recon-fingerprint-triage

recon-fingerprint-triage is a skill for Claude Code, Codex from blisspixel/recon. It costs 80 tokens per session (2,999 once invoked), scanned A, original, Apache-2.0.

A review tool for maintainers of a catalog that identifies technology providers from public DNS records. DNS is the system that connects domain names with internet services.

In plain words
What is it for?
Use it to review unmatched DNS records, assess proposed detection rules, strengthen existing entries with independent evidence, and prepare catalog updates.
Why use it?
It helps decide which observations represent reliable catalog entries instead of treating every new DNS name as a useful discovery.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

recon-fingerprint-triage 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 yesterday.

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 — 281 lines — stays where its author put it; the contents beside it link to each section on GitHub.

recon-fingerprint-triage

This skill reviews the bounded public DNS observations that recon already collects and helps maintainers improve the fingerprint catalog. It supports the multi-record v2.14 quality loop rather than treating catalog growth as a count of new CNAME suffixes.

This is the portable Agent Skills form used by the schema-pinned candidate. It omits client-only frontmatter and does not depend on experimental allowed-tools behavior. Package compatibility remains unclaimed until the frozen representative-client evaluation is complete.

When to use this

Use this skill when the user wants to:

  • review unmatched DNS observations by record type;
  • triage a private catalog baseline or recurrence queue;
  • assess a proposed fingerprint rule;
  • strengthen an existing slug with an independent evidence path;
  • prepare a catalog patch and its required fixtures.

For an ordinary domain lookup, use the base recon skill. This skill is for catalog maintenance, not general domain intelligence.

Environment and source checkout

An installed recon runtime or connected recon MCP server is enough to review user-supplied observations and inspect the current catalog. Use the tool names actually exposed by the client; no fixed MCP namespace or shell is required when those tools are already connected. For catalog absence, read the complete recon://fingerprints resource or page get_fingerprints(limit=20, offset=0) until a page contains fewer than 20 entries. These catalog reads are local.

Catalog patching, formatter changes, validation scripts, and repository tests require a separate recon source checkout selected by the user. Before using them, identify that checkout root and read its AGENTS.md and project guidance. Paths under docs/, src/, scripts/, validation/, and tests/ below refer to that checkout, not the installed skill directory or an arbitrary working directory. Documentation links may be read when browsing is available; they do not provide executable scripts or a writable checkout.

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.

recon-fingerprint-triage is a skill published in the GitHub repository blisspixel/recon (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 80 tokens to every session and 2,999 once invoked, about $0.0004 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.
