Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 563 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 | $0.00081 | $0.05702 |
| Opus 5.5 | $0.00032 | $0.02281 |
| Sonnet 5.5 | $0.00016 | $0.01140 |
| Haiku 4.5 | $0.00008 | $0.00570 |
Grade A, and why
selfhost-emem-guard 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Check: `curl -s localhost:8080/health | grep verifies_citations` says `true`. How it starts
The opening of the file, as written. The whole thing — 597 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Self-host emem-guard
You are the operator. This procedure is written to be run by an agent with a shell, unattended, in one session. Every step is a command you can execute and a check you can evaluate. If a step cannot be run verbatim, that is a defect in this file: report it rather than improvising around it.
What you are building
Four diagrams, if the shape helps before the commands do: nine doors, one decision, one verdict, in order, the chassis your DLP runs on, three deployments.
A server that answers one question: should this prompt proceed, given the claims it makes about the physical world. It returns allow or deny, signs the verdict, and appends it to a log before answering, so the decision can be verified later by someone who does not trust you.
It is not a DLP scanner. It does not classify content. It checks whether the
emem: citations in a transcript still verify, and optionally whether
measurable claims about places carry a citation at all.
Before you start
You need:
- Rust 1.91 or newer (
rustc --version). - Nothing else to run it locally.
For the Anthropic Enterprise checkpoint specifically you also need a publicly reachable HTTPS URL on port 443 with a certificate that validates against the public CA trust store, because that platform refuses private, loopback and carrier-grade NAT ranges at connect time and does not follow redirects. The open routes have no such requirement: localhost is fine.
You do NOT need an emem account, an API key, or network access to emem.dev.
Step 1: build
git clone https://github.com/Vortx-AI/emem
cd emem
cargo build --release -p emem-guard
Check: the build exits 0. If it fails on ort-sys or a GPU crate, you have
built the wrong package; -p emem-guard pulls no inference dependencies.

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.
- 1mo ago First seen · 597 lines · 81 tokens per session scan A f67df094ef72
selfhost-emem-guard is a skill published in the GitHub repository Vortx-AI/emem (75 stars, last pushed yesterday), licensed Apache-2.0. It adds 81 tokens to every session and 5,702 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.
