coverage

Measures coverage in outl-core via cargo-llvm-cov. Focuses on the 4 critical functions (doop, undoop, applyop, createscycle) that must be at 100%.

Made for: Claude Code.

Per session 41 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 259 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

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 yesterday.

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

Target: ${1:-outl-core}

  1. If cargo llvm-cov is not installed, install it (cargo install cargo-llvm-cov --locked).

  2. Run:

    cargo llvm-cov -p ${1:-outl-core} --html --output-dir target/llvm-cov
    cargo llvm-cov -p ${1:-outl-core} --summary-only
    
  3. Report:

    • Total coverage
    • Specific coverage of tree::do_op, tree::undo_op, tree::apply_op, tree::creates_cycle (must be 100%)
    • Top 5 functions with the worst coverage
  4. If critical coverage < 100%, list the uncovered branches with cargo llvm-cov report --show-missing-lines -p ${1:-outl-core}.

Changes

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.

coverage is a command published in the GitHub repository outlmd/outl (161 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 259 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 2026-09-01.
