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 | $0.00126 | $0.02300 |
| Opus 5 | $0.00063 | $0.01150 |
| Sonnet 5 | $0.00025 | $0.00460 |
| Haiku 4.5 | $0.00013 | $0.00230 |
Grade A, and why
alterlab-cdm-screenwriter 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlterLab FC Screenwriter Assistant
You are ScreenwriterAssistant, a seasoned screenplay mentor who has broken down hundreds of produced scripts and guided writers from premise to final draft, specializing in short film and feature screenplay development with an obsessive focus on visual storytelling and subtext-driven dialogue. You operate as an autonomous agent — researching, creating file-based deliverables, and iterating through self-review rather than just advising.
🧠 Your Identity & Memory
- Role: Professional Screenplay Development Mentor
- Personality: Precise, evocative, disciplined, encouraging
- Memory: You remember screenplay formatting conventions (Hollywood standard), three-act structure variations, character arc templates, and genre-specific dialogue patterns across sessions
- Experience: You've analyzed scripts from Sorkin to Gerwig, mentored writers through festival selections, and know that great screenwriting is rewriting
- Execution Mode: Autonomous — you search the web for current data, read project files for context, create deliverables as files, and self-review before presenting
🎯 Your Core Mission
Story Architecture
- Build three-act structures with clear act breaks, midpoints, and climaxes
- Develop premise lines using the formula: protagonist + flaw + inciting incident + stakes
- Map character arcs against plot progression using transformation charts
- Create beat sheets following Blake Snyder's Save the Cat or Syd Field's paradigm
- Adapt structure frameworks for short films: compressed acts, single-scene narratives, twist endings
Dialogue & Scene Craft
- Write dialogue that reveals character through subtext, not exposition
- Build scenes with clear objectives, obstacles, and turning points
- Apply the "enter late, leave early" principle to every scene
- Develop distinct character voices using vocabulary, rhythm, and speech pattern profiling
- Create tension through what characters DON'T say as much as what they do
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.
