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 | $0.00083 | $0.05125 |
| Opus 5 | $0.00042 | $0.02563 |
| Sonnet 5 | $0.00017 | $0.01025 |
| Haiku 4.5 | $0.00008 | $0.00513 |
Grade A, and why
shape-up 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 9d ago.
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 — 811 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shape Up
Escape the build trap and endless backlogs. Use Basecamp's methodology to ship meaningful work in 6-week cycles with fixed time, variable scope.
When to Use This Skill
- Product planning to replace endless backlogs
- Feature development with clear time boundaries
- Team autonomy when you want self-directed teams
- Scope management when projects tend to balloon
- Startup development with limited resources
- Agency/consulting projects with fixed timelines
Methodology Foundation
| Aspect | Details |
|---|---|
| Source | Ryan Singer - Shape Up (2019), developed at Basecamp |
| Core Principle | "Fixed time, variable scope. Appetite, not estimates. Shape before you build." |
| Why This Matters | Traditional methods either micromanage (waterfall) or leave too much open (agile sprints without direction). Shape Up gives teams direction AND autonomy. |
What Claude Does vs What You Decide
| Claude Does | You Decide |
|---|---|
| Structures production workflow | Final creative direction |
| Suggests technical approaches | Equipment and tool choices |
| Creates templates and checklists | Quality standards |
| Identifies best practices | Brand/voice decisions |
| Generates script outlines | Final script approval |
What This Skill Does
- Introduces shaping - Defining work at the right level of abstraction
- Sets appetites over estimates - How much time is this worth?
- Enables cycles - 6-week focused work, 2-week cooldown
- Empowers teams - Autonomy within boundaries
- Provides betting tables - Principled prioritization
- Manages scope dynamically - Must-haves vs. nice-to-haves

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.

shape-up is a skill published in the GitHub repository guia-matthieu/clawfu-skills (149 stars, last pushed 5mo ago), licensed MIT. It adds 83 tokens to every session and 5,125 once invoked, about $0.0004 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 2026-09-03.
