Secured Watch

Secured Watch is a skill for Claude Code, Codex from aaronjmars/aeon-agent. It costs 50 tokens per session (3,363 once invoked), scanned A, original, MIT.

A monitor for the public “Secured by Aeon” leaderboard, which lists open-source repositories that received security fixes or advisories. It compares the current list with the previous run and reports new or changed entries.

In plain words
What is it for?
Use it to track newly secured repositories and changes to a repository’s severity, star count, or fix link.
Why use it?
It removes the need to manually check the leaderboard and spot changes. It can stay quiet when nothing has changed.

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

Secured Watch scanned grade A with 1 finding 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

${var} — Optional flags:

  • empty (default) — diff against the last run; report only new + changed entries.
  • dry-run — render the report to stdout; write no state, send no notification.
  • full — report the entire current board (all secured repos), not just the diff. Still advances state.

Today is ${today}. This skill watches https://www.aeon.fun/security — the public "Secured by Aeon" leaderboard, the list of open-source repos the vuln-scanner pipeline has hardened (each row = a merged fix PR or a published advisory). It runs on a schedule (every ~2 days) and its whole job is to surface what's new since last time: repos that just joined the board, and existing entries whose fix link or severity changed (a follow-up PR, a re-disclosure, an escalation).

Silence on no change. A run where nothing was added and nothing changed sends no notification — it only advances state and logs. Do not send an empty report.

State

Snapshot of the last-seen board:

STATE = memory/state/secured-repos.json

Schema:

{
  "updated_at": "YYYY-MM-DD",
  "total_repos": 58,
  "total_stars": 1712345,
  "repos": {
    "owner/repo": { "severity": "HIGH", "stars": 257892,
                    "fix_url": "https://github.com/owner/repo/pull/123",
                    "note": "one-line fix description (fixed upstream Jun 17, 2026)" }
  }
}

owner/repo is the identity key. First run (no state file): this is the baseline — seed the snapshot from the current board and send one concise baseline line (Now tracking N secured repos …), then stop. New/changed entries are reported from the next run onward. Never emit a wall of 58 "new" repos on the first run.

Steps

  1. Fetch + parse + diff deterministically. The board is server-rendered HTML; each secured repo is an <a> whose aria-label reads owner/repo - <severity> severity, <N> stars (severity may be compound, e.g. HIGH+MEDIUM, HIGH×2), with the fix link in href and the fix description + date in title. The separator before the severity is a literal - (spaces required) — repo names contain hyphens, so a spaceless dash is not the separator. Run this to fetch, parse all rows, diff against state, write the new snapshot, and emit the report:

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.
