Gladiator Plugin

Continuous learning. Observes tool failures and prompts reflection at session end to evolve rules, hooks, and skills.

Hooks

Hook	When	Action
PostToolUse(Bash|Edit|Write)	After tool failure	Observes the error pattern (silent on success)
Stop	Session ending	Prompts reflection if unprocessed observations exist

Commands

Command	Description
/review-gladiator [topic]	Batch learn from accumulated observations and session history

Workflows

Observe (automatic via hooks)

Tool failures trigger observation automatically:

gladiator_observe(
  summary: "<what failed and how it was fixed>",
  context: {error, tool, before, after},
  tags: ["error", "<tool_name>"]
)

Reflect (standalone)

1. gladiator_reflect() — cluster observations into recommendations
2. For each recommendation: read the existing artifact (if overlap detected)
3. Propose UPDATE to existing artifact, not a new duplicate
4. Present to user with reasoning
5. Apply changes one at a time after approval

Reflect (with siblings)

1. If historian active: enrich reflection with broader context
   • search_conversations("project or topic") — related past work
   • get_error_solutions("specific error") — for error clusters
   • find_tool_patterns("tool name") — for tool workflow clusters
2. gladiator_reflect() — cluster observations
3. If oracle active: for each recommendation involving new artifacts
   • search("cluster tag") — check if best-in-class solution already exists
   • Install existing solution instead of reinventing
4. Present enriched recommendations: pattern + history + available tools
5. Apply changes one at a time after approval

Batch Review (/review-gladiator)

1. If historian active: list_recent_sessions() to get session refs
2. gladiator_observe(source: "conversation", session_ref: <ref>) for relevant sessions
3. gladiator_reflect() to cluster all observations
4. If oracle active: search for existing solutions before creating new
5. Present recommendations to user

Sibling Synergy

Sibling	Value	How
Historian	Past solutions enrich reflection	get_error_solutions(), search_conversations(), find_tool_patterns()
Oracle	Existing tools found before creating new	Search oracle for best-in-class solutions during reflection
Praetorian	n/a	Gladiator has its own persistence
Vigil	n/a	Different concerns (files vs patterns)

Observation Templates

Situation	Call
Tool failure (auto)	gladiator_observe(summary, context={error, tool, before, after}, tags=["error", tool])
User correction	gladiator_observe(summary, context={before, after}, tags=["correction"])
Convention found	gladiator_observe(summary, tags=["convention", "domain"])
Decision made	gladiator_observe(summary, tags=["architecture", "decision"])
