A consultation mode that asks several AI models to examine a difficult question and combines their views into a structured answer. It uses different discussion styles for coding, research, brainstorming, quick questions, and other situations.

Use it when you want a second opinion, a deep review, a council discussion, or help thinking through a high-stakes decision.

It gives another way to examine important or uncertain decisions instead of relying on one model's first answer.

Token cost

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	$0.00053	$0.08485
Opus 5.5	$0.00021	$0.03394
Sonnet 5.5	$0.00011	$0.01697
Haiku 4.5	$0.00005	$0.00848

Security

Grade A, and why

nestor 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Nestor

Nestor is a named consultation mode for multi-model deliberation. When the user or the session needs a multi-model council on a hard decision, invoke this skill to run the deliberation through a disciplined protocol: self-contained question formulation, routing, council execution, synthesis, and structured presentation back to the user.

This skill is self-contained. The core protocol — triggers, router, envelopes, presentation, kill criteria — lives in this file. Detailed deliberation mechanics (preset model rosters, fallback chains, the pal.consensus step-by-step workflow, stance semantics with the Gemini Flip empirical finding, and the deliberative stage-2 cross-critique template) live in references/ within this skill and are loaded on demand:

references/router-cases.md — eleven acceptance cases for routing, explicit field inheritance and the invariant check
references/presets.md — model rosters for arch / code / research / brainstorm / quick plus per-vendor fallback chains
references/consensus-execution.md — mcp__pal__consensus step-by-step workflow, continuation_id handling, stepping discipline
references/stances-and-gemini-flip.md — stance semantics (for / against / neutral as roleplay-not-belief) and the Gemini Flip finding
references/deliberative-stage-2.md — cross-critique protocol, the verbatim critique prompt template, anti-patterns
references/setup.md — what the host must provide: pal install, process topology, metadata sink, background delivery, redeploy
references/openrouter-models.example.json — pal model registry for every preset and fallback id (context windows); a roster refresh updates it too, tests/test_doc_links.py checks the coverage

When to invoke

Invoke this skill when:

The user explicitly addresses Nestor or asks for other models' opinion — what the skill loader matches through the description above. Phrases of this kind: "ask Nestor", "go to Nestor", "сходи к Нестору", "спроси Нестора", "Nestor, …" followed by a question, "третье мнение", "second opinion", "что думает совет", "what does the council think", "прогони через совет", "спросить модели", "что думают другие" — and anything equivalent in meaning. Mode words inside such a request ("глубокий разбор" / "deliberate" → deliberative) and a named preset ("Nestor quick:", "Nestor brainstorm") steer the router (rule 0; "quick check" alone is rule 5's shape wording, not a preset — see §The router); on their own they are not an invocation. Importance or urgency markers — "критично", "важное решение", "high stakes", "critical decision", "think carefully" — are not instructions to convene the council: they are context for the implicit decision below, and must never be recorded in run metadata as an explicit trigger the user did not give.

Changes

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.

nestor is a skill published in the GitHub repository dkushnikov/nestor-plugin (2 stars, last pushed 6d ago), licensed MIT. It adds 53 tokens to every session and 8,485 once invoked, about $0.0002 per session on Opus 5.5. 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.
