Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00041 | $0.02594 |
| Opus 5 | $0.00020 | $0.01297 |
| Sonnet 5 | $0.00008 | $0.00519 |
| Haiku 4.5 | $0.00004 | $0.00259 |
Grade A, and why
ajtbd-methodology 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.

Advanced Jobs To Be Done Methodology
This skill provides you with deep knowledge of the Advanced JTBD methodology for product development, market analysis, and customer segmentation.
When to Use This Skill
Automatically invoke this skill when the user:
- Asks about product-market fit
- Needs help with customer segmentation
- Wants to analyze market opportunities
- Is launching a new product
- Needs to validate product assumptions
- Asks about customer jobs, needs, or motivations
- Wants to create value propositions or landing pages
- Discusses product strategy or growth
Core AJTBD Principles
1. Jobs Are Primary
Job (Work) = A goal a person wants to achieve to satisfy their psychological need. Always occurs in a specific situation with a desired result.
Formula:
When:
- Context: {situation}
- Past experience/knowledge: {what they know}
- Personal characteristics: {traits affecting the job}
- Negative emotions: {what they feel now}
- Trigger: {what activated this job}
Want: {expected result}
- Success criteria: {how they'll evaluate success}
So that: {higher-level job result}
- And: {feel differently after achieving the result}
2. Job Hierarchy
- Big Job - Higher-level work that provides context for Core Job, but product doesn't fully complete it
- Core Job - The highest-level job the product completes fully. What customer actually pays for.
- Small Jobs - Jobs below Big Job level. Core Job is part of Small Jobs.
- Micro Jobs - Low-level tasks, often "necessary evil" (e.g., "fill in form", "click button")
3. Solutions Are Replaceable, Jobs Are Not
- Products compete to be "hired" for a job
- Customer hires the solution that best completes the job by combined factors
- Consideration Set - All solutions the person knows that can complete the job
- Switching happens only when new solution wins in the Consideration Set
4. Segmentation by Jobs
Real segmentation answers three questions:
- Can we create additional value knowing this segmentation?
- Can we achieve target profit per unit in this segment?
- Can we scale and create demand in this segment?
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.

ajtbd-methodology is a skill published in the GitHub repository catch-the-wave/fullstack-ios-claude-skills (5 stars, last pushed 8mo ago), licensed MIT. It adds 41 tokens to every session and 2,594 once invoked, about $0.0002 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 2026-08-31.
