indepth-recon-analysis

indepth-recon-analysis is a skill for Claude Code, Codex from Samurai-goose/SPECTER-The-Illusive-Security-Protocol. It costs 37 tokens per session (1,772 once invoked), scanned A, original, MIT.

A security-review skill that studies reconnaissance data—the information gathered about a system—to map its attack surface, meaning its exposed services, entry points, technologies, and possible weaknesses.

In plain words
What is it for?
Use it during an authorized security assessment to inventory domains, subdomains, IP addresses, ports, web applications, data flows, and potential attack paths.
Why use it?
It turns scattered scan results, web responses, API details, or source code into an organized view of where a system may be reachable or vulnerable.

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

indepth-recon-analysis 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 11d 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.

In-Depth Recon Analysis

Purpose

Systematically analyze reconnaissance data to map the full attack surface of a target. Identify exposed services, technology stacks, entry points, data flows, and potential weaknesses. Transform raw recon into actionable intelligence for downstream security skills.

Triggers

  • New target authorized for assessment
  • User provides recon data (subdomains, ports, endpoints, technology fingerprints)
  • User requests attack surface mapping
  • Pre-engagement scoping requires surface analysis
  • Source code available for analysis of exposed functionality

Required Inputs

Input Description Required
governance_context Active engagement governance record Yes
target Target application, domain, or repository Yes
recon_data Any combination of: subdomain lists, port scans, HTTP responses, technology fingerprints, directory listings, source code, API documentation At least one

Workflow

  1. Scope Verification — Confirm all recon targets are within authorized scope.

  2. Asset Inventory — Catalog all discovered assets:

    • Domains and subdomains
    • IP addresses and open ports
    • Web applications and endpoints
    • API endpoints (REST, GraphQL, WebSocket, gRPC)
    • Login/authentication pages
    • File upload/download endpoints
    • Admin/management interfaces
    • Third-party integrations
  3. Technology Fingerprinting — Identify:

    • Web servers (nginx, Apache, IIS, etc.)
    • Application frameworks (Express, Django, Rails, Spring, etc.)
    • Frontend frameworks (React, Angular, Vue, etc.)
    • CMS platforms (WordPress, Drupal, etc.)
    • Database technologies (inferred from errors, headers, behavior)
    • Cloud services (AWS, Azure, GCP indicators)
    • CDN/WAF presence (Cloudflare, Akamai, etc.)
    • Version numbers where observable
    • AI/LLM indicators:
      • AI chatbot or assistant interfaces (conversational UI patterns)
      • API endpoints calling AI providers (network requests to api.openai.com, api.anthropic.com, generativelanguage.googleapis.com, etc.)
      • Streaming response patterns (SSE with data: lines, chunked AI output)
      • RAG/knowledge base indicators (vector search endpoints, embedding APIs)
      • AI plugin or function-call patterns in API responses
      • Client-side AI SDK inclusion (OpenAI JS SDK, LangChain browser build)

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.

indepth-recon-analysis is a skill published in the GitHub repository Samurai-goose/SPECTER-The-Illusive-Security-Protocol (2 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 1,772 once invoked, about $0.0002 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.
