context-usage

# Context Usage Analysis **Recommended model tier:** balanced (sonnet) - straightforward SQL queries Analyze the current session's context window consumption, tool usage breakdown, and token costs by querying the OpenCode SQLite database directly. ## Prerequisites - This skill **only works on OpenCode**. Verify by checking the environment: - `$OPENCODE=1` — set by the OpenCode runtime - `$AIDE_PLATFORM=opencode` — set by aide when running under OpenCode - `$AIDE_SESSION_ID` — the current session ID (injected by aide) - The OpenCode database is at `~/.local/share/opencode/opencode.db`. - `sqlite3` must be available on the system. If `$OPENCODE` is not `1` or `$AIDE_PLATFORM` is not `opencode`, abort immediately and inform the user that this skill is only supported on OpenCode. Do **not** attempt to query other databases (e.g. Claude Code's storage) — the schema is OpenCode-specific. If `$AIDE_SESSION_ID` is not set, abort with a message explaining that the session ID could not be determined. ## Workflow Run the following queries **sequentially** in a single Bash call (chain with `&&`). Present results to the user in a formatted summary after all queries complete. ### Step 1: Validate environment ```bash test "$OPENCODE" = "1" && echo "Platform: OpenCode" || echo "ERROR: Not running on OpenCode (OPENCODE=$OPENCODE)" test "$AIDE_PLATFORM" = "opencode" && echo "AIDE Platform: opencode" || echo "WARNING: AIDE_PLATFORM=$AIDE_PLATFORM" test -n "$AIDE_SESSION_ID" && e...
