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 | $0.00062 | $0.01179 |
| Opus 5 | $0.00031 | $0.00589 |
| Sonnet 5 | $0.00012 | $0.00236 |
| Haiku 4.5 | $0.00006 | $0.00118 |
Grade A, and why
nsm-session-pivot 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NSM Session Pivot (read-only)
MCP Server
- Server:
nsm-mcp(NetClaw-authored, spec 091) - Tools:
nsm_status,nsm_analyze,nsm_sessions,nsm_protocol_log - Engine: Zeek 8.2.1, pinned by image digest
- Input: a
.pcap/.pcapngfile already on disk. Nothing sniffs an interface.
The rule that matters most here
A missing protocol log does not mean there was no such traffic.
Zeek discards packets with invalid TCP checksums by default. Measured on a reference
capture: with validation on, Zeek produced no http.log at all — the HTTP request was
invisible — and a conn.log that was also wrong, 3 rows instead of the correct 2, because
discarded packets fragment the flow. The only signal is a warning on stderr.
Captures from a NIC with checksum offloading routinely have invalid checksums, including
the ones NetClaw's own cml-packet-capture and gns3-packet-capture skills produce.
So nsm-mcp defaults ignore_checksums=true, the opposite of Zeek's own default, and
attaches zeek_posture to every response:
state |
What it means |
|---|---|
IGNORING_CHECKSUMS |
all packets analysed — the correct setting for offloaded captures |
PACKETS_DISCARDED |
packets were dropped; protocol logs may be missing and conn.log may be wrong |
VALIDATING |
validation on, nothing flagged |
If you see PACKETS_DISCARDED, re-run with ignore_checksums=true before drawing any
conclusion. Reporting "no HTTP in this capture" from a discarded run is a wrong answer that
looks like a finding.
Workflow: reconstruct what happened
nsm_analyze— which Zeek logs did this capture produce, and how many connections?nsm_sessions— the connection table. Noteservice,conn_state, byte counts- Pick the connection of interest and record its
uid nsm_protocol_logwithlog="dns"/"http"/"ssl"and thatuid— every Zeek log sharesuidwithconn.log, which is what makes the pivot exact rather than heuristicnsm_protocol_logwithlog="weird"— protocol anomalies Zeek could not classify- Report the session narrative, stating the checksum posture you worked under
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.

nsm-session-pivot is a skill published in the GitHub repository automateyournetwork/netclaw (652 stars, last pushed 3d ago), licensed Apache-2.0. It adds 62 tokens to every session and 1,179 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 2026-09-03.
