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.

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 | $0.00063 | $0.00505 |
| Opus 5 | $0.00032 | $0.00253 |
| Sonnet 5 | $0.00013 | $0.00101 |
| Haiku 4.5 | $0.00006 | $0.00051 |
Grade A, and why
agy-second-opinion 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 8d 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.
What it actually says
Second Opinions via agy
Overview
agy exposes non-Anthropic models (Gemini Pro/Flash, GPT-OSS — see
agy_list_models). A cross-family review catches blind spots that every model
in one family shares. Use agy_ask to get a written opinion, then report it
back with attribution.
Recipe
- Give it the context. Put the relevant files' directory in
add_dirand name each file by absolute path in the prompt. For a diff or plan that isn't a file, paste it into the prompt verbatim. - Call
agy_ask:model: an exact string fromagy_list_models.Gemini 3.1 Pro (High)for depth,Gemini 3.5 Flash (High)for speed. Skip the Claude entries — same family is not a second opinion.prompt: frame it as review, not work:You are giving a written second opinion — do NOT edit any files. <question, with context paths or pasted content>. End with a verdict (agree/disagree) and your top 3 concerns.timeout_ms:600000
- Report with attribution. Separate agy's points from your own, deliver its disagreements verbatim rather than softened, and state where you concur or push back.
To debate a point, call agy_ask again with continue_conversation: true.
Traps
| Symptom | Cause | Fix |
|---|---|---|
| agy starts editing files | It's an agent; prompt read like a task | Lead with "written second opinion — do NOT edit any files" |
| Opinion is generic boilerplate | agy never saw the actual code/plan | add_dir + absolute paths, or paste the content into the prompt |
| "model not found" | Guessed model name | Run agy_list_models, copy the exact string |
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.

agy-second-opinion is a skill published in the GitHub repository yinjs/agyenvoy (1 stars, last pushed 1mo ago), licensed MIT. It adds 63 tokens to every session and 505 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 2026-08-31.
