dossier

dossier is a skill for Claude Code, Codex from Crawlio-app/crawlio-browser. It costs 19 tokens per session (868 once invoked), scanned A, original, Apache-2.0.

A competitive intelligence skill for comparing one website with two to four competitor websites. It examines areas such as technology, speed, accessibility, and search visibility, then groups the findings.

In plain words
What is it for?
Use it to create competitor analyses, compare website quality, and produce organized strengths, weaknesses, and opportunities.
Why use it?
It replaces scattered website checks with a structured comparison that shows where a site leads, lags, or could improve.

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

dossier 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 5d ago.

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.

Dossier — Competitive Intelligence

Compare a target site against 2-4 competitors across all 11 comparison dimensions. Aggregate strengths, weaknesses, and opportunities as structured findings.

When to Use

  • Building a competitive analysis across multiple sites
  • Comparing tech stacks, performance, accessibility, SEO head-to-head
  • Identifying where a target leads or lags vs competitors
  • Producing a structured strengths/weaknesses/opportunities report

Protocol

  1. search for comparison commands: search("compare pages") or search("extract page")
  2. connect_tab to the target URL with { background: true }
  3. execute Code Mode to run smart.comparePages() for each target-vs-competitor pair
  4. Emit one smart.finding() per dimension per pair
  5. After all pairs, return smart.findings() grouped by dimension

Code Example

const target = "https://target.com";
const competitors = ["https://comp-a.com", "https://comp-b.com"];

// Compare target vs each competitor
for (const comp of competitors) {
  const comparison = await smart.comparePages(target, comp);

  for (const dim of comparison.scaffold.dimensions) {
    if (!dim.comparable) continue;
    smart.finding({
      claim: `${dim.name}: ${target} vs ${comp}`,
      evidence: [
        `target (${dim.siteA.type}): ${JSON.stringify(dim.siteA.value)}`,
        `competitor (${dim.siteB.type}): ${JSON.stringify(dim.siteB.value)}`
      ],
      sourceUrl: target,
      confidence: "high",
      method: "comparePages",
      dimension: dim.name
    });
  }

  // comparePages returns PageEvidence, not technographic results. Detect each stack explicitly.
  const compTech = (await smart.detectTechnologies()).technologies.map(t => t.name);
  await smart.navigate(target);
  const targetTech = (await smart.detectTechnologies()).technologies.map(t => t.name);
  if (targetTech.length || compTech.length) {
    smart.finding({
      claim: `Tech stacks differ: target [${targetTech.join(", ")}] vs ${comp} [${compTech.join(", ")}]`,
      evidence: [`target: ${targetTech.join(", ")}`, `competitor: ${compTech.join(", ")}`],
      sourceUrl: target,
      confidence: "high",
      method: "detectTechnologies",
      dimension: "framework"
    });
  }
}

// Visual reference of target
await smart.scrollCapture();

return { findings: smart.findings(), totalComparisons: competitors.length };

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.

dossier is a skill published in the GitHub repository Crawlio-app/crawlio-browser (6 stars, last pushed 26d ago), licensed Apache-2.0. It adds 19 tokens to every session and 868 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
