axrl-run-regression-tests

Use this skill when the user asks to pass lint and then run the full axrl test suite on a GPU node, especially when benchmark or mismatch tables may need updating.

Required Sub-Skills

Load and follow these repo skills in order:

1. skills/axrl-fix-linting/SKILL.md
   • Run local lint/type validation first.
   • Keep fixes minimal and non-semantic.
   • Stop before changing logits, sampling, rewards, or training behavior unless the user explicitly approves.
2. skills/axrl-run-gpu-task/SKILL.md
   • Use its SSH, environment setup, progress-log, and remote execution workflow.
   • Run bash ltp/install.sh on each GPU node, then source ~/.axrl_env.sh, before GPU commands.

This skill only orchestrates those workflows and adds test-suite-specific retry, logging, and benchmark-table policy.

Defaults

• Progress file: use an explicit progress=... if provided; otherwise use agent-task/progress-run-tests.md.
• Full test command on the GPU node. scripts/run-tests.sh runs pytest with stdout passthrough (-s), streams pytest INFO logs into the main harness log with --log-level=INFO and --log-cli-level=INFO, and also writes a separate pytest INFO log, so expensive regression-table values are available without a focused rerun:

bash scripts/run-tests.sh

• Optional override for the pytest INFO log path:

AXRL_PYTEST_LOG_FILE="${AXRL_OUTPUT_DIR}/pytest-info-custom.log" bash scripts/run-tests.sh

• If the user gives an SSH target, use it. Otherwise resolve it through skills/axrl-run-gpu-task/SKILL.md.
• Do not stage, unstage, commit, reset, or otherwise modify Git index or history.

Workflow

1. Read both required sub-skills.
2. Initialize or update the progress file with the resolved SSH target, validation command, current status, and a timestamp.
3. Run bash scripts/run-precommit-check.sh locally by following axrl-fix-linting.
4. Fix lint/type failures minimally, then rerun the lint command until it passes or a semantic blocker is clearly recorded.
5. Follow axrl-run-gpu-task to prepare the GPU node and verify:
   • nvidia-smi works
   • ~/.axrl_env.sh is sourced
   • pip show axrl points at this shared working tree
6. Run the full GPU suite with bash scripts/run-tests.sh.
7. While any long GPU run is active, update the progress file at least every 5 minutes with:
   • running command and remote PID or log path
   • latest pass/fail/error summary
   • current test file or phase, if visible
   • retries or failures since the last update
   • any suspicious numeric results
8. For failures, record the failure in the progress file, rerun the narrowest failing test with enough logging, fix the root cause, rerun the focused test, then rerun the full suite.

Benchmark And Mismatch Tables

When tests print replacement numbers for tables such as R3 mismatch, benchmark, FP8 mismatch, or MoE benchmark snapshots:

• Always check these table-bearing regression files when their tests run or fail:
  • tests/magi-forward/test_magi_forward_r3_mismatch.py
  • tests/moe/test_r3_benchmark_results.py
  • tests/moe/test_fp8_mismatch_results.py
• First, try to extract the values from the full-run log files: ${AXRL_OUTPUT_DIR}/run-tests-*.log and ${AXRL_OUTPUT_DIR}/pytest-info-*.log.
• Rerun the focused test only if the full-run logs or persisted artifacts do not contain the needed table values. Use logging enabled, for example:

python -u -X faulthandler -m pytest <test-path-or-nodeid> -vv -s --log-cli-level=INFO --tb=long

• Update checked-in table values only from clearly logged test output for the same test/configuration.
• Keep table edits mechanical: numbers and surrounding expected text only.
• After a table update, rerun the focused test if the first full run did not already prove that exact table output. Then include it in the next full regression pass.

Potential Wrong Results To Report

Call out these even if the test process exits successfully:

• NaN or infinite metrics.
• KL, mismatch, off-policy, or routing values outside the intended range.
• Benchmark scores or throughput that drift sharply from the checked-in table.
• Missing train/eval metric names expected by existing GRPO users.
• Changes that suggest different behavior for the same GRPO config.
• Suspicious sample packing, prefix merging, MoE routing, data shuffling, or logging behavior observed in test output.

Done When

• Local bash scripts/run-precommit-check.sh passes.
• Remote bash scripts/run-tests.sh passes on the GPU node.
• Any benchmark table updates are supported by focused logged output.
• The progress file records the final commands, evidence, failures/retries, potential wrong-result notes, and final status.
