lowering gap.

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/harness-template.md` and `references/variant-manifest-template.md`).

It sits in Development. The repository describes itself as: Github mirror of trition-lang/triton repo. The licence is MIT.

When your agent uses it

  • Reducing a provided
  • Trying user-provided
  • Agent-generated ablation/oblation ideas
  • Updating a test harness around iroverride

Example prompts

  • “/ir-override-ablation”

Requirements

  • Python 3

Workflow steps

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

  1. Identify the target signal before editing
  2. Get a baseline TTGIR
  3. Decide the override mechanism

What it can do on your machine

Read from SKILL.md and the folder at commit 37301d4. 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

Ir Override Ablation loads about 978 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 88 tokens; SKILL.md has 471 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~88
When it runs · the whole SKILL.md, loaded when a task matches
~978
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

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.

description
Design and run Triton TTGIR debugging ablations using ir_override. Use when reducing a provided or dumped TTGIR, trying user-provided or agent-generated ablation/oblation ideas, updating a test harness around ir_override, or preserving a compile/runtime failure while simplifying IR to expose a fundamental compiler or lowering gap.

IR Override Ablation

Use this skill to turn a noisy TTGIR reproducer into a smaller, evidence-backed set of IR variants. The goal is not only to simplify the IR; it is to preserve the debugging signal and keep the test oracle honest when edits intentionally change kernel semantics.

Setup

  1. Identify the target signal before editing:
    • compile failure, pass assertion, crash, hang, wrong result, or diagnostic
    • the exact command and environment that reproduces it
    • the minimum architecture requirement, for example sm90 or sm100
  2. Get a baseline TTGIR:
    • Use the provided .ttgir directly when available.
    • Otherwise dump it with:
      bash
      TRITON_ALWAYS_COMPILE=1 TRITON_KERNEL_DUMP=1 TRITON_DUMP_DIR=<dump_dir> <run_command>
  3. Decide the override mechanism:
    • Prefer triton.Config(..., ir_override="<variant.ttgir>") when the harness already uses configs/autotune or can be cheaply adapted.
    • Use TRITON_KERNEL_OVERRIDE=1 TRITON_OVERRIDE_DIR=<dump_dir> when testing against the dumped override directory layout is simpler.

Ablation Loop

  1. Build or accept a list of ideas. Each idea should state the hypothesis and the expected effect on the target signal.
  2. Copy the baseline TTGIR to a named variant file before editing.
  3. Classify the test oracle before running the variant:
    • preserve: the original numeric/reference output must still match.
    • replace: the edit intentionally changes output values; update the expected output to match the new semantics.
    • relax: success is reproducing a compile failure, crash, hang, or diagnostic; numeric equality is not the primary oracle.
    • observe: temporary exploration only; do not treat this as final evidence.
  4. Update the harness when the oracle is not preserve.
    • Example: if a store operand is replaced by a constant tensor, expected output must become that constant over the same mask/shape, not the original reference computation.
    • If an edit removes a store, expected output may need to assert unchanged sentinel values instead of comparing to the old result.
  5. Run exactly the command recorded for the variant with TRITON_ALWAYS_COMPILE=1 to avoid cache reuse.
  6. Record whether the target signal survives, weakens, disappears, or changes into a different failure.
  7. Prefer single-concept edits. When multiple edits are needed, stage them as separate variants so the final reproducer has a defensible chain of evidence.

Harness Rules

  • Keep baseline and variant runs side by side until the final reproducer is chosen.
  • Make oracle-changing behavior explicit in code or comments near the assertion.
  • For wrong-result bugs, keep at least one shape that fails and one nearby shape that passes when practical.
  • For hangs, set a short external timeout and run third_party/tlx/killgpu.sh if the GPU process survives longer than expected.
  • Do not run performance benchmarks unless the user explicitly asks.

Reporting

Return a compact result matrix:

text
variant | hypothesis | oracle | result | target signal | kept?

Then state the smallest surviving reproducer, the concepts still present in the IR, and the concepts successfully removed.

References

  • Use references/variant-manifest-template.md when tracking more than a few ideas or when handing work to another agent.
  • Use references/harness-template.md when creating or adapting the Python harness around ir_override.
