For efficient searching of large SRD files, use grep with the following patterns.
Searching Spells (07_Spells.md)
Spells are organized under #### Spell Name headings. Use case-insensitive search:
# Find a specific spell (show 40 lines for full description)
grep -i -A 40 "^#### Fireball""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/07_Spells.md"# Find a specific spell by partial name
grep -i -A 40 "^#### .*Lightning""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/07_Spells.md"# List all spells starting with a letter
grep "^#### ""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/07_Spells.md" | grep -i "^#### A"# Search spell descriptions for keywords (e.g., concentration spells)
grep -i -B 2 "Concentration""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/07_Spells.md" | grep -i "^####"
Searching Monsters (12_MonstersA-Z.md)
Monsters are organized under ## Monster Name headings:
# Find a specific monster (show 60 lines for full stat block)
grep -i -A 60 "^## Adult Red Dragon""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/12_MonstersA-Z.md"# Find monsters by partial name
grep -i -A 60 "^## .*Zombie""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/12_MonstersA-Z.md"# List all monsters
grep "^## ""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/12_MonstersA-Z.md"# Find monsters by CR (search for "CR X" pattern in stat blocks)
grep -B 10 "CR 5""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/12_MonstersA-Z.md" | grep "^##"
Searching Magic Items (10_MagicItems.md)
Magic items use #### Item Name headings:
# Find a specific magic item
grep -i -A 30 "^#### Bag of Holding""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/10_MagicItems.md"# Find all items of a rarity
grep -i -B 2 "Rare""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/10_MagicItems.md" | grep "^####"
Searching Rules Glossary (08_RulesGlossary.md)
Rules definitions use #### Term headings:
# Find a specific rule definition
grep -i -A 15 "^#### Advantage""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/08_RulesGlossary.md"# Find rules mentioning a condition
grep -i -A 15 "^#### Frightened""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/08_RulesGlossary.md"# List all rule definitions
grep "^#### ""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/08_RulesGlossary.md"
Searching Classes (03_Classes/)
Each class has its own file:
# Find class features
grep -i -A 20 "^## ""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/03_Classes/05_Fighter.md"# Search all classes for a feature name
grep -ri "Extra Attack""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/03_Classes/"

# Find weapon properties
grep -i -A 5 "^#### Heavy""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/06_Equipment.md"# Find armor stats
grep -i -A 10 "^#### Chain Mail""${CLAUDE_PLUGIN_ROOT}/skills/d20-rules/references/srd/06_Equipment.md"
Response Format
When answering rule questions:
Quote the exact SRD text first (use blockquotes)
Cite the source file
Explain or clarify if needed
Note any related rules
Example response:
From 08_RulesGlossary.md:
Advantage
If you have Advantage on a D20 Test, roll two d20s, and use the higher roll. A roll can't be affected by more than one Advantage, and Advantage and Disadvantage on the same roll cancel each other.
This means having multiple sources of Advantage doesn't stack - you still only roll two dice.
Attribution Requirement
When quoting substantial portions of the SRD in any output, include the CC-BY-4.0 attribution from 00_Legal.md:
