Summary

Updates docs/smith.md to match the current Smith implementation, tool inventory, three approval modes, context management, and provider configuration.

• Tool inventory: Replaces obsolete file read/write/list/find tool descriptions with the current Codex-style minimal local coding tools (shell, write_stdin, edit_file supporting multi-hunk / multi-file batch edits and file creation), Chrome DevTools browser tools (browser_open, browser_inspect, browser_screenshot, browser_eval), and daemon/fleet control tools including recurring loops (agentd_loop_*), playbook operations (agentd_playbook_get, agentd_playbook_edit), and Smith-owned subagents (agentd_subagent_*).
• Three approval modes & transitions: Replaces obsolete boolean automode with the three explicit approval modes (manual, auto_review, always-approve / unsafe_auto on the wire). Details Safe vs Risky classifications, dynamic Safe downgrades (shell with read_only: true, edit_file within auto-approved paths), inline approval prompt keys (y/n/a/f), mode cycling (C-x A / A / modeline badge click), and initial override via CONSTRUCT_SMITH_AUTOMODE=1.
• Context management & compaction: Documents tool output truncation (8 KiB budget), automatic context compaction before pruning (AUTO_COMPACT_RATIO = 0.65, [Compacted earlier context], DEFAULT_KEEP_PAIRS = 4), manual /compact [N], and rolling prune at 70% utilization.
• Provider & config drift: Adds OpenRouter (openrouter:, OPENROUTER_API_KEY, profile support, and fallback ladder position); documents CODEX_HOME and CONSTRUCT_CLAUDE_OAUTH_CREDENTIALS; clarifies that CONSTRUCT_CLAUDE_BIN / CONSTRUCT_CLAUDE_CMD configure the standalone claude CLI adapter harness rather than Smith's claude-oauth:; and documents CONSTRUCT_SMITH_FLEET_TOOLS=off and CONSTRUCT_SMITH_AUTO_COMPACT=off.
