lorebook

A guidance loader for a quest template, where a quest is a structured coding task with defined phases. It reads the guidance for the current phase, such as research, planning, implementation, or review.

In plain words
What is it for?
Use it at the start of a quest phase when a template has been assigned, so the agent can load project or user guidance for that phase.
Why use it?
It brings the instructions relevant to the current phase into the work at the right time. This helps apply project-specific workflow advice without replacing the main task process.

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

lorebook 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 2d 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.

What it actually says

Lorebook — Quest Template Guidance

Load and apply phase-specific guidance from your assigned quest template.

When to Use

Invoke at the start of each quest phase when your spawn prompt includes a TEMPLATE: assignment.

Process

  1. Resolve the template file from two directories (highest priority first):

    • Project: .claude/fellowship-templates/{name}.md
    • User: ~/.claude/fellowship-templates/{name}.md

    Use the first match found. If no file exists, skip silently.

  2. Read the section matching your current quest phase:

    Phase Section
    Research ## Research Guidance
    Plan ## Plan Guidance
    Implement ## Implement Guidance
    Review ## Review Guidance
  3. Apply the guidance as advisory context for your current phase. Template guidance supplements but does not override the quest skill's phase requirements.

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.
