Last30days

last30days v3.0.0

Use last30days when the user wants recent, cross-source evidence from the last 30 days.

The runtime is a single v3 pipeline:

1. plan the query
2. retrieve per (subquery, source)
3. normalize and dedupe
4. extract best snippets
5. fuse with weighted RRF
6. rerank with one relevance score
7. cluster evidence
8. render ranked clusters

Setup: choose a Python 3.12+ runtime

Treat relative paths in this file as relative to this SKILL.md. The main runtime lives at ../../scripts/last30days.py.

for py in python3.14 python3.13 python3.12 python3; do
  command -v "$py" >/dev/null 2>&1 || continue
  "$py" -c 'import sys; raise SystemExit(0 if sys.version_info >= (3, 12) else 1)' || continue
  LAST30DAYS_PYTHON="$py"
  break
done

if [ -z "${LAST30DAYS_PYTHON:-}" ]; then
  echo "ERROR: last30days v3 requires Python 3.12+. Install python3.12 or python3.13 and rerun." >&2
  exit 1
fi

Runtime expectations

• One reasoning provider is required: GOOGLE_API_KEY for Gemini, OPENAI_API_KEY for OpenAI, or XAI_API_KEY for xAI.
• BRAVE_API_KEY enables Brave web search (recommended). SERPER_API_KEY is the web fallback.
• SCRAPECREATORS_API_KEY enables Reddit, TikTok, and Instagram.
• XAI_API_KEY enables xAI reasoning and X search.
• AUTH_TOKEN plus CT0 enables Bird-backed X search.
• yt-dlp enables YouTube.
• Planning and reranking fall back gracefully: Gemini -> OpenAI -> xAI -> deterministic/local.
• Web retrieval stays within Brave/Serper dated results. Undated web hits are dropped.

Output model

• compact and md: cluster-first markdown
• json: full v3 report
• context: short synthesis-oriented context

Important report fields:

• provider_runtime
• query_plan
• ranked_candidates
• clusters
• items_by_source
• errors_by_source

Usage guidance for agents

• Prefer --quick for fast iteration.
• Prefer default mode when the user wants a balanced answer.
• Prefer --deep only when the user explicitly wants maximum recall or the topic is complex enough to justify extra latency.
• Prefer --emit=json when downstream code or evaluation will consume the result.
• Use --search= only when the user explicitly wants source restrictions.

X handle resolution

If the topic could have its own X/Twitter account (people, brands, products, companies), use the available web search tool to look for their handle with a query like:

{TOPIC} X twitter handle site:x.com

If you find a verified handle, pass --x-handle={handle} (without @). This searches their posts directly, finding content they posted that doesn't mention their own name. Skip this for generic concepts ("best headphones 2026", "how to use Docker").

Synthesis guidance

First: synthesize, don't summarize

Extract key facts from the output first, then synthesize across sources. Lead with patterns that appear across multiple clusters. Present a unified narrative, not a source-by-source summary.

Ground in actual research, not pre-existing knowledge

Use exact product/tool names, specific quotes, and what sources actually say. If research mentions "ClawdBot" and "@clawdbot", that is a different product than "Claude Code" -- read what the research actually says.

Anti-pattern to avoid:

• BAD: User asks "best Claude Code skills" and you respond with generic advice: "Skills are powerful. Keep them under 500 lines."
• GOOD: You respond with specifics from the research: "Most mentioned: /commit (5 mentions), remotion skill (4x), git-worktree (3x). The Remotion announcement got 16K likes on X per @thedorbrothers."

Source weighting (highest to lowest signal)

1. Cross-cluster corroboration -- same evidence across multiple sources is the strongest signal. Lead with it.
2. Reddit top comments -- often the wittiest, most insightful take. Quote directly when upvotes are high.
3. YouTube transcript highlights -- pre-extracted key moments. Quote and attribute to channel name.
4. X/Twitter @handles -- real-time community signal. Quote with engagement context.
5. Polymarket odds -- real money on outcomes cuts through opinion. Include specific odds AND movement.
6. TikTok/Instagram -- viral/creator signal. Cite @creators with views/likes.
7. Hacker News -- technical community perspective. Cite as "per HN."
8. Web (Brave/Serper) -- cite only when social sources don't cover a fact.

Polymarket interpretation

When Polymarket returns relevant markets:

1. Prefer structural/long-term markets over near-term deadlines (championship odds > regular season, IPO > incremental update)
2. Call out the specific outcome's odds and movement, not just that a market exists
3. Weave odds into the narrative as supporting evidence, don't isolate them
4. When multiple relevant markets exist, highlight 3-5 ordered by importance

Domain importance ranking:

• Sports: Championship/tournament > conference title > regular season > weekly matchup
• Geopolitics: Regime change/structural > near-term strike deadlines > sanctions
• Tech/Business: IPO, major product launch > incremental updates
• Elections: Presidency > primary > individual state

Citation rules

Cite the single strongest source per point in short format: "per @handle" or "per r/subreddit". Save engagement metrics for the stats section. Use the priority order from source weighting above. The tool's value is surfacing what PEOPLE are saying, not what journalists wrote.

Comparison queries

For "X vs Y" queries, structure output as:

## Quick Verdict
[1-2 sentences: which one the community prefers and why, with source counts]

## [Entity A]
**Community Sentiment:** [Positive/Mixed/Negative] (N mentions across sources)
**Strengths:** [with source attribution]
**Weaknesses:** [with source attribution]

## [Entity B]
[Same structure]

## Head-to-Head
| Dimension | Entity A | Entity B |
|-----------|----------|----------|
| [Key dim] | [position] | [position] |

## Bottom Line
Choose A if... Choose B if... (based on community data)

Recommendation queries

When users ask "best X" or "top X", extract SPECIFIC NAMES:

Most mentioned:
[Name] -- Nx mentions
  Sources: @handle1, r/subreddit, [YouTube channel]

[Name] -- Nx mentions
  Sources: @handle2, r/subreddit2

Notable mentions: [others with 1-2 mentions]

Edge cases

• Empty results from a source: State what is missing. ("No Reddit discussion found for this topic.") Do not fill the gap with training data.
• Sources contradict each other: Present both sides with attribution. ("Reddit r/fitness is bullish on X, while @DrExpert on X warns about Y.")
• All results are low-engagement or off-topic: Acknowledge uncertainty. ("Limited recent discussion found -- these findings should be treated as preliminary.")

Follow-up conversations

After research completes, treat yourself as an expert on this topic. Answer follow-ups from the research findings. Cite the specific threads, posts, and channels you found. Only run new research if the user asks about a DIFFERENT topic.

Security and permissions

What this skill does:

• Sends search queries to ScrapeCreators API for Reddit, TikTok, Instagram search
• Sends search queries via xAI API or Bird client for X search
• Sends search queries to Algolia HN Search API (free, no auth)
• Sends search queries to Polymarket Gamma API (free, no auth)
• Runs yt-dlp locally for YouTube search and transcript extraction (no API key)
• Sends search queries to Brave Search API or Serper for web search (optional)
• Uses Gemini, OpenAI, or xAI for LLM planning and reranking
• Stores findings in local SQLite database (--store mode only)

What this skill does NOT do:

• Does not post, like, or modify content on any platform
• Does not access your personal accounts on any platform
• Does not share API keys between providers
• Does not log or cache API keys in output files
