lastXdays Skill

Summarize what happened in the last N days (or a specific YYYY-MM-DD → YYYY-MM-DD range) about a user-provided topic.

Default behavior is web-first (web_search + selective web_fetch). If optional credentials/data are available, you may ingest Reddit via API and X via x-cli (preferred), API, or local archive, falling back to web search if unavailable.

Trigger Patterns

Activate when the user message contains any of: - lastXdays / lastxdays - last x days - A question like: "what happened in the last N days" (optionally followed by a topic)

Default Model

Default to sonnet (anthropic/claude-sonnet-4-6) when spawning as a subagent.

Use flash (openrouter/google/gemini-2.0-flash-001) only for simple single-source lookups (one topic, one platform, straightforward synthesis with no file reading required). Flash is unreliable for multi-step agentic work requiring tool chaining (search → fetch → read files → synthesize → report). When in doubt, use sonnet.

Input Parsing

Parse from the user message:

1) Date range (preferred if explicit)

If the user supplies a range like: - from 2026-01-10 to 2026-02-08 - 2026-01-10 → 2026-02-08

Then: - start = YYYY-MM-DD - end = YYYY-MM-DD - Ignore N if both are present.

2) Days (N)

Otherwise, infer N: - Look for an integer N associated with the request, e.g.: - lastxdays 7 <topic> - 7 lastxdays <topic> - what happened in the last 14 days (about|re:) <topic> - Default: N = 30 - Clamp: N = min(max(N, 1), 365)

3) Sources (optional)

Supported: web|reddit|x|all.

Accept any of: - for web / sources web - for reddit / sources reddit - for x / sources x - for all / sources all

If unspecified: sources = all.

4) Topic

• The remaining text (after removing trigger words, N/range, and source phrases) is the topic.
• If topic is empty/unclear, ask exactly one clarifying question and stop.

Date Range (freshness)

Use an inclusive range in local time: - freshness = start + "to" + end (e.g., 2026-01-10to2026-02-08)

Helper for “last N days”: - node scripts/lastxdays_range.js <N>

Optional non-web ingestion (Reddit/X)

Use this helper to ingest Reddit/X when possible: - node scripts/lastxdays_ingest.js --source=reddit|x --topic "..." --start YYYY-MM-DD --end YYYY-MM-DD --limit 40

The script attempts: - Reddit: official API via OAuth (if credentials exist), else returns fallback:true - X: x-cli search first (if installed/configured), then Twitter API v2 recent search (if bearer token + range <= ~7 days), then local archive at ~/clawd/data/x-archive/, else returns fallback:true

Required environment variables (if you want API mode):

• Reddit:
• REDDIT_CLIENT_ID
• REDDIT_CLIENT_SECRET
• either REDDIT_REFRESH_TOKEN (recommended) or REDDIT_USERNAME + REDDIT_PASSWORD

• optional: REDDIT_USER_AGENT

• X API (optional; only works for recent ranges on most tiers):

• X_BEARER_TOKEN (also accepts TWITTER_BEARER_TOKEN)

• x-cli (optional, preferred for agent use):

• Install: uv tool install x-cli (or from source)
• Configure credentials in ~/.config/x-cli/.env (supports shared setup with x-mcp)
• If present, lastxdays_ingest.js uses it before raw API/archive for X search

Credentials loader: - Reads ~/.config/last30days/.env if present (does not hard-fail if missing) - Environment variables override .env values (file only fills blanks)

Research Procedure

1) Compute start/end/freshness.

2) For each requested source:

Web

• Query: <topic>
• Run web_search with freshness (count 5–8)
• Optionally web_fetch 2–6 best links

Reddit

Preferred: - Run node scripts/lastxdays_ingest.js --source=reddit ... - If it returns fallback:false, treat returned items[] as “Notable links” (each has a Reddit permalink URL). - If items[] is empty / too small to be useful (e.g., <3), you may also run the web fallback to broaden coverage.

Fallback (if fallback:true): - Run web_search with query site:reddit.com/r <topic> and the same freshness

X

Preferred: - Run node scripts/lastxdays_ingest.js --source=x ... - If mode=x-cli, mode=api, or mode=archive, treat returned items[] as “Notable links” (each has a URL) - If mode=x-cli, note that X results came from local x-cli execution - If mode=archive, note that links come from the local X archive - If items[] is empty / too small to be useful (e.g., <3), you may also run the web fallback to broaden coverage.

Fallback (if fallback:true): - Run web_search with query site:x.com <topic> and the same freshness - Expect web_fetch to fail often on x.com; rely on snippets when needed

3) Select and deduplicate links/items: - Prefer authoritative sources for Web - Prefer high-engagement or highly-informative posts for Reddit/X - Keep total links/items shown to ~10–20 max

Output Format (Markdown)

Title: - ## lastXdays — <N> days — <topic> - If an explicit range was used, you may replace <N> days with YYYY-MM-DD → YYYY-MM-DD.

Then include sections in this order:

1) Date range used - YYYY-MM-DD → YYYY-MM-DD (and optionally the freshness string)

2) Top themes - 3–7 bullets summarizing the dominant storylines/trends

3) Notable links Group by platform in this order, including only platforms actually searched: - Web - Reddit - X

For each link/item: - Markdown link - One line: why it matters - If snippet-only (fetch failed/unavailable), say so

4) What to follow up on - 3 copy/pasteable next searches

Smoke tests (local)

Date range helper: - node scripts/lastxdays_range.js 7

Reddit ingest (requires creds or it will return fallback=true): - node scripts/lastxdays_ingest.js --source=reddit --topic "OpenClaw security vulnerability CVE" --start 2026-02-07 --end 2026-02-08 --limit 20 --pretty

X ingest (x-cli if installed; else API if bearer token + <=7 days; else local archive; else fallback=true): - node scripts/lastxdays_ingest.js --source=x --topic "OpenClaw" --start 2026-02-07 --end 2026-02-08 --limit 20 --pretty

Optional x-cli direct smoke test: - x-cli -v -j tweet search "OpenClaw since:2026-02-07 until:2026-02-09" --max 20
