observe

Query Crawlio's observation log — the append-only timeline of everything Crawlio observed during a crawl session.

When to Use

Use this skill when the user wants to:

See what happened during a crawl
Review extension captures (framework detection, network requests, console logs)
Reconstruct a timeline of events
Find specific observations by host, source, or time range

Quick Reference

Get Recent Observations

get_observations({ limit: 20 })

Filter by Host

get_observations({ host: "example.com", limit: 50 })

Filter by Source

Source	What It Captures
`extension`	Chrome extension enrichment (framework, network, console, DOM)
`engine`	Crawl lifecycle events (crawl_start, crawl_done)
`webkit`	WebKit runtime capture
`agent`	AI-created findings

get_observations({ source: "extension", limit: 30 })

Filter by Operation

Op	Meaning
`observe`	Raw data capture
`finding`	Agent-created insight
`crawl_start`	Crawl began
`crawl_done`	Crawl completed
`page`	Single page observation

get_observations({ op: "crawl_done" })

Time-Based Query

Use Unix timestamps to query a time range:

get_observations({ since: 1708444200, limit: 100 })

Combine Filters

get_observations({
  host: "example.com",
  source: "extension",
  op: "observe",
  limit: 50
})

Single Observation Lookup

Look up a specific observation or finding by ID:

get_observation({ id: "obs_a1b2c3d4" })

Use this to verify evidence referenced by findings, or to inspect the full payload of an evidenceId returned by analyze_page. Works with both obs_xxx (observation) and fnd_xxx (finding) IDs.

Reading Observations

Each observation entry contains:

id — unique identifier (obs_ prefix for observations, fnd_ for findings)
op — what type of event this is
ts — ISO 8601 timestamp
url — the URL this relates to
source — what produced this entry
data — composite payload (framework detection, network requests, console logs, progress, etc.)

Common Patterns

Timeline Reconstruction

Query by host with no limit to see the full story of a crawl:

get_observations({ host: "example.com" })

Crawl Summary

Get start and end events to see crawl performance:

get_observations({ op: "crawl_start" })
get_observations({ op: "crawl_done" })

The crawl_done entry includes progress data (totalDiscovered, downloaded, failed).

Extension Audit

See everything the Chrome extension captured:

get_observations({ source: "extension", limit: 200 })

Evidence Chain Verification

Verify evidence referenced by a finding:

get_observation({ id: "obs_a1b2c3d4" })

This returns the full observation entry. Use it to confirm that evidence IDs in findings actually support the claimed insight.

After Observation — Create Findings

Once you've identified patterns in observations, use the finding skill to record insights with evidence chains.
