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 | $0.00080 | $0.01010 |
| Opus 5 | $0.00040 | $0.00505 |
| Sonnet 5 | $0.00016 | $0.00202 |
| Haiku 4.5 | $0.00008 | $0.00101 |
Grade A, and why
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 yesterday.
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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Second Opinion Skill
Proactively suggest getting another LLM's perspective when the situation warrants it.
Trigger Conditions
Suggest a second opinion when you detect:
1. Architectural Decisions
- Choosing between design patterns (e.g., repository vs service layer)
- Database schema design decisions
- API design choices (REST vs GraphQL, versioning strategy)
- Service decomposition (monolith vs microservices)
- State management approaches
2. Complex Trade-offs
- Performance vs. readability
- Flexibility vs. simplicity
- DRY vs. explicit code
- Build vs. buy decisions
- Consistency vs. availability trade-offs
3. Critical Code Reviews
- Security-sensitive code (authentication, authorization, crypto)
- Performance-critical paths
- Complex algorithms or data structures
- Code handling financial transactions or PII
- Concurrency and threading logic
4. Explicit Requests (trigger words)
- "another perspective"
- "second opinion"
- "sanity check"
- "what do you think"
- "am I on the right track"
- "does this make sense"
- "is this a good approach"
How to Suggest
A second opinion is most valuable from a different model family than the one that wrote the code. Bind the active assistant surface before suggesting an invocation.
Gemini CLI
Offer only commands packaged by the active gopher-ai-llm-tools extension:
/ollama <specific question>asks an installed Ollama model. Treat it as local only after verifying thatOLLAMA_HOSTresolves to a loopback host./llm-compare <specific question>compares the available providers.
If a bare command conflicts with a user or project command, use the
extension-prefixed form shown by /commands list, such as
/gopher-ai-llm-tools.ollama. Never suggest command syntax from another
assistant surface on Gemini CLI.
Codex
Offer only installed Codex skills:
$llm-tools:gemini <specific question>asks Google Gemini. Explain that the prompt goes to a cloud provider and that adding code or repository context requires explicit confirmation.$llm-tools:ollama <specific question>asks an installed Ollama model. Its privacy boundary depends on the configured Ollama endpoint; the provider skill verifies loopback destinations or confirms a non-loopback transfer.
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.

second-opinion is a skill published in the GitHub repository gopherguides/gopher-ai (21 stars, last pushed today), licensed MIT. It adds 80 tokens to every session and 1,010 once invoked, about $0.0004 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.
