Which Linear task belongs to this PR?

Fixes EXSC-1273

Why did I implement it this way?

The pre-commit hook took minutes on large commits and could fail in fresh worktrees. The secret scan ran one grep per .env value per staged file (~75k processes on a 338-file merge), and lint-staged's type check raced forge build + TypeChain generation, which ran in parallel with it.

The hook now does only what has to happen before a commit: block .env secrets and run the staged-file formatters/linters (lint-staged, unchanged).

• Secret scan moved to script/utils/scan-staged-secrets.sh and scans only the lines the commit adds: one git diff --cached, one git grep --no-index -F over all .env values (BSD grep is ~20x slower with hundreds of fixed patterns), one grep -E for private keys. Content already in history cannot leak anything new, so merges from main no longer re-scan main. Findings format, the pre-commit-checker: not a secret marker (same line or line above), .env value filtering, exclusions, blocking on .env hits and warn-only private keys are unchanged. Binary files are still scanned (as text); the scan runs with LC_ALL=C, because under a UTF-8 locale macOS tr aborts on bytes that are not valid UTF-8. On a 340-file / 224-value benchmark: old scan 377 s, new 1.25 s, identical findings.
• Removed forge build, TypeChain generation and the tsc-files step from the hook. The tsc-files step was a no-op (called without file arguments, tsc-files exits 0). Contract builds and TypeChain generation run in CI only (forge-unit-tests, validateScripts). No coverage is lost: a Solidity ABI change that breaks a TS script the commit leaves untouched was not caught by the old hook and is not caught by CI either, because validateScripts skips PRs that only modify .sol files and type-checks only changed TS files. Closing that gap is tracked in EXSC-1313.
• The hooks never build contracts. typechain/, diamond.json and out/ are gitignored build outputs, imported by script/demoScripts/ and, through demoScriptHelpers.ts, by scripts such as deploy-safe.ts and the Tron deploy scripts. While one is absent, script/utils/typecheck-files.sh ignores every error in a file that cannot find it (the missing module and the errors that follow from it) with a notice, and still fails on errors in any other file and on any tool output that is not a tsc error. With CI set nothing is ignored, so CI's validateScripts checks the PR's changed TS files against freshly generated outputs. docs/Setup.md documents bun build:typechain-and-abi for generating them locally.
• The secret scan pins diff.suppressBlankEmpty=false and git grep --no-line-number --no-column, so user git config cannot desync the hunk parser or prefix reported paths.
• The lint-staged output colorizer is one sed instead of 19 per line; shellcheck is clean on the hook.

scan-staged-secrets.test.ts runs the script against throwaway repos (27 cases). typecheck-files.test.ts covers tsconfig routing and which errors are ignored or still fail, replaying tsc output through a stubbed bunx; the same rule was also run with real tsc on 25 build-output importers with typechain/ removed.

Walkthrough

The pre-commit hook delegates staged secret scanning to a script and runs lint-staged synchronously. The typecheck helper filters errors linked to missing generated outputs outside CI. Setup guidance describes generating those outputs, and the PR guidance identifies checks that do not run at commit time.

Changes

Developer checks

Layer / File(s)	Summary
Staged secret scanner script/utils/scan-staged-secrets.sh, script/utils/scan-staged-secrets.test.ts	The scanner checks staged added lines against selected .env values and warns about Ethereum-shaped values. Tests cover matching, exclusions, reporting, and exit statuses.
Pre-commit check flow .agents/commands/create-pr.md, .husky/pre-commit	The hook delegates secret scanning and runs lint-staged synchronously. It captures and filters failure output. The PR guidance identifies forge build and bun test:ts as checks that do not run at commit time.
Local typecheck and build outputs script/utils/typecheck-files.sh, script/utils/typecheck-files.test.ts, docs/Setup.md, .agents/commands/resolve-audit-issues.md, .agents/hooks/post-edit-validate.sh, script/utils/validateScripts.ts	Outside CI, the typecheck helper filters errors tied to missing generated outputs when no other judged errors remain. Setup guidance describes generating typechain/ and diamond.json. Related hooks and validation commands update their output and setup behavior.

Merge Risk: Low · up to b0ea1

If a local .env file cannot be read, a commit containing one of its secrets may pass the check. Fix the scanner’s failure handling before relying on that protection.

Full details: Title check

Explanation

The title uses the conventional commit form and names the main change, making the pre-commit hook faster and deterministic. It also cites the Linear task. The changeset moves secret scanning to a diff-only script, removes forge build, TypeChain, and tsc-files from the hook, and adds typecheck handling for absent outputs. The title covers the main goal, though it does not name the specific mechanisms.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 6 files. (3 skipped: 3 unsupported.)

Full details: Description check

Explanation

The description follows the repository template. It names the Linear task (EXSC-1273) and explains the design in detail, covering the secret-scan move, removal of forge build, TypeChain, and tsc-files from the hook, the absent-output rule in typecheck-files.sh, and the docs update. Testing is described: scan-staged-secrets.test.ts (27 cases) and typecheck-files.test.ts, plus a real tsc run on 25 importers. The self-review, testing, and documentation checklist items are checked. Facet and reviewer audit items are unchecked. Those items apply only to contract changes, and this PR changes no contracts. The description also says the test count is 25 in one place and 27 in another, which is a small inconsistency. The PR objectives also say 25 cases.

🔗 Pull Request #2623 · head d91185fd42f3 · 🔁 Re-review (post-approval) of 3f82d0e6535e · Critical 0 · High 0 · Medium 0 · Low 0 · Awaiting response: 0

Summary

New commits since the approved head touch .husky/pre-commit, docs/Setup.md, script/utils/scan-staged-secrets.sh and its test. The scan now exports LC_ALL=C so BSD tr/grep do not abort on invalid UTF-8 (PDFs, binaries), with a new test covering clean and leaking invalid-UTF-8 files. The hook is updated for husky 9 (LIFI_HOOK_BASH re-exec guard, ~/.huskyrc still sourced, HUSKY=0 honoured) and filters lint-staged status glyph lines. Setup docs now say Node 26+ and Bun via packageManager.

Resolution Status

Prior review had 0 findings; nothing to carry forward.

Findings

None. The original goals still hold: one git diff --cached plus one git grep -F -f (cost scales with the diff), no build steps, no locale dependence, .env values and key regex unchanged, rename/delete/space-in-name handling unchanged, unreadable .env still fails closed, and .env hits print only the key name.

Refuted candidates

• ${#VALUE} counts bytes under LC_ALL=C — stricter, not weaker.
• LIFI_HOOK_BASH leaking into nested hooks — the old husky_skip_init was exported the same way.
• New glyph filter hiding errors — only status lines are dropped; errors and warnings are kept, with a raw-output fallback.

Audit

No src/ change, so no audit entry is required.
