Left alone, the hooks treat it as a\n * session in its own right: they inject project context into it, create and\n * rename a numbered session note for it, autosave it, and enqueue a\n * model-written handover for it. Its compactions also land in the project's\n * transcript folder, where they are indistinguishable from a real session's\n * and drag the measured compaction trigger down (observed 2026-09-17: two\n * workers compacting at ~151k tokens pulled a project's trigger from ~784k\n * to ~151k, and the real session's handover fired at ~50k tokens).\n *\n * The launcher marks such sessions with `PAI_WORKER=1`. Every hook that does\n * per-session bookkeeping returns immediately when this predicate is true.\n * Deliberately NOT guarded: the security validator (a worker's shell\n * commands must still be checked) and observability capture.\n */\nexport function isWorkerSession(env: NodeJS.ProcessEnv = process.env): boolean {\n  return env.PAI_WORKER === \"1\";\n}\n", "#!/usr/bin/env node\n/**\n * Tab Title Update Hook\n * Updates tab title based on user prompt\n *\n * Note: All context loading handled by PAI skill system (core identity in skill description, full context in SKILL.md)\n */\n\nimport { isWorkerSession } from \"../lib/worker-session.js\";\nimport { execSync } from 'child_process';\n\ninterface HookInput {\n  session_id: string;\n  prompt: string;\n  transcript_path: string;\n  hook_event_name: string;\n}\n\n/**\n * Read stdin with timeout\n */\nasync function readStdinWithTimeout(timeout: number = 5000): Promise<string> {\n  return new Promise((resolve, reject) => {\n    let data = '';\n    const timer = setTimeout(() => {\n      reject(new Error('Timeout reading from stdin'));\n    }, timeout);\n\n    process.stdin.on('data', (chunk) => {\n      data += chunk.toString();\n    });\n\n    process.stdin.on('end', () => {\n      clearTimeout(timer);\n      resolve(data);\n    });\n\n    process.stdin.on('error', (err) => {\n      clearTimeout(timer);\n      reject(err);\n    });\n  });\n}\n\nasync function main() {\n  if (isWorkerSession()) return; // disposable worker: no per-session bookkeeping\n  try {\n    // Read the hook input from stdin\n    const input = await readStdinWithTimeout();\n    const data: HookInput = JSON.parse(input);\n\n    const prompt = data.prompt || '';\n\n    // UPDATE TAB TITLE\n    // Generate quick fallback tab title\n    let tabTitle = 'Processing request...';\n    if (prompt) {\n      const words = prompt.replace(/[^\\w\\s]/g, ' ').trim().split(/\\s+/)\n        .filter(w => w.length > 2 && !['the', 'and', 'but', 'for', 'are', 'with', 'you', 'can'].includes(w.toLowerCase()))\n        .slice(0, 3);\n\n      if (words.length > 0) {\n        tabTitle = words[0].charAt(0).toUpperCase() + words[0].slice(1).toLowerCase();\n        if (words.length > 1) {\n          tabTitle += ' ' + words.slice(1).map(w => w.toLowerCase()).join(' ');\n        }\n        tabTitle += '...';\n      }\n    }\n\n    // Set initial tab title with recycle emoji\n    try {\n      const titleWithEmoji = '\u267B\uFE0F ' + tabTitle;\n      const escapedTitle = titleWithEmoji.replace(/'/g, \"'\\\\''\");\n      execSync(`printf '\\\\033]0;${escapedTitle}\\\\007' >&2`);\n      execSync(`printf '\\\\033]2;${escapedTitle}\\\\007' >&2`);\n      execSync(`printf '\\\\033]30;${escapedTitle}\\\\007' >&2`);\n    } catch (e) {\n      // Silently fail\n    }\n\n    process.exit(0);\n  } catch (error) {\n    // Silently fail to not interrupt Claude's flow\n    console.error('Tab title update error:', error);\n    process.exit(0);\n  }\n}\n\nmain();\n"],
