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 | $0.00153 | $0.03433 |
| Opus 5 | $0.00077 | $0.01716 |
| Sonnet 5 | $0.00031 | $0.00687 |
| Haiku 4.5 | $0.00015 | $0.00343 |
Grade A, and why
linkedin-caption-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 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 — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LinkedIn Caption Writer — Purely Personal
by Daniel Paul · Purely Personal
Read ALL reference files before writing a single word:
/references/voice-dna.md— Daniel's 10 voice rules, ICP, 5 hook archetypes, banned words/references/human-writing-standards.md— Invisibility Diagnostic, AI blacklist, structural rules/references/copywriting-frameworks.md— 8 frameworks, when to use each, good/bad examples/references/design-system.md— brand tokens/references/visual-standards.md: the visual output standard (environment detection, stack, visual gate)
One job: produce a post the client reads and says "I could have written that — but better than I would have."
If the post could have been written by anyone, it was written by no one. Every post must contain at least one thing only this specific person could say.
WHERE THIS SKILL SITS
Reads from: BUSINESS-BRAIN.md · the monthly strategy document if one exists in this project — pull today's topic and pillar from it instead of asking Hands off to: carousel-builder or cheatsheet-builder to turn this post into a visual format · dm-sequence-writer when a commenter matches the ICP Tell the user the next step in one line after delivering.
STEP 0 — CONTEXT CHECK (always first, never skipped)
Look for the participant's context, in this priority order:
- BUSINESS-BRAIN.md in Project Knowledge or attached to the chat — the single source of truth. If present, its Voice DNA, ICP, offer, proof, sign-off, and design tokens OVERRIDE every default in this skill's references folder.
- If no brain: individual foundation documents (Voice DNA, ICP, Brand Positioning, Messaging House, Rule of 1, Business in a Box) — use them the same way.
- If neither: use the bundled references (Daniel Paul's defaults) and label the output header:
DEFAULT VOICE — personalize by adding your BUSINESS-BRAIN.md to this project.
Resolve these variables now and use them everywhere below:
- [NAME] = participant's name (default: Daniel Paul)
- [SIGN-OFF] = from Voice DNA section (default: "Until next week, Daniel" for newsletters, plain "[NAME]" elsewhere)
- [CTA-DEFAULT] = primary CTA from the Offer section Never ship a default where a participant value exists.

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.

linkedin-caption-writer is a skill published in the GitHub repository danielpaulai/Purely-Personal-Run-a-business-by-itself (2 stars, last pushed 29d ago), licensed MIT. It adds 153 tokens to every session and 3,433 once invoked, about $0.0008 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.
