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.

SkillSpector: 1 finding, up to high
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 →

Stripping safety caveats hides risk from the user and is a common jailbreak preamble.Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
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 | $0.00189 | $0.02180 |
| Opus 5 | $0.00095 | $0.01090 |
| Sonnet 5 | $0.00038 | $0.00436 |
| Haiku 4.5 | $0.00019 | $0.00218 |
Grade A, and why
adversarial-phoenix-liveview 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 9d 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.

Adversarial Phoenix LiveView Gate
A realtime-UI architecture review gate for Phoenix LiveView — pass/fail: a single blind reviewer subagent judges the work against this gate's rules with an adversarial mandate, and the work passes only when every rule is PASS or N/A. This skill renders verdicts; it never fixes the work.
The rules target one failure mode: LiveView written as a page-controller bolted to a JS framework, instead of what it is — a stateful process rendering change-tracked diffs over a lossy socket. Remounts that destroy state a patch would keep, broadcasts emitted where only one writer fires them, external calls that freeze the whole view, template constructs that silently disable change tracking, collections that grow per-socket memory without bound, events trusted because the button was hidden, and interactions designed against localhost latency. These all compile cleanly and demo perfectly; they surface as memory bloat, stale UIs, frozen views, and IDOR reports in production. Each rule carries an Evidence of violation paragraph so a reviewer can decide PASS/FAIL/N/A from artifact evidence alone. Sibling gates: adversarial-beam judges message-delivery semantics, adversarial-elixir judges paradigm fit — run all three for full coverage of substantial Phoenix work.
When to Apply
- A Phoenix LiveView feature — live views, live components, HEEx templates, PubSub-driven UI updates, presence, infinite scroll — is about to merge and needs an objective PASS/FAIL on its realtime-UI architecture.
- An agent (Claude, Codex) authored LiveView code and you want an independent check that it did not fake realtime correctness — controller habits, unscoped topics, unbounded assigns, unauthorized event handlers, zero-latency assumptions.
- A LiveView app is being prepared for real traffic and the localhost-era assumptions (no latency, one node, small data, trusted clients) need to be surfaced as verdicts.
- A production incident (memory bloat, frozen view, IDOR, stale UI) was fixed at one site and you want the same class hunted across the affected area.

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.

adversarial-phoenix-liveview is a skill published in the GitHub repository pproenca/dot-skills (205 stars, last pushed 24d ago), licensed MIT. It adds 189 tokens to every session and 2,180 once invoked, about $0.0009 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 2026-08-30.
