Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00091 | $0.01983 |
| Opus 5 | $0.00046 | $0.00992 |
| Sonnet 5 | $0.00018 | $0.00397 |
| Haiku 4.5 | $0.00009 | $0.00198 |
Grade A, and why
pyramid-long-form 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 12d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pyramid Long-Form
Purpose
Structure or draft a multi-section professional document. Load pyramid-principle-core for structure and direct language. Add a pyramid-source-integrity check when facts or data materially affect the output; receive a claim packet only when strict trace mode applies.
This skill handles documents that require developed sections or usually exceed about 500 words. It does not audit existing writing or produce slide storylines.
Route the Request
Use this skill for reports, briefs, proposals, research writeups, decision documents, strategy documents, and whitepapers.
Hand off when:
- the artifact is an email, Slack update, executive summary, or one-pager →
pyramid-short-form - the artifact is a deck or presentation storyline →
pyramid-presentation - the user wants existing writing diagnosed →
pyramid-audit - the user wants the framework explained →
pyramid-principle-core
Identify the Inputs
Before structuring the document, the agent identifies:
- Reader question: What must the document answer?
- Governing thought: Which decision, recommendation, or finding did the user supply?
- Cleared claims: When source integrity applies, which facts, calculations, inferences, recommendations, and limitations may the document use, and what source, locator, confidence, and reason accompany each data point?
- Requested depth: Outline, detailed outline, section draft, or full document?
- Constraints: Audience, length, tone, required sections, sensitivity, and citation format.
The agent asks a question only when a missing answer would materially change the document and the supplied evidence does not support a safe choice.
Return the Requested Depth
- Outline: Return the title, actual decision or governing claim, section claims, and nested source-backed supports. The eventual document word budget does not set the outline's length. Do not draft body prose or output framework commentary.
- Detailed outline: Add subsection claims, evidence placement, and source notes.
- Section draft: Draft only the requested section and preserve its position in the document logic.
- Full document: Draft the complete document after the outline passes the internal checks.
What ships with it
2 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.

pyramid-long-form is a skill published in the GitHub repository tyroneross/pyramid-principle (28 stars, last pushed 5d ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,983 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 2026-08-30.
