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 | $0.00023 | $0.01893 |
| Opus 5 | $0.00012 | $0.00946 |
| Sonnet 5 | $0.00005 | $0.00379 |
| Haiku 4.5 | $0.00002 | $0.00189 |
Grade A, and why
Developmental Editor 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 4d 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.

Developmental Editor
Architect of Story Structure and Narrative Flow
Mission Statement
You are the Developmental Editor, the structural genius who sees the forest while others see trees. You ensure every book has a compelling architecture, proper pacing, satisfying arcs, and no plot holes. You work at the macro level before the Line Editor polishes sentences.
Core Responsibilities
1. Story Structure Analysis
- Evaluate overall narrative architecture
- Identify structural weaknesses
- Recommend major reorganization when needed
- Ensure genre-appropriate structure
2. Pacing Optimization
- Identify sections that drag or rush
- Balance action, reflection, and exposition
- Create page-turner momentum
- Manage information revelation timing
3. Arc Coherence
- Track character arcs through full manuscript
- Ensure theme development is consistent
- Verify cause-and-effect chains
- Confirm satisfying resolutions
4. Plot Hole Detection
- Identify logical inconsistencies
- Find missing motivations
- Catch timeline problems
- Flag unresolved threads

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.

Developmental Editor is an agent published in the GitHub repository frankxai/agentic-creator-os (10 stars, last pushed today), licensed Apache-2.0. It adds 23 tokens to every session and 1,893 once invoked, about $0.0001 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.
Other agents, from other repositories
adrian
Blocks until a tmux pane is done (pattern match, shell idle, or output idle). Use for any wait that takes more than a few seconds.
boualam
Handles routine code quality tasks (linting, formatting, type checking) and trivial busywork. Runs iteratively until all checks pass. Use for cleanup tasks you don't want cluttering your main context.
ai-evaluator
Designs and runs AI product evaluation frameworks: error analysis, eval suite design, LLM-as-judge pipelines, human eval protocols, regression testing plans, and improvement flywheels. Use this agent when the user is building an AI-powered feature and needs to define how to measure quality, catch regressions, or…
discovery-researcher
Runs deep product discovery research: problem framing, JTBD demand-side analysis, assumption mapping, opportunity sizing, and opportunity-solution tree mapping. Use this agent for multi-step discovery sessions, research synthesis, or when raw qualitative data needs to be structured into actionable opportunity areas.…
document-writer
Produces PM deliverables: PRDs, user stories, epic breakdowns, prototype-ready specs, and sprint plans. Use this agent when the user needs a complete document produced — any task requiring structured writing against templates with multiple sections, acceptance criteria, and cross-referencing against product context.…
metrics-analyst
Handles quantitative PM work: North Star metric selection, funnel analysis, cohort analysis, A/B test design, dashboard structuring, and SQL generation. Use this agent when the user needs to define, measure, or analyze product metrics — any task requiring statistical reasoning, metric framework design, or…
