feat: add --no-native-web flag to skip Parallel AI in Claude Code

When running in Claude Code, the assistant has a built-in WebSearch tool
that's free and higher quality than Parallel AI/Brave/OpenRouter. Adding
--no-native-web to the SKILL.md invocation defers web search to the
assistant, saving API credits. OpenClaw invocations don't pass this flag,
so they continue using native web backends.

+# feat: Skip native web search when running in Claude Code
+
+**Type:** enhancement
+**Date:** 2026-03-03
+**Detail level:** MINIMAL
+
+## Problem
+
+When `/last30days` runs in Claude Code, web search happens twice:
+1. The Python script uses Parallel AI / Brave / OpenRouter (costs API credits)
+2. SKILL.md tells Claude to run its built-in WebSearch tool (free, better quality)
+
+This is redundant. Claude's WebSearch is better and free. In OpenClaw, there's no WebSearch tool, so native backends are essential there.
+
+## Solution
+
+Add a `--no-native-web` CLI flag to `last30days.py`. When set, the script skips native web search backends even if API keys are configured, and emits the `### WEBSEARCH REQUIRED ###` signal so the assistant handles it.
+
+Update SKILL.md invocation to include the flag.
+
+## Changes
+
+### 1. `scripts/last30days.py`
+- [ ] Add `--no-native-web` argument to argparse (store_true, default False)
+- [ ] When `args.no_native_web` is True, force `web_backend = None` regardless of API keys
+- [ ] This naturally triggers `web_needed = True` → emits `### WEBSEARCH REQUIRED ###` signal
+- [ ] Update diagnostic banner to show "Web: deferred to assistant" when flag is active
+
+### 2. `SKILL.md`
+- [ ] Add `--no-native-web` to the invocation command on line 168:
+  ```
+  python3 "${SKILL_ROOT}/scripts/last30days.py" "$ARGUMENTS" --emit=compact --no-native-web
+  ```
+
+### 3. OpenClaw / `--agent` mode
+- [ ] No changes needed — OpenClaw invocations don't read SKILL.md, they call the script directly without `--no-native-web`, so Parallel AI/Brave/OpenRouter still work
+
+## Acceptance Criteria
+
+- [ ] Claude Code sessions: script skips Parallel AI, Claude uses WebSearch (no API credits spent)
+- [ ] OpenClaw sessions: script still uses Parallel AI / Brave / OpenRouter as before
+- [ ] `--no-native-web` flag can be combined with `--include-web` (flag wins, web deferred)
+- [ ] Diagnostic output clearly shows web is deferred to assistant
