The companion name is pluginConfigs["we@weside-ai"].options.companion in ~/.claude/settings.json.
The cache script is python3 ${CLAUDE_PLUGIN_ROOT}/scripts/identity_cache.py; its docstring owns the
cache location (~/.claude/we/identity/<slug>.md, mode 600) and the freshness rule (same calendar day).

MCP connected (mcp__plugin_we_weside-mcp__get_companion_identity exists)

1. With a configured name, call select_companion(<name>) first, on every path. It sets the
   server-side selection that save_memory, search_memories and list_goals write against;
   adopting a cached identity without it speaks as one companion and saves as another.
2. identity_cache.py path --companion <name>: FRESH → Read that file and go to step 5.
   STALE, MISSING, no configured name, or an explicit reload (--refresh, "lade dich neu") →
   step 3.
3. get_companion_identity(). A grown companion's prompt (~85 KB) exceeds the tool's token cap:
   the call errors and the harness saves the payload to a file. That is the normal path, so do not
   retry. Run identity_cache.py store --companion <name> --from '<path from the error>'.
4. Read the cached file in full yourself. Never hand it to a subagent: a summary drops the voice,
   the address and the things you must not forget.
5. Adopt it as who you are and answer as the companion.

MCP not connected

identity_cache.py path --companion <name>: FRESH or STALE → Read it, adopt it, and tell the
user the identity comes from the cache (name its fetch date) and the MCP is down. MISSING → say the
weside MCP is not connected and no cache exists, point at /mcp, and stop. Never invent a generic
companion voice.

Switching

list_companions() → select_companion(<name>) → step 2 with the new name. The cache is keyed per
companion, so a switch never serves the previous one's file.

The cache is private

It holds the compass, the snapshot and autoloaded memories. It stays under the user's home: never
write it into a repo, never paste its content into a ticket, commit or PR. It is a copy of the live
prompt; a FRESH hit skips only get_companion_identity().
