// tools roadmap

Scan a single source file for unused exports, orphan functions and types, unreachable statements, and stale imports — plus a fixpoint pass that cascades into transitively dead helpers. Returns a risk-ranked deletion queue with per-item LOC cost and a copyable Markdown report. Static heuristics only: confirm export findings with a repo-wide grep.

Paste a git log and rank every file by change risk: commit activity, recency-weighted activity, churn volume, author entropy, and fix ratio — blended into a 0–100 score with a risk heatmap and a click-to-expand ranked table. Static heuristics over past change patterns: it predicts instability, not defects. Scores are relative to the log you paste.

Rewrite a documented subset of Python into JavaScript and back: def/function, indentation/braces, if/elif/else, range and for..of loops, builtins, constants, and operators. Unsupported constructs are left verbatim and flagged per line in an annotations panel. Deterministic rewrite rules only — a starting point for a human port, not a compiler.

Apply a fixed set of refactorings — rename symbol, inline variable, extract function, convert to arrow function, replace var with let — to a pasted snippet and preview a line-level diff. Deterministic, scope-unaware rewrites with honest warnings; a documented subset, not an AST codemod. Supports Python, JS/TS, and Rust snippets.

Paste a `git diff` and get a structured Conventional Commits message: type, scope, imperative summary, grouped body bullets, and a breaking-change footer. Deterministic heuristics over the diff text — it classifies from changed paths, added symbols, and removed signatures, then shows you exactly which rule fired. Review and edit before you commit; it is a first draft, not a verdict.

Paste a source file and check it against Prettier, Black, gofmt, or rustfmt conventions: twelve deterministic text rules (indentation, quotes, semicolons, trailing commas, line length, whitespace) produce a per-rule findings list with line numbers, a 0–100 consistency score, and a rule-by-rule comparison of how the four formatters differ. A style-consistency checker — it flags drift, it does not reformat.

Rule-based rewrites for Express 4 → Fastify and React class → hooks, plus a custom rename table. Every change gets a line-numbered finding; constructs outside the rule tables go to a MANUAL REVIEW list and are never rewritten. No parser or type checker — a review aid, not a migration tool.

Paste two JavaScript implementations of the same function, run them on one seeded input, and compare wall-clock statistics (min, median, p95, spread, ops/sec) with a Proxy-counted array-access total and a growth exponent fitted from a size ladder. Two honest limits are printed on the page: the op counter goes blind after your code copies the array, and the exponent is an estimate from measured points, not a complexity proof.
