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 | $0.00029 | $0.00389 |
| Opus 5.5 | $0.00012 | $0.00156 |
| Sonnet 5.5 | $0.00006 | $0.00078 |
| Haiku 4.5 | $0.00003 | $0.00039 |
Grade A, and why
writer-characters 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 28d 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.
What it actually says
Characters and dialogue
When to use
Use for cast design, unclear motivation, relationship progression, dialogue differentiation, or testing a character's response to pressure.
Inputs and assumptions
Read existing appearances and knowledge state. Ask what role this character serves and which facts are fixed.
Portable workflow
- Define a concrete desire, a feared cost, a self-protective habit, and a contradiction that can produce choices.
- Give relationships different tensions. A character may be generous with a sibling and guarded with a teacher without being inconsistent.
- Establish what the character knows at this point. Do not grant access to narrator-only or future information.
- Design voice through register, rhythm, evasions, favored subjects, and subtext. Avoid catchphrases as the sole identifier.
- Test the character in a short exchange or difficult choice. Label in-character improvisation as exploration, not a manuscript event.
- Propose an arc as pressure, choice, and consequence rather than a list of personality adjectives.
- Save approved facts and proposed changes separately using the project workflow.
Safety and side effects
Preserve established identities and motives unless the author approves a retcon. Do not turn a simulated interview into canon automatically.
Scripts, references, and dependencies
No external dependencies. Style choices can help separate narrative voice from dialogue voice.
Verification
Check whether two speakers remain distinguishable without dialogue tags, whether decisions follow from their current incentives, and whether each knows only what the story permits.
Pi adapter
Use /writer characters --brief "Give the rival a credible reason to help, without making him secretly benevolent".
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.

writer-characters is a skill published in the GitHub repository Firstp1ck/pi-coding-agent-forge (91 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 389 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-19.
