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 | $0.00085 | $0.21306 |
| Opus 5 | $0.00043 | $0.10653 |
| Sonnet 5 | $0.00017 | $0.04261 |
| Haiku 4.5 | $0.00009 | $0.02131 |
Grade A, and why
narrative-building 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.

Purpose
Produce an elite-tier Strategic Narrative Document that constructs the story making a product, feature, or strategy feel inevitable — not by assertion but by structural argument. The output is not a tagline or a slide deck outline; it is a narrative engineering system: a structural spine, audience-adapted variants, evidence-integrated claims, pre-embedded objection responses, and a testing protocol that validates the narrative before it goes live.
When to Use / When NOT to Use
Use this skill when:
- Positioning a new product or repositioning an existing one in a competitive market
- Preparing a board deck, investor pitch, or executive strategy narrative
- Writing the "why now" story for a product launch or market entry
- Crafting the internal alignment narrative ("here's why we're doing this and not that")
- Building a launch narrative for press, analyst briefings, or customer communications
- Translating competitive analysis findings into a positioning story (downstream of Competitive Analysis)
- A product has strong fundamentals but the story isn't landing with stakeholders or customers
Do NOT use this skill when:
- You need competitive analysis (use Competitive & Market Analysis skill first — this skill consumes its output, it does not produce it)
- You need to define what to build (use Specification Writing skill — narrative follows strategy, not the other way around)
- You need customer discovery or research synthesis (use Discovery & Research skill — that's primary research, this is narrative construction from existing inputs)
- You need metric design or success measurement (use Metric Design & Experimentation skill)
- You need a tagline, slogan, or brand identity system (this skill produces strategic narrative, not copy)
Anti-inputs (what this skill does NOT handle):
- Customer interview synthesis (-> Discovery & Research skill)
- Competitive landscape mapping (-> Competitive & Market Analysis skill)
- Product specification (-> Specification Writing skill)
- Marketing copy, ad copy, or social media content (-> copywriting, not strategic narrative)
- Visual design for presentations (this produces the narrative structure; design is a separate discipline)
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.

narrative-building is a skill published in the GitHub repository Avyayalaya/agent-prime (8 stars, last pushed 3mo ago), licensed MIT. It adds 85 tokens to every session and 21,306 once invoked, about $0.0004 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.
