From 3bfc0f68455c9043cecd7db855542b898f478c2f Mon Sep 17 00:00:00 2001 From: Tom Boucher Date: Mon, 16 Mar 2026 20:31:45 -0400 Subject: [PATCH 1/3] fix: add --no-verify support for parallel executor commits (#1116) Parallel executor agents trigger pre-commit hooks on every commit, causing build lock contention (e.g., cargo lock fights in Rust projects) and 40+ minute delays from cascading retries. Changes: - Add --no-verify flag to gsd-tools commit command (commands.cjs) - Wire --no-verify through gsd-tools.cjs CLI parser - Update execute-phase.md to instruct parallel agents to use --no-verify - Add post-wave hook validation step so orchestrator runs hooks once - Update execute-plan.md pre-commit handling: parallel agents skip hooks, sequential agents still handle hooks normally - Add parallel agent note to git-integration.md reference Fixes #1116 --- get-shit-done/bin/gsd-tools.cjs | 5 +++-- get-shit-done/bin/lib/commands.cjs | 5 +++-- get-shit-done/references/git-integration.md | 4 ++++ get-shit-done/workflows/execute-phase.md | 20 +++++++++++++++++++- get-shit-done/workflows/execute-plan.md | 8 +++++--- 5 files changed, 34 insertions(+), 8 deletions(-) diff --git a/get-shit-done/bin/gsd-tools.cjs b/get-shit-done/bin/gsd-tools.cjs index cdee42566..02915d58b 100755 --- a/get-shit-done/bin/gsd-tools.cjs +++ b/get-shit-done/bin/gsd-tools.cjs @@ -19,7 +19,7 @@ * state signal-resume Remove WAITING.json signal * resolve-model Get model for agent based on profile * find-phase Find phase directory by number - * commit [--files f1 f2] Commit planning docs + * commit [--files f1 f2] [--no-verify] Commit planning docs * verify-summary Verify a SUMMARY.md file * generate-slug Convert text to URL-safe slug * current-timestamp [format] Get timestamp (full|date|filename) @@ -290,6 +290,7 @@ async function main() { case 'commit': { const amend = args.includes('--amend'); + const noVerify = args.includes('--no-verify'); const filesIndex = args.indexOf('--files'); // Collect all positional args between command name and first flag, // then join them — handles both quoted ("multi word msg") and @@ -298,7 +299,7 @@ async function main() { const messageArgs = args.slice(1, endIndex).filter(a => !a.startsWith('--')); const message = messageArgs.join(' ') || undefined; const files = filesIndex !== -1 ? args.slice(filesIndex + 1).filter(a => !a.startsWith('--')) : []; - commands.cmdCommit(cwd, message, files, raw, amend); + commands.cmdCommit(cwd, message, files, raw, amend, noVerify); break; } diff --git a/get-shit-done/bin/lib/commands.cjs b/get-shit-done/bin/lib/commands.cjs index d7109df19..b7416a1b3 100644 --- a/get-shit-done/bin/lib/commands.cjs +++ b/get-shit-done/bin/lib/commands.cjs @@ -214,7 +214,7 @@ function cmdResolveModel(cwd, agentType, raw) { output(result, raw, model); } -function cmdCommit(cwd, message, files, raw, amend) { +function cmdCommit(cwd, message, files, raw, amend, noVerify) { if (!message && !amend) { error('commit message required'); } @@ -241,8 +241,9 @@ function cmdCommit(cwd, message, files, raw, amend) { execGit(cwd, ['add', file]); } - // Commit + // Commit (--no-verify skips pre-commit hooks, used by parallel executor agents) const commitArgs = amend ?

The second definition shadowed the first with identical logic. Keeps the original that uses escapeRegex() from core.cjs. 2. init.cjs: Replace Unix-only 'find' pipe with cross-platform fs.readdirSync recursive walk for code file detection. The execSync('find ... | grep ...') command fails on Windows where these Unix utilities aren't available. Removes unused child_process import. 3. state.cjs: Add lockfile-based mutual exclusion to writeStateMd() to prevent parallel executor agents from overwriting each other's STATE.md changes. Uses O_EXCL atomic file creation for lock acquisition, stale lock detection (10s timeout), and spin-wait with jitter. Ensures data integrity during wave-based parallel execution where multiple agents update STATE.md concurrently. All 755 existing tests pass. --- get-shit-done/bin/lib/init.cjs | 25 +++++++++----- get-shit-done/bin/lib/state.cjs | 59 +++++++++++++++++++++++++-------- 2 files changed, 63 insertions(+), 21 deletions(-) diff --git a/get-shit-done/bin/lib/init.cjs b/get-shit-done/bin/lib/init.cjs index 9c9d35655..bcac25560 100644 --- a/get-shit-done/bin/lib/init.cjs +++ b/get-shit-done/bin/lib/init.cjs @@ -167,17 +167,26 @@ function cmdInitNewProject(cwd, raw) { const braveKeyFile = path.join(homedir, '.gsd', 'brave_api_key'); const hasBraveSearch = !!(process.env.BRAVE_API_KEY || fs.existsSync(braveKeyFile)); - // Detect existing code + // Detect existing code (cross-platform — no Unix `find` dependency) let hasCode = false; let hasPackageFile = false; try { - const files = execSync('find . -maxdepth 3 \\( -name "*.ts" -o -name "*.js" -o -name "*.py" -o -name "*.go" -o -name "*.rs" -o -name "*.swift" -o -name "*.java" \\) 2>/dev/null | grep -v node_modules | grep -v .git | head -5', { - cwd, - encoding: 'utf-8', - stdio: ['pipe', 'pipe', 'pipe'], - }); - hasCode = files.trim().length > 0; - } catch {} + const codeExtensions = new Set(['.ts', '.js', '.py', '.go', '.rs', '.swift', '.java']); + const skipDirs = new Set(['node_modules', '.git', '.planning', '.claude', '__pycache__', 'target', 'dist', 'build']); + function findCodeFiles(dir, depth) { + if (depth > 3) return false; + let entries; + try { entries = fs.readdirSync(dir, { withFileTypes: true }); } catch { return false; } + for (const entry of entries) { + if (entry.isFile() && codeExtensions.has(path.extname(entry.name))) return true; + if (entry.isDirectory() && !skipDirs.has(entry.name)) { + if (findCodeFiles(path.join(dir, entry.name), depth + 1)) return true; + } + } + return false; + } + hasCode = findCodeFiles(cwd, 0); + } catch { /* intentionally empty — best-effort detection */ } hasPackageFile = pathExistsInternal(cwd, 'package.json') || pathExistsInternal(cwd, 'requirements.txt') || diff --git a/get-shit-done/bin/lib/state.cjs b/get-shit-done/bin/lib/state.cjs index 78797694a..ca6d1f40f 100644 --- a/get-shit-done/bin/lib/state.cjs +++ b/get-shit-done/bin/lib/state.cjs @@ -180,18 +180,7 @@ function cmdStateUpdate(cwd, field, value) { } // ─── State Progression Engine ──────────────────────────────────────────────── - -function stateExtractField(content, fieldName) { - const escaped = fieldName.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); - // Try **Field:** bold format first - const boldPattern = new RegExp(`\\*\\*${escaped}:\\*\\*\\s*(.+)`, 'i'); - const boldMatch = content.match(boldPattern); - if (boldMatch) return boldMatch[1].trim(); - // Fall back to plain Field: format - const plainPattern = new RegExp(`^${escaped}:\\s*(.+)`, 'im'); - const plainMatch = content.match(plainPattern); - return plainMatch ?
