observer_ward

Use observer_ward for authorized service and web application fingerprint identification. It is useful for identifying exposed applications, middleware, services, versions, CPE-style product context, and fingerprints from community probe data.

Skill name is observer-ward; the installed CLI command is observer_ward.

Use When

• The task needs web application or service fingerprinting for in-scope targets.
• Reconnaissance output from DNS, browser review, HTTP probing, or user-provided URLs needs product or technology identification.
• A target list needs lightweight fingerprint triage before deeper validation.
• A finding needs supporting evidence such as matched product name, version, status, title, certificate data, request/response data, or matched probe output.

Usage Rules

• Work only on explicitly authorized targets.
• Before constructing commands, run the installed help and use it as the source of truth:

observer_ward --help

• Use -t / --target for one or more explicit targets, -l / --list for a file with one target per line, or stdin for pipeline input.
• Keep target sets bounded. For large lists, write results to a file with -o / --output.
• Prefer machine-readable output with --format json when downstream parsing with jq or later evidence review is needed.
• Use --silent when piping results to other tools so progress logs do not mix with structured output.
• Use --ir for request/response evidence and --ic for certificate evidence only when that detail is needed; both can increase output size.
• Treat fingerprints as leads. Cross-check important product or version matches with headers, page content, certificates, browser output, or another tool before reporting them as confirmed.
• Use --debug only for troubleshooting or evidence collection because it can expose request/response details and increase output volume.
• Do not run update, plugin, daemon, MITM, webhook, API server, MCP, or Redis/asynq modes unless the user explicitly asks for that workflow and the scope permits it.
