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 | $0.00060 | $0.00703 |
| Opus 5.5 | $0.00024 | $0.00281 |
| Sonnet 5.5 | $0.00012 | $0.00141 |
| Haiku 4.5 | $0.00006 | $0.00070 |
Grade A, and why
character-management 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.

Character Management
Overview
Create and manage rich character profiles for a story project. Each character is a markdown file with YAML frontmatter in the characters/ directory. Characters are cross-referenced with other story elements through kebab-case identifiers.
Prerequisites
A story project must already exist (created via the story-init skill). Verify by checking for story.md in the project root.
Creating a Character
- Read
story.mdfor genre, themes, and tone context - Read
characters/_index.mdfor existing characters - Ask for the character's name and role (protagonist, antagonist, supporting, minor)
- Build the profile through conversation, exploring:
- Appearance and distinguishing features
- Personality, traits, and quirks
- Backstory and formative events
- Motivations (external wants vs internal needs)
- Voice and speech patterns (ask for example dialogue)
- Character arc (starting state, turning points, ending state)
- Key life events for the timeline
- Write the character file using the template in
references/character-template.md - Save to
characters/{name-kebab}.md - Update
characters/_index.mdregistry table - If relationships reference existing characters, update those character files too
Updating a Character
- Read the existing character file
- Read
characters/_index.mdfor context on other characters - Make the requested changes
- If relationships changed, update the other character's file (bidirectional)
- Update
characters/_index.mdif role or status changed
Managing Relationships
Reference references/relationship-types.md for the full list of relationship types and inverse pairs.
When adding a relationship:
- Add the relationship entry to the character's frontmatter
- Add the inverse relationship to the other character's frontmatter
- Update the Relationship Map section in
characters/_index.md
Family Trees
Family trees are maintained in the characters/_index.md under the "Family Trees" section. Format:
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
