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 30 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.

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 | $0.00116 | $0.02811 |
| Opus 5 | $0.00058 | $0.01406 |
| Sonnet 5 | $0.00023 | $0.00562 |
| Haiku 4.5 | $0.00012 | $0.00281 |
Grade A, and why
sssf-sandbox-orchestrator 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Dropping to `ssh <vm>.exe.xyz '...'` or `curl` to **inspect** is fine and expected — that is what How it starts
The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SSSF Sandbox Orchestrator
Drives the out-of-sandbox half of this repo: the sbx namespace under just/sandbox/ that
take a blank exe.dev VM to a health-checked, running factory in ~10s, run work inside it, expose it
to a browser, and — only when a human says so — tear it down.
The one governing principle: THIN SKILL, FAT RECIPES
Every action you take should be a just command a human could type. The recipes hold the
knowledge; this skill holds the judgment about which one to run and how to read the result.
- Dropping to
ssh <vm>.exe.xyz '...'orcurlto inspect is fine and expected — that is whatjust sbx run cmd <id> '<cmd>'exists for, and reading a log or a table needs no ceremony. - Re-implementing what a recipe already does is not. Never hand-roll a key mint, a revoke, an
ssh exe.dev new, ashare port, or a detachednohuplaunch. Those encode measured facts (mint order, the revocation gate, the proxy retarget, the three detachment pieces) and a hand-rolled version drops one of them silently. - If a recipe is wrong, fix the recipe and say so. Do not route around it.
Dependencies
This skill references /sssf and /sandbox-exe-dev rather than duplicating them. /sssf owns
the ADW roster, the handoff contract and the trace-db schema; /sandbox-exe-dev owns the exe.dev
CLI surface. Both move without asking us, and a copy pasted here would be a second source of truth
that goes wrong quietly — a stale model id, a renamed flag. Read them; do not quote them.
Preflight is one command. Run it before the first phase; any failure means report and stop, never work around a missing prerequisite by hand.
just sbx manage doctor
It checks all six in one pass: ssh exe.dev reachable, OPENROUTER_PROVISIONING_KEY set (never
printed), the run-record helper runs, the provisioner is executable,
the models template carries full four-field rate blocks, and the adw layer resolves. Green ends
with sbx doctor: OK.
What ships with it
13 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

sssf-sandbox-orchestrator is a skill published in the GitHub repository disler/inkwell-agent-sandboxes-and-software-factory (154 stars, last pushed 1mo ago), licensed MIT. It adds 116 tokens to every session and 2,811 once invoked, about $0.0006 per session on Opus 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.
