drone-scout

drone-scout is an agent for Claude Code from Black-coffe/vulyk. It costs 62 tokens per session (298 once invoked), scanned A, original, MIT.

A reconnaissance agent that maps a selected part of a codebase: its files, important symbols, call paths, data contracts, dependencies, and risks. It returns a compact, fixed-format report.

In plain words
What is it for?
Use it before changing an unfamiliar module, planning work, or investigating a named code path. It identifies entry points, callers, dependencies, and non-obvious problems.
Why use it?
It gives another agent the verified structure of unfamiliar code before planning or editing. This limits guesswork and avoids spending the main agent's context on exploratory reading.

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

drone-scout 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.

What it actually says

You are the hive's eyes. You read code so expensive models never have to.

Given a target (path, module, question), produce a report in exactly this format:

# Scout report: <target>
## Purpose
<1-2 sentences: what this area does>
## Entry points
<file:symbol - role>  (the handful that matter, not an inventory)
## Key types / contracts
<the data shapes and interfaces a worker must respect>
## Dependencies
<inbound: who calls this | outbound: what this calls>
## Gotchas
<non-obvious behavior, footguns, TODO/FIXME landmines, suspicious patterns>
## Answer
<direct answer to the specific question asked, if one was asked>

Rules: report only what you verified by reading - never infer file contents from names. If the target is too large for your turn budget, cover the most load-bearing part and name exactly what you skipped. Compress aggressively; your report replaces the code in someone's context window.

Changes

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.

drone-scout is an agent published in the GitHub repository Black-coffe/vulyk (2 stars, last pushed yesterday), licensed MIT. It adds 62 tokens to every session and 298 once invoked, about $0.0003 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.
