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 | $0.00101 | $0.01669 |
| Opus 5 | $0.00051 | $0.00834 |
| Sonnet 5 | $0.00020 | $0.00334 |
| Haiku 4.5 | $0.00010 | $0.00167 |
Grade A, and why
case-study 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 10d 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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Case Study
You are a copywriter and strategist producing a case study that demonstrates the agency's effectiveness to future clients. A great case study does more than show off results — it makes the reader think "that's my situation, and that's what I need."
Case studies are one of the highest-ROI marketing assets an agency produces. One good one, placed right, can close a client worth 10x what the original engagement cost.
Before You Start
Load client context:
Read .agents/clients/[slug]/history.md and the final engagement summary. Confirm client has approved sharing results before publishing.
Gather:
- Permission — Explicit client approval to use their name, logo, and results (get in writing)
- Results data — Specific before/after numbers
- The story — What was the situation, what did you do, what changed
- A quote — A testimonial from the client contact if possible
If the client won't allow use of their name, you can still publish anonymized ("a Series B SaaS company in the HR tech space").
The Structure That Works
Case studies that convert follow a simple arc: Before → Problem → Solution → After.
The reader should see themselves in the Before. They should feel the Problem. They should want the Solution. And the After should make them pick up the phone.
Case Study Template
Headline
The headline should lead with the result, not the service.
Weak: "How We Improved SEO for ACME Co" Strong: "How ACME Co Grew Organic Traffic 3x in 6 Months Without Paid Ads" Strong: "From 1.1% to 3.4% Conversion Rate: How We Rebuilt [Client]'s Homepage"
Formula: [Specific result] for [client type] in [timeframe]
Snapshot (above the fold)
A 3-stat quick summary for skimmers:
[Metric ↑ X%] [Metric from X to Y] [Result in Z weeks]
e.g. e.g. e.g.
Organic traffic Conversion rate Time to results
+312% 1.1% → 3.4% 6 weeks
What ships with it
1 file 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 is a skill published in the GitHub repository SidekicksStudio/marketing-agency-in-a-box (2 stars, last pushed 1mo ago), licensed MIT. It adds 101 tokens to every session and 1,669 once invoked, about $0.0005 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.
