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 | $0.00078 | $0.00486 |
| Opus 5 | $0.00039 | $0.00243 |
| Sonnet 5 | $0.00016 | $0.00097 |
| Haiku 4.5 | $0.00008 | $0.00049 |
Grade A, and why
jobs-to-be-done 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 8d 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.
This is a copy
100% identical to jobs-to-be-done — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Domain Context
This skill implements a proven product management framework. The approach combines best practices from industry leaders and is designed for practical application in day-to-day PM work.
Input Requirements
- Context about your product, feature, or problem
- Relevant data, research, or constraints (recommended but optional)
- Clear articulation of what you're trying to achieve
Jobs-to-be-Done (JTBD)
What It Is
Jobs-to-be-Done is a framework for understanding customer motivation. The core insight: people don't buy products, they hire them to make progress in their lives.
When someone buys a product, they're not buying features or benefits—they're hiring that product to do a job. Understanding that job unlocks everything: positioning, messaging, feature prioritization, and competitive strategy.
The key shift: Move from asking "What do customers want?" to asking "What progress are customers trying to make?"
When to Use It
Use JTBD when you need to:
- Understand why customers buy (not just what they buy)
- Discover your true competitive set (often not who you think)
- Find product-market fit for a new product or feature
- Improve positioning and messaging that resonates
- Reduce churn by understanding why customers leave
- Prioritize your roadmap based on real customer progress
- Identify new market opportunities through struggling moments
When Not to Use It
- There's no real customer choice (e.g., employer-mandated software)
- The purchase is pure habit with no conscious decision
- You want to validate a hypothesis you've already decided on

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.

jobs-to-be-done is a skill published in the GitHub repository saski/arnesto (5 stars, last pushed yesterday), licensed Unlicense. It adds 78 tokens to every session and 486 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to jobs-to-be-done, differing in 0 lines, and is treated as a copy.
