Enable three unicorn rules — one correctness, two performance — and fix every
existing violation repo-wide so the rules pass as errors.
prefer-number-properties (76 sites)
- parseInt/parseFloat/NaN -> Number.* : safe aliases (autofixed).
- isNaN -> Number.isNaN (12 sites, hand-converted): global isNaN coerces its
argument, Number.isNaN does not. Verified every call site already passes a
number (Number.parseInt results, number-typed fields, Date.getTime()), so the
conversion is behavior-preserving today and guards against a future non-numeric
argument silently coercing.
prefer-array-find (26 sites)
- .filter(pred)[0] -> .find(pred); .filter(pred).at(-1) / .pop() -> .findLast(pred).
Drops the intermediate array and short-circuits.
prefer-array-index-of (5 sites)
- .findIndex(x => x === v) -> .indexOf(v).
Verified: typecheck (node/cli/web) clean, 53 affected suites pass (1679 tests),
oxlint clean repo-wide. mobile/ uses findLast safely (already ships ES2023
.toReversed()); config scripts and e2e helpers run on Node 24.
Identify specific agents (e.g., codex, gemini, aider) running under
interpreter wrappers like node or python by querying and inspecting
descendant process tables.
- Add Windows process-tree queries using PowerShell and WMIC.
- Support deep process inspection on remote SSH relays.
- Retry wrapper checks in OrcaRuntime for delayed async cache resolution.
- Prevent false positives by validating only recognized agent processes.
