investigation-report

investigation-report is a skill for Claude Code, Codex from aeonfun/aeon. It costs 52 tokens per session (8,027 once invoked), scanned A, original, MIT.

A one-command security investigation for a token on Base, an Ethereum-compatible blockchain network. It combines selected checks into one report and verdict.

In plain words
What is it for?
Use it to check for rug-pull risk, contract permissions and proxies, deployer history, concentrated ownership, honeypot trading restrictions, and locked liquidity.
Why use it?
It brings several common token risks into one investigation instead of requiring separate checks for the contract, deployer, holders, trading behaviour, and liquidity.

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

investigation-report scanned grade A with 2 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 21d 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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -m 10 -s -X POST "$RPC" -H "Content-Type: application/json" -d '{

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 405 lines — stays where its author put it; the contents beside it link to each section on GitHub.

${var} — Base subject to investigate, plus optional flags: <token-address> [--checks=rug,contract,deployer,holders,honeypot,lp] [--depth=quick|deep]. The first token is the subject contract address (0x…, required). --checks= is a comma-list selecting which analyzers to run (default = all six). --depth= is quick (the old rug-scan fast path — minimal reads) or deep (full standalone logic of each selected check; default). If the subject address is empty, log REPORT_NO_TARGET and exit cleanly (no notify).

Examples:

  • 0xToken → all six checks, deep report.
  • 0xToken --checks=honeypot → only the honeypot simulation (reproduces the standalone honeypot-check exactly, incl. its HONEYPOT_* end-states).
  • 0xToken --checks=rug,lp --depth=quick → rug verdict + LP-lock, fast path.
  • 0xToken --checks=contract,deployer,holders --depth=deep → structural audit + deployer entity intel + full concentration.

The "tell me everything about this token" skill. Instead of running six checks by hand, this composes them into one structured report behind a selector: rug risk, contract audit (verification / owner powers / proxy), deployer trace (who shipped it and their history), holder concentration (whale risk), honeypot (can you actually sell?), and LP lock (can the team pull liquidity?) — with a one-line summary on top.

Designed to degrade gracefully: each selected section runs independently, so a section that needs a key (or returns nothing) is marked unavailable without aborting the rest. Selecting a single check makes the composite behave as that one analyzer — same steps, same thresholds, same notify format, same status codes.

Config

  • Subject = the first token of ${var} (validate: 0x + 40 hex). Chain = Base (chainid=8453, explorer basescan.org).
  • Etherscan v2 unified API (https://api.etherscan.io/v2/api?chainid=8453&…) — used by the rug, contract, deployer, holders checks. Works keyless at a lower rate limit.
  • Base RPC (${BASE_RPC_URL:-https://mainnet.base.org}) — used by honeypot, lp, and the eth_call/eth_getLogs/eth_getStorageAt/eth_getCode reads inside the other checks. Keyless; any standard JSON-RPC endpoint works.
  • Secrets (all optional):
    • ETHERSCAN_API_KEY (a.k.a. BASESCAN_API_KEY — same Etherscan v2 key) — appended to the Etherscan URL as &apikey=… via ./secretcurl's {ETHERSCAN_API_KEY} placeholder (never a bare $SECRET on the line, never a header). Raises the rate limit and unlocks verified source, full deployer history, and the holder list. Used by rug, contract, deployer, holders.
    • BASE_RPC_URL — overrides the default public Base RPC. Used by every RPC read; primary for honeypot and lp.
  • Preamble (run once, before dispatch): read memory/MEMORY.md and the last ~2–3 days of memory/logs/ so a repeat investigation can note what changed since last time and avoid re-reporting the same signal. Parse ${var} → subject address, --checks (default all six), --depth (default deep).

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.

investigation-report is a skill published in the GitHub repository aeonfun/aeon (782 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 8,027 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
