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.

What it costs to keep this loaded
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 | $0.00083 | $0.01713 |
| Opus 5 | $0.00042 | $0.00856 |
| Sonnet 5 | $0.00017 | $0.00343 |
| Haiku 4.5 | $0.00008 | $0.00171 |
Grade A, and why
s4h-writing-character-development 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing: Character Development
Flat characters come from describing traits rather than engineering contradictions. When a writer says "she's brave and determined," they have a label — not a person. Compelling characters feel real because they hold two things in tension simultaneously: they want something and need something different; they have a strength that doubles as a weakness; they act from a wound they can't fully see. These tensions generate unpredictable, specific behaviour that no list of adjectives could produce.
The key diagnostic is the want/need split. The want is what the character consciously pursues — their stated goal, their driving motivation as they'd describe it. The need is what would actually fulfil them — which is always different, often the opposite, and usually something they're avoiding. This gap between want and need is where character lives. It generates internal conflict, drives the arc, and makes every action simultaneously understandable and complicated.
Your Process
Step 1: State the Core Want vs. Core Need Name what the character consciously wants (their goal as they understand it) and what they actually need (what would genuinely fulfil or redeem them). These should differ — the want is typically external, visible, and achievable; the need is internal, invisible to the character, and requires change. If want and need are identical, the character has no arc.
Framing check: Confirm the specific character before continuing. State what you've identified — the character's name or role, the story context, and the central tension as you've read it — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the character and their situation]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different character or situation than read; incorporate the correction before proceeding
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.

s4h-writing-character-development is a skill published in the GitHub repository human-avatar/skills-for-humanity (223 stars, last pushed 1mo ago), licensed MIT. It adds 83 tokens to every session and 1,713 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 2026-09-03.
