ironmesh-audit

ironmesh-audit is a skill for Claude Code from WizTheAgent/IronMesh. It costs 40 tokens per session (722 once invoked), scanned A, original, MIT.

A viewer for IronMesh's tamper-evident security audit log. The log records events such as authentication failures, peer removals, key changes, and detected attacks.

In plain words
What is it for?
Use it to review recent security events, filter for a particular event type, and investigate trust mismatches, blocked authentication, dropped peers, or possible attacks.
Why use it?
It helps investigate connection failures and security warnings while showing whether the audit history has been altered.

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

ironmesh-audit 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.

IronMesh audit log

Reads the last N entries from the HMAC-chained audit log. Used for security investigations — every entry is chained to the previous via HMAC-SHA256, so tampering breaks the chain and ironmesh audit verify will flag it.

When to use

  • User reports "can't connect to X" — look for TOFU_MISMATCH or AUTH_BLOCKED
  • Investigating a peer that went offline — look for PEER_DROPPED_LONG
  • Security review — look for any unexpected KEY_ROTATION, REPLAY_DETECTED, or DECRYPT_FAILURE

How to run

: "${IRONMESH_AUDIT_LOG:=$HOME/.ironmesh/audit.log}"

LIMIT="${1:-50}"
FILTER="${2:-}"   # optional: grep filter (e.g. TOFU_MISMATCH)

if [ ! -f "$IRONMESH_AUDIT_LOG" ]; then
    echo "No audit log at $IRONMESH_AUDIT_LOG"
    exit 1
fi

tail -n "$LIMIT" "$IRONMESH_AUDIT_LOG" \
  | ( [ -n "$FILTER" ] && grep -i "$FILTER" || cat ) \
  | python3 -c "
import json, sys, datetime
for line in sys.stdin:
    try:
        e = json.loads(line)
        ts = datetime.datetime.fromtimestamp(e['timestamp']).strftime('%Y-%m-%d %H:%M:%S')
        event = e.get('event', '?')
        data = e.get('data', {})
        print(f'{ts} {event:<22} {json.dumps(data)}')
    except Exception:

Known events

Event Meaning
STARTUP / SHUTDOWN Daemon lifecycle
PEER_CONNECT / PEER_DISCONNECT Normal peer state changes
PEER_DROPPED_LONG Peer offline past threshold (default 5 min) — investigate
TOFU_NEW_PEER First time we saw this peer identity — normal at init
TOFU_MISMATCH MITM candidate — peer presented a different key than pinned
AUTH_FAILURE Wrong passphrase or malformed challenge
AUTH_IP_BLOCKED 3 auth failures in 5 min → IP blocked for 5 min
DECRYPT_FAILURE / E2E_DECRYPT_FAILURE Ciphertext failed verification — protocol bug or attacker
SIGNATURE_FAILURE Ed25519 signature didn't verify
REPLAY_DETECTED Replayed sequence number or timestamp
KEY_ROTATION Session key rotated (expected periodically)
ROUTE_ANNOUNCED / ROUTE_LEARNED / ROUTE_EXPIRED Mesh routing table 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.
