Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.01235 |
| Opus 5.5 | $0.00033 | $0.00494 |
| Sonnet 5.5 | $0.00016 | $0.00247 |
| Haiku 4.5 | $0.00008 | $0.00123 |
Grade A, and why
network-path-diagnose 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 1mo 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.

Diagnose network path quality from this host to a target using ping/mtr/curl. How it starts
The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Network path diagnosis
Measure reachability and path quality (packet loss, latency, jitter) from this host to a user-specified target.
Out of scope: cloud VPC/security-group debugging, whole-host lag checks (diagnose_system_lag), DNS-only failures (dns-diagnose), changing routes or firewall rules.
Rules
- Need a target first: ask for IP/host/URL if missing; do not invent defaults.
- Read-only probes: ping/mtr/curl/ss are fine; do not change NICs, routes, or firewall.
- Stop when enough: stop once the symptom is explained; do not add unrelated probes.
- Missing tools: if
mtris absent, fall back toping+traceroute/tracepathand note that in Evidence. - Uncontrollable peers: for public DNS and similar hosts you cannot log into, run forward tests only and state that reverse MTR is impossible.
Workflow
Confirm target & symptom → quick reachability → path quality (mtr) → TCP/port follow-up if needed → answer
1. Confirm inputs
| Input | Notes |
|---|---|
| Target | IP, hostname, host:port, or URL |
| Symptom | unreachable / slow / intermittent loss / bad at certain times |
| Port/protocol | record TCP port if the app uses one (e.g. 443/22) |
2. Quick reachability
getent ahosts <host> | head -5
ping -c 5 -W 2 <host>
curl -sS -o /dev/null -w '%{http_code} time=%{time_total}\n' --connect-timeout 5 <URL>
# or
nc -zv -w 3 <host> <port> 2>&1
- Resolve fails → use or hand off to
dns-diagnose; continue only with a user-provided IP. - ICMP all lost but TCP port works → ICMP likely filtered; switch to TCP path tests; do not call the path “dead”.
3. Path quality (prefer mtr)
command -v mtr
mtr -rwzc 50 <host>
# without mtr:
traceroute -n <host> 2>/dev/null || tracepath -n <host>
ping -c 20 -W 2 <host>
How to read results
| Pattern | Likely meaning |
|---|---|
| High loss on middle hops, last hop and destination OK | Middle boxes may rate-limit ICMP; trust the last hop more |
| Sustained loss or high latency on the last hop | Path or peer/egress problem |
| Latency jumps after a hop | Bottleneck often after that hop |
| Occasional jitter, no sustained loss | Congestion or local Wi-Fi/interference; retest later |
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.

network-path-diagnose is a skill published in the GitHub repository AI-Shell-Team/aish (568 stars, last pushed 2d ago), licensed Apache-2.0. It adds 82 tokens to every session and 1,235 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
