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 | $0.00162 | $0.08191 |
| Opus 5.5 | $0.00065 | $0.03276 |
| Sonnet 5.5 | $0.00032 | $0.01638 |
| Haiku 4.5 | $0.00016 | $0.00819 |
Grade A, and why
scene-inventory-extractor 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 2mo 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.

Scene Inventory Extractor
Systematic workflow for extracting comprehensive scene inventories from narrative source material and preparing every visual asset required for AI video generation. Continuity is a first-class deliverable: extract story-state, dressing-state, and object-state before writing prompts so a crew can reset scenes accurately when production shoots out of order.
Execution Context
This skill is designed for a command-line agent with:
- nanobanana image generation MCP (
generate_image,edit_image,character_consistency, andmulti_image_fusionas needed), with every image call explicitly usingmodel: gemini-3-pro-image-preview - Vision capabilities (ability to inspect generated images for consistency)
- File system access (structured output directories)
All image generation and verification runs silently — no user confirmation gates
during generation phases. Halt only on consistency failures that require human judgement.
If gemini-3-pro-image-preview is unavailable through the nanobanana MCP, or if it
cannot accept the reference images or character-consistency images required by the
current phase, STOP and report the blocker. Do not switch to another image model.
Workflow Overview
| Phase | Name | Output |
|---|---|---|
| 1 | Source Analysis | Annotated reading notes |
| 2 | Creative Pillars | Visual aesthetic + storytelling style + cinematography specification + prompt keyword library |
| 3 | Narrative Spine | Structure, themes, turnpoints |
| 4 | Character Bible | Character entries with reference-image specifications |
| 5 | Locations Bible | Location entries with multi-angle, multi-condition scouting specs |
| 6 | Props Bible | Props with physical descriptions and ref-image specs |
| 7 | Scene Inventory | Per-scene breakdowns |
| 8 | Continuity Inventory | Character/location/prop state tracking across scenes |
| 9 | Shot Lists | Shot tables with full cinematography fields and duration budgets |
| 10 | Thematic Image Plan | Key narrative-beat images |
| 11 | Reference Image Generation | All character, location, and prop reference images with video role manifest |
| 12 | Shot-Frame Generation | Start frame, end frame, and key frames per shot |
| 13 | Consistency Verification + Handoff | Vision-based QA pass; final scene pack, frame assets, role manifest, and handoff notes for shot-specifier |

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.

scene-inventory-extractor is a skill published in the GitHub repository leynos/visual-storytelling-skills (9 stars, last pushed 28d ago), licensed ISC. It adds 162 tokens to every session and 8,191 once invoked, about $0.0006 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 2026-08-31.
