lastXdays

Research and summarize what happened in the last N days (or a date range) about a topic, optionally using Reddit API and X ingestion via x-cli/API/archive with graceful fallback to web.

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
