running-coverage

A procedure for running all test suites in the paddler workspace and producing a code-coverage report. Code coverage shows which parts of the code are exercised by tests.

In plain words
What is it for?
Use it when checking workspace coverage, running the complete test suite, detecting tests that exceed 30 seconds, and summarizing the results.
Why use it?
It standardizes device selection, test execution, GPU scheduling, timeout checks, and result reporting, making slow or failing tests easier to identify.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

running-coverage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Running the code coverage

Run every test suite in the workspace, picking the fastest compiled device backend for the host, then report the workspace code coverage.

Step 1: detect the device

Run this once at the start and echo the chosen device:

if [[ "$OSTYPE" == "darwin"* ]]; then
  DEVICE=metal
elif command -v nvidia-smi >/dev/null 2>&1 && nvidia-smi >/dev/null 2>&1; then
  DEVICE=cuda
else
  DEVICE=cpu
fi
echo "Device: $DEVICE"

$DEVICE selects the Rust integration suite variant in Step 2. The other four suites don't take a device feature.

Step 2: run the code coverage

Copy this checklist and tick each item as the suite completes:

TEST_DEVICE=$DEVICE make test.coverage

Step 3: rules during the run

  • Serialize GPU suites. When $DEVICE is cuda or metal, run test suites sequentially to avoid device contention.
  • Per-test 30 s budget. Flag any individual test that exceeds 30 s wall-clock. That is a real bug — production or test — not flakiness.

Step 4: report

After the coverage suite finishes, sum up the results in an actionable report.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

running-coverage is a skill published in the GitHub repository intentee/paddler (1,666 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 42 tokens to every session and 331 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
