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 | $0.00212 | $0.02759 |
| Opus 5 | $0.00106 | $0.01380 |
| Sonnet 5 | $0.00042 | $0.00552 |
| Haiku 4.5 | $0.00021 | $0.00276 |
Grade A, and why
b2b-case-study-writer 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.

B2B Case Study Writer: Proof That Works in a Sales Conversation
This skill writes B2B case studies that function as sales assets, not content marketing decoration. The difference matters. Most case studies fail as sales tools because they are written to satisfy the content calendar rather than to answer the question a prospect has at the moment a deal is at risk.
A case study earns its place in a sales conversation when it answers a specific objection, demonstrates a specific outcome that the prospect cares about, and uses a customer voice that is credible to the reader. A case study that is too long, too vague, or too focused on the vendor's process rather than the customer's outcome does not move deals forward.
This skill also covers the decisions that most practitioners get wrong: which result to lead with, how to get customer approval on specific numbers, how to write a case study when the customer will not approve quantified results, and how to repurpose one case study across formats without reproducing it from scratch.
HOW TO SET UP THIS SKILL
Provide:
- The customer or client and what they do (anonymized if required)
- The problem they had before engaging with the program or product
- What you or the product did specifically
- The measurable results with numbers where available
- Any direct quotes from the customer or key contact
- Where the case study will be used: website, sales outreach, proposal, presentation, or all of the above
- Whether customer approval is required and whether numbers can be attributed by name
If results are not yet confirmed or approved, the skill will help structure the interview and approval process before writing.
The Strategic Decisions Before Writing
Decision 1: Which result to lead with
Most case studies lead with the result the company is most proud of. The right case study leads with the result the prospect cares most about at the moment they are reading it.
These are different things. A company might be proud of a 10x organic traffic increase. A prospect evaluating a demand gen program cares about pipeline and revenue attribution. Leading with traffic when the prospect needs revenue proof loses the case study before the second paragraph.
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.

b2b-case-study-writer is a skill published in the GitHub repository matellez/claude-skills (4 stars, last pushed 5mo ago), licensed MIT. It adds 212 tokens to every session and 2,759 once invoked, about $0.0011 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.
