Log Cannon

Extract significant narrative events from a session and append them to the campaign's canon timeline.

Step 1: Discover the Campaign

Follow the campaign discovery convention from the omen domain CLAUDE.md.

Step 2: Identify the Session Log

$ARGUMENTS may contain:

• A path or wikilink to a session log file
• A session number -- find the matching file in logs/
• Nothing -- list recent sessions and ask which one to process

Read the session log file in full.

Step 3: Read Existing Canon

Read lore/_cannon.md to understand:

• The current timeline and latest entries
• Existing wikilinks and naming conventions used in this campaign
• What's already been logged (avoid duplicates)

Step 4: Read Existing Indexes

Scan lore/_npcs.md and lore/_places.md to know which NPCs and places already have entries. This ensures wikilinks point to known names and use established aliases.

Step 5: Extract Canon Events

Analyse the session log for events that are narratively significant -- moments that change the state of the world, alter relationships, reveal secrets, or create consequences. Not every action is canon.

Signals of canon weight:

• Decisions that close off alternatives (Fork/Climax game types are inherently canon-heavy)
• Reveals -- information the players or characters didn't have before
• Relationship shifts -- alliances formed, betrayals, deaths, new enemies
• World-state changes -- locations destroyed, factions moved, power shifts
• Character milestones -- goals achieved, trauma, transformation

For each event, draft a terse dot-point entry:

• Use [[wikilinks]] for every NPC, place, organisation, or concept that has or should have a lore entry
• Keep entries factual and chronological
• Write from an omniscient narrator perspective, not a player perspective
• One line per event -- dense but readable

Step 6: Present for Review

Show the extracted events to the user before writing:

Canon from {session} -- {N} events extracted:

• event 1
• event 2
• ...

Add all, edit, or drop any?

Step 7: Append to Canon

Add the approved events to lore/_cannon.md under a heading for this session:

### {Session Reference} -- {Date}
- event 1
- event 2

Append after the last existing session block.

Step 8: Confirm

Canon updated. {N} events from {session} added to {campaign} timeline.
