OllamaOllama模型管理

When to Use

User needs to install, run, integrate, tune, or debug Ollama for local or self-hosted model workflows. Agent handles smoke tests, model selection, API usage, Modelfile customization, embeddings, RAG fit checks, and safe operations.

Use this instead of generic AI advice when the blocker is specific to local runtime behavior: wrong model tag, broken JSON output, poor retrieval, slow inference, context sizing, GPU fallback, or unsafe remote exposure.

Architecture

Memory lives in ~/ollama/. If ~/ollama/ does not exist, run setup.md. See memory-template.md for structure.

Requirements

• - Local ollama access on the target machine, or permission to guide installation.
• Enough RAM, VRAM, and disk for the exact model and context window being proposed.
• Explicit user approval before exposing Ollama beyond localhost, changing service managers, or deleting model files.
• Exact model tags and runtime facts must be verified with live commands such as ollama list, ollama ps, and ollama show.

Never assume model capabilities, context length, quantization, or GPU usage from memory alone.

Operating Coverage

This skill is for practical Ollama execution, not abstract local-LLM discussion. It covers:

• - local installs on macOS, Linux, and Windows
• CLI workflows for pull, run, copy, show, create, and remove
• REST API usage on http://127.0.0.1:11434/api and OpenAI-compatible usage on INLINECODE17
• hardware-aware model sizing, context tuning, and throughput tradeoffs
• Modelfile-based customization for prompts, parameters, adapters, and reproducible model names
• embeddings and local RAG pipelines where indexing, querying, and retrieval must stay consistent

Data Storage

Keep only durable operational context in ~/ollama/:

• - host facts that materially change advice: OS, GPU class, CPU-only constraints, service manager, remote or local deployment
• approved model tags, copied aliases, quant choices, and context limits that worked in practice
• Modelfile defaults, JSON output patterns, and safe OpenAI-compatible mappings
• embedding model choices, vector dimensions, chunking defaults, and retrieval checks
• recurring failures such as partial pulls, CPU fallback, port conflicts, or broken upgrades

Core Rules

1. Verify the Runtime Before Giving Advice

• - Confirm ollama is installed and reachable before proposing any deeper fix.
• Start with the smallest factual checks: ollama --version, ollama list, ollama ps, and one minimal generation or /api/tags request.
• Treat "it runs" and "it runs correctly" as different states.

2. Pin Exact Model Names and Inspect Them Live

• - Use exact tags, not vague family names, for anything reproducible or production-adjacent.
• Inspect the real model with ollama show or /api/show before claiming context length, quantization, or capabilities.
• Avoid silent drift from floating tags when stability matters.

3. Separate Runtime, Modelfile, and App Prompt Responsibilities

• - Debug local behavior in layers: runtime first, then model definition, then application prompt.
• If output quality changed, check whether SYSTEM, TEMPLATE, or PARAMETER settings in the Modelfile are fighting the app prompt.
• Put durable defaults in a named model, not in ad hoc copy-pasted prompts.

4. Choose Models by Hardware and Latency Budget

• - A model that technically loads but falls back to CPU or swaps memory is not a good fit.
• Use ollama ps to confirm processor split before promising performance.
• Keep separate defaults for chat, coding, extraction, vision, and embeddings instead of forcing one model to do everything.

5. Make API and Structured Output Flows Deterministic

• - Prefer non-streaming responses when the next step needs strict parsing.
• Use format: "json" or a JSON schema, set low temperature, and validate the parsed result before taking downstream actions.
• For OpenAI-compatible clients, verify /v1 assumptions instead of assuming every feature maps 1:1.

6. Treat Embeddings and RAG as a Single System

• - Use the same embedding model for indexing and querying unless you intentionally migrate and re-index.
• Inspect retrieved chunks before blaming the model for weak answers.
• Fix chunking, metadata, top-k, and vector dimensions before increasing prompt size.

7. Treat Remote Access and Upgrades as Operational Changes

• - Do not bind Ollama to non-localhost or open port 11434 without explicit approval and a minimal-risk network plan.
• Record service manager changes, environment variables, and rollback steps before upgrading.
• Protect model storage and disk headroom before large pulls or replacements.

Ollama Traps

• - Using latest everywhere -> upgrades silently change behavior and break reproducibility.
• Testing only with ollama run -> app integration still fails on /api or /v1.
• Assuming slow responses mean "bad model" -> often it is CPU fallback, oversized context, or disk pressure.
• Letting app prompts and Modelfile instructions fight each other -> outputs become inconsistent and hard to debug.
• Re-indexing with one embedding model and querying with another -> retrieval quality collapses without obvious errors.
• Exposing the API on a LAN without auth or scoping -> local convenience becomes a security problem.
• Chasing larger context before fixing retrieval or prompt shape -> memory use rises while answer quality barely improves.

External Endpoints

Use external network access only when the task requires model downloads, official docs lookup, or optional cloud execution explicitly approved by the user.

Endpoint	Data Sent	Purpose
https://ollama.com/*	model identifiers, optional doc queries, and optional cloud API requests	Official docs, library lookups, model pulls managed by the Ollama runtime, and optional cloud execution

No other data is sent externally.

Security & Privacy

Data that leaves your machine:

• - model identifiers and download requests when pulling models through Ollama
• optional prompts and attachments only if the user explicitly chooses https://ollama.com/api instead of local inference
• optional documentation lookups against official Ollama pages

Data that stays local:

• - prompts and outputs served through the local Ollama runtime on the user machine
• durable workflow notes under INLINECODE38
• local Modelfiles, retrieval notes, and performance baselines unless the user exports them

This skill does NOT:

• - expose Ollama remotely without explicit approval
• store OLLAMA_API_KEY or other secrets in skill files
• mix local and cloud execution silently
• invent unsupported model features, GPU behavior, or API compatibility
• recommend remote installers or destructive cleanup without explaining risk first

Trust

By using this skill, model pulls and optional cloud requests may go to Ollama infrastructure when the user explicitly chooses those paths.
Only install if you trust Ollama with that data.

Scope

This skill ONLY:

• - installs, verifies, operates, and troubleshoots Ollama workflows
• helps choose, pin, inspect, and customize models with reproducible patterns
• keeps local memory for host constraints, model defaults, and recurring failure fixes

This skill NEVER:

• - claim that every Ollama model supports the same tools, context, or JSON reliability
• recommend unauthenticated remote exposure as a default
• treat local RAG quality as solved without checking embeddings, chunking, and retrieval results
• modify its own skill files
