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 | $0.00114 | $0.01352 |
| Opus 5 | $0.00057 | $0.00676 |
| Sonnet 5 | $0.00023 | $0.00270 |
| Haiku 4.5 | $0.00011 | $0.00135 |
Grade A, and why
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 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Case Study Writer
Write a decision story, not a process diary. Show what changed in the team's understanding, what the author specifically contributed, why key choices were made, and what evidence supports the result.
1. Define audience and format
Identify:
- target role, seniority, company type, and reviewer needs;
- format: portfolio page, interview deck, PDF, application excerpt, or verbal walkthrough;
- expected reading time and confidentiality constraints;
- competencies the project can genuinely demonstrate.
Optimize the same evidence differently for a recruiter scan, hiring-manager review, craft critique, and cross-functional interview. Do not make one page carry every detail.
2. Build an evidence ledger
Read references/evidence-and-claims.md. Extract only what is supported:
Claim | Evidence | Source | Author's role | Confidence | Confidentiality | Visual candidate
Separate:
- direct contribution from team contribution;
- observed user evidence from stakeholder opinion;
- shipped outcome from prototype result;
- measured result from directional signal;
- fact from interpretation and retrospective learning.
Ask for missing material when it changes credibility. If it remains unavailable, write around the gap transparently.
Checkpoint: Before shaping the story, verify that the pivotal decision and headline outcome each map to evidence or an explicit limitation. After drafting, re-check every claim against the ledger; downgrade, qualify, or remove unsupported claims, then repeat until every retained claim is supported or visibly limited.
3. Find the narrative spine
Use:
Context -> Tension -> Evidence -> Decision -> Change -> Outcome -> Learning
The tension should be a real conflict or uncertainty: competing user goals, technical limits, harmful existing behavior, ambiguous data, organizational constraint, or a failed first approach. The decision must show judgment, not merely sequence.
Draft one sentence:
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

case-study-writer is a skill published in the GitHub repository aditya-ariosity/ux-ui-skills (2 stars, last pushed 2d ago), licensed MIT. It adds 114 tokens to every session and 1,352 once invoked, about $0.0006 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 2026-09-04.
