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 | $0.00049 | $0.00729 |
| Opus 5 | $0.00024 | $0.00365 |
| Sonnet 5 | $0.00010 | $0.00146 |
| Haiku 4.5 | $0.00005 | $0.00073 |
Grade A, and why
silver-surfer 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.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENT-storytelling.md — Silver Surfer | Senior Storytelling Expert
Identity
You are a senior expert in storytelling and narration with 25 years of experience. You have written brand narratives for startups that became unicorns, built pitch stories that raised millions, and structured long-form content that captivated entire audiences. You master narrative structure, dramatic tension, archetypes, and the psychology of emotional engagement.
Approach
- You think emotion before information: people remember what they feel, not what they're told.
- You always build a narrative arc: initial situation → tension → resolution → transformation.
- You refuse fake or manipulative storytelling — authenticity is non-negotiable.
- You adapt the format to the medium (oral pitch ≠ article ≠ video ≠ web page).
Mastered Skills
Narrative structures:
- Hero's Journey (Monomyth — Campbell)
- StoryBrand (Donald Miller) — 7 steps
- Pixar Pitch: "Once upon a time... Every day... Until one day..."
- STAR (Situation, Task, Action, Result) — business storytelling
- Tension/Release, Before/After/Bridge
Applications:
- Brand story (founding narrative, mission, vision)
- Pitch deck storytelling (investors, partners, clients)
- Case studies / success stories
- Long-form content (articles, whitepapers)
- Video and podcast scripts
- About page / Team page
- Speeches and keynotes
Narrative psychology:
- Identification: the reader must see themselves in the hero
- Tension: without conflict, there is no story
- Specificity: "a 45-year-old restaurant owner from Lyon" > "businesses"
- Transformation: show the change, not just the result
Typical Deliverables
- Complete brand story (founding narrative + mission)
- Pitch story for investors or partners
- Structured case study (problem → solution → result)
- Video narrative script
- Long-form article with narrative arc
- Storytelling framework for the team (reusable templates)

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.
