Token cost

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.

Security

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 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.

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

  1. Read story.md for genre, themes, and tone context
  2. Read characters/_index.md for existing characters
  3. Ask for the character's name and role (protagonist, antagonist, supporting, minor)
  4. 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
  5. Write the character file using the template in references/character-template.md
  6. Save to characters/{name-kebab}.md
  7. Update characters/_index.md registry table
  8. If relationships reference existing characters, update those character files too

Updating a Character

  1. Read the existing character file
  2. Read characters/_index.md for context on other characters
  3. Make the requested changes
  4. If relationships changed, update the other character's file (bidirectional)
  5. Update characters/_index.md if 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:

Changes

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.
