Use this skill when a project schedule is needed - "buat timeline", "kapan selesai", "susun milestone", "roadmap", work breakdown, estimating a project, sprint planning, or re-planning after a slip. Produces a dependency-aware timeline with buffers and a critical path. Do NOT use for writing requirements (prd-creator) or tracking meeting decisions (admin-ops).

Project Timeline Creator
A timeline is a chain of dependencies with buffers - not a wish list with dates. Its quality is measured by how early it predicts a slip, not by how optimistic it looks.
Build order (never skip 1-3 to jump to dates)
- Breakdown: pecah scope (dari PRD) jadi work item ≤ 2 hari kerja. Item > 2 hari = belum dipahami, pecah lagi. Sertakan item non-kode: desain, review, testing, deploy, dokumentasi, approval pihak lain.
- Dependency map: per item, apa yang harus selesai duluan? Tandai dependency eksternal (API pihak ketiga, keputusan klien, konten dari tim lain) - ini sumber slip terbesar dan harus dikejar paling awal, bukan paling akhir.
- Estimate: per item, optimis & realistis (jam/hari). Pakai realistis. Total fase × 1.5 buffer (integrasi, bolak-balik review, hal tak terduga). Jangan sembunyikan buffer di tiap item - taruh eksplisit sebagai baris buffer per fase, supaya terlihat saat dimakan.
- Critical path: rantai terpanjang item yang saling menunggu = durasi minimum proyek. Sebut eksplisit item mana yang di critical path - item ini tidak boleh menunggu resource.
- Milestones: 3-7 titik yang bisa diverifikasi ("staging bisa dipakai klien uji", bukan "development 80%"). Tiap milestone punya demo/bukti.
Output format
# Timeline <project> - v1 (tanggal, asumsi kapasitas: X orang/jam per minggu)
## Milestones
| M | Deliverable (bisa didemo) | Target | Gate |
## Breakdown per fase
| Item | Estimasi | Dependency | PIC | Critical path? |
| Buffer fase | (1.5× eksplisit) |
## Dependency eksternal & tanggal butuhnya (kejar sekarang)
## Risiko jadwal (top 3) + mitigasi
## Asumsi (kapasitas, scope beku per PRD vX, tanggal mulai)Rules of master-level scheduling
- Student syndrome & Parkinson: deadline per milestone, bukan hanya deadline akhir - kerja mengembang mengisi waktu yang diberikan.
- Jangan menjadwalkan utilisasi 100%; 70-80% kapasitas. Sisanya termakan interupsi, itu fakta bukan kegagalan.
- Fitur berisiko/gelap dikerjakan paling awal (de-risk dulu), bukan yang paling gampang dulu.
- Satu sumber kebenaran: timeline hidup di satu dokumen; update tercatat dengan tanggal & alasan.
- Tanggal yang dijanjikan keluar (ke klien) = tanggal internal + buffer komunikasi; jangan pernah janjikan tanggal critical-path mentah.
When it slips (it will)
- Deteksi dini: milestone meleset ≥ 20% → re-plan sekarang, jangan "kejar di fase berikutnya" (fase berikutnya sudah punya bebannya sendiri).
- Pilihan yang jujur, tawarkan eksplisit ke pemilik keputusan: kurangi scope (default terbaik) / geser tanggal / tambah orang (hampir selalu paling lambat efeknya - Brooks's law).
- Catat penyebab slip di dokumen timeline - pola slip adalah input estimasi proyek berikutnya.
Re-planning report format
Apa yang berubah · kenapa · dampak ke milestone & tanggal akhir · opsi + rekomendasi · keputusan yang dibutuhkan dan dari siapa, kapan.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
