Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.01215 |
| Opus 5 | $0.00015 | $0.00607 |
| Sonnet 5 | $0.00006 | $0.00243 |
| Haiku 4.5 | $0.00003 | $0.00121 |
Grade A, and why
break-complex-projects-into-milestones scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Break Complex Projects into Milestones (Work Breakdown Structure) (AI Skill)
Overview
Vague project plans ("Launch the new website by Q3") fail because they lack intermediate dependency mapping and concrete checkpoints. When you prompt an AI to plan a project without structure, it returns high-level motivational checklists rather than an operational project roadmap.
The Milestone Work Breakdown Structure (WBS) Protocol prompts the AI to act as a seasoned Technical Project Manager, constructing critical-path timelines, identifying blocker dependencies, and establishing strict Definition of Done (DoD) criteria for every phase.

Master WBS Prompt Templates
Pattern 1: The 4-Week Agile Sprint Roadmap
Use for technical launches, product releases, or marketing overhauls:
Act as a Senior Technical Project Manager.
Create a structured 4-Week Milestone Roadmap to [INSERT PROJECT GOAL] within a deadline of [TIMEFRAME / WEEKS].
For EACH week, provide:
1. **Weekly Theme & Primary Objective**: The single focus of that sprint.
2. **Key Deliverables**: 2-3 concrete artifacts (code, documents, assets) produced.
3. **Critical Dependencies & Blockers**: What must be completed before this week can start?
4. **Definition of Done (DoD)**: The exact verification test required to pass.
Format as clean, nested Markdown tables.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

break-complex-projects-into-milestones is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 1,215 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
