url-insight

url-insight is a skill for Claude Code from MikkoParkkola/nab. It costs 127 tokens per session (12,971 once invoked), scanned A, original, MIT.

A URL-analysis workflow that sorts links such as papers, products, repositories, blogs, documentation, and benchmarks into useful portfolio insights.

In plain words
What is it for?
Use it to assess whether an idea is worth adopting, map research or competitor signals to repositories, rank potential actions, and file prioritised Linear issues after critical review.
Why use it?
It reduces noise in batches of links and checks whether a URL has already been reviewed before spending time fetching and analysing it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

url-insight scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (dedup_precheck.py, refresh_portfolio.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 874 lines — stays where its author put it; the contents beside it link to each section on GitHub.

url-insight — URL batches → portfolio insights → DoR issues

Fires on: multi-URL paste · "analyze these urls" · "should we adopt X" · "competitive signal" · "worth a spike" · arxiv/HN/ProductHunt/GitHub URLs in bulk. Purpose: compress a firehose of URLs into ranked, evidence-backed actions against the 21-active-repo portfolio. Noise → IGNORE. Signal → specialist agent panel → Linear ticket with devil + steelman reckoning.

Design: Fukasawa (paste URL → pipeline fires) · Rams #10 (8 labels, not 30) · Honest (IGNORE is first-class) · Calibrated (devil + steelman together).


0 · MANDATORY protocol (non-negotiable, like hebb/linear)

  1. Before fetching any URL: run the dedup pre-check in §0.1. If hebb or Linear finds a prior verdict, skip fetch, skip nab, and report Already triaged: <MIK-id>, verdict=<ADOPT|IGNORE|INSPIRE|SUPERCHARGE|HUMAN-REVIEW>, ROI=<n>x with the issue link.
  2. After each URL is classified + scored: write the hebb dedup pin in §0.1 with project="url-insight" and key schema url-<sha256-of-canonical-url>-<iso-date>.
  3. Before filing any issue: run devil's advocate (§6) AND steelman (§6.5). Quote both verbatim in issue body.
  4. For SUPERCHARGE: dispatch innovator agent FIRST (serial gate). If kill → drop signal. If proceed → parallel fan-out: moonshot-architect + business-panel + research patent-prior-art.
  5. For FAIL-FAST SPIKE: surface user prompt "file issue / also spawn <1h spike agent?" (unless --auto-spike flag).
  6. Emit innovation-tracker queue entry per actionable insight (§10).
  7. Wayback evidence capture (BLOCKING for non-IGNORE): after a successful fetch, call fulcrum:wayback_save with if_not_archived_within="7d" and capture_screenshot="1"; persist wayback_url or wayback_save_failed=true in the run JSON (§1.1). Capture failure is evidence debt, not a triage blocker.
  8. Dual output: JSON artifact ~/.claude/data/url-insight/run-TIMESTAMP.json + markdown report.
  9. Living-document update (BLOCKING for non-IGNORE): append delta line(s) with [^N] citation(s) to ~/.claude/data/portfolio/market-positioning-living.md per §0.8. No skipping. No "I'll do it later". The doc rots without per-URL writes.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
