Absolute Debt
Pay down accumulated lint and type-checker debt across the repo — existing warnings,
errors, and suppressions that built up over time — in safe waves, by rule, with tests green
after each. The goal is a genuinely clean lint + typecheck, not a quieter one.
Runs the shared engine in references/health-engine.md — read it for the
DETECT → SCAN → TRIAGE → FIX → VERIFY → REPORT loop and the safety contract. This file
covers only what's specific to lint/type debt.
When to use
- "Fix our lint warnings", "clean up the type errors", "get the codebase to strict mode".
- Tightening config (enable a rule, raise
tsconfig strictness) and clearing the fallout.
- Burning down accumulated
eslint-disable / @ts-ignore / # type: ignore suppressions.
debt vs simplify: simplify improves your working diff's quality. debt clears
pre-existing repo-wide lint/type violations on green main. Use debt for standing
cleanup, not for changes you're actively making.
What it scans
| Ecosystem |
Lint debt |
Type debt |
| JS/TS |
eslint . (full report, by rule) |
tsc --noEmit |
| Python |
ruff check / flake8 |
mypy / pyright |
| Go |
golangci-lint run |
go vet ./..., staticcheck |
Also inventory suppressions as debt in their own right: eslint-disable*,
@ts-ignore/@ts-expect-error, # type: ignore, # noqa, //nolint. Each is a hidden
violation. Count violations grouped by rule (not by file) — that's how you wave them.
Risk ranking (TRIAGE)
| Wave |
Class |
Default |
| 1 |
autofixable lint (eslint --fix, ruff --fix, gofmt) |
fix now — mechanical, safe |
| 2 |
manual lint by rule, low behavioral risk (unused, style, imports) |
fix this pass, one rule at a time |
| 3 |
type errors, and lint rules that can change behavior if "fixed" wrong |
gated — review each, may need real logic |
| 4 |
removing suppressions (@ts-ignore etc.) |
gated — each may surface a real bug |
Fix one rule across the repo per wave, not one file across all rules — keeps diffs
reviewable and regressions bisectable. Config tightening (enable rule / raise strictness) is
itself a finding: propose it, then clear what it surfaces.
Fix & verify
- Run the autofixers first (wave 1), commit-ready, then re-scan to see what's truly manual.
- Manual fixes: address the cause, not the symptom. A type error means the types are
wrong somewhere — fix the type, don't cast to
any/add # type: ignore.
- Never clear a violation by suppressing it. Removing suppressions is the goal, not a tool.
- After each wave: full test + lint + typecheck + build. The violation count must drop and
nothing regress.
Gotchas
- Fixing by suppressing.
@ts-ignore to clear a type error adds debt. Forbidden here.
any / cast to win. Silences the checker, keeps the bug. Fix the real type.- One-file-all-rules waves. Mixes concerns, unreviewable. Go one-rule-all-files.
- Autofix without review.
--fix can change behavior (e.g. prefer-const on a
reassigned var via a bug). Run tests after autofix too.
- Disabling the rule instead of fixing. Loosening config to hit zero is debt laundering,
not paydown.
