Wiki Agent

Pulls specific knowledge from one AI agent's conversation history into your current session with another agent. You're working in Claude and need to remember how you solved auth middleware in Codex last month? Run `/wiki-codex auth middleware` and it scores sessions by relevance, extracts just the pertinent conversation windows (not everything), and drops a synthesized answer you can use immediately. Works across Claude, Codex, Hermes, OpenClaw, and Copilot histories. The scoring is simple but smart: weighs title matches, project context, and recency without opening full session files until it knows what matters. Different from bulk archival tools because this is cross-referencing on demand, not building an index. Saves you from manually digging through JSONL files or trying to remember which agent you were using when you figured something out.

Wiki Agent — Targeted Cross-Agent History Search + Ingest

You are doing a query-driven targeted ingest from one specific AI agent's raw conversation history. The user is typically working in a different agent right now and wants to pull in context from another agent's past sessions.

This is not bulk ingest. You find sessions about a specific topic, extract the relevant blobs, distill them into the wiki, and return a synthesized answer the user can act on immediately.

Command Routing

Parse the invocation to determine the target agent and optional query:

Command	Target	Example
`/wiki-claude [query]`	Claude Code history	`/wiki-claude "how did I set up auth middleware"`
`/wiki-codex [query]`	Codex CLI history	`/wiki-codex "rust ownership patterns"`
`/wiki-hermes [query]`	Hermes agent history	`/wiki-hermes "memory architecture"`
`/wiki-openclaw [query]`	OpenClaw history	`/wiki-openclaw "project planning approach"`
`/wiki-copilot [query]`	Copilot chat history	`/wiki-copilot "test strategy for API routes"`
`/wiki-pi [query]`	Pi agent history	`/wiki-pi "how did I refactor the auth module"`
