What it does
Context Os Basics is an agent skill from jacob-dietle/context-os. Foundation patterns for building context operating systems
Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management. The licence is MIT.
When your agent uses it
- Knowledge Management work in your project
Example prompts
- “/context-os-basics”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 1027e3f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
taste.systems
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Context Os Basics loads about 745 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 352 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md

Context OS Basics
What is a Context OS?
A context operating system is a structured knowledge system where:
- AI compounds intelligence over time (never re-teach)
- Knowledge persists across sessions
- Concepts link to each other (graph, not files)
- Two layers separate reusable knowledge from operational docs
The Two-Layer Architecture
Layer 1: Atomic Knowledge Graph (knowledge_base/)
Individual reusable concepts:
- Technical knowledge
- Business insights
- Methodologies and patterns
Each node:
- Has structured frontmatter (metadata)
- Links to related concepts via [[wiki-links]]
- Follows lifecycle: emergent → validated → canonical
Layer 2: Operational Documents (00_foundation/)
Strategic artifacts that COMPOSE Layer 1:
- Positioning documents
- Messaging frameworks
- Process documentation
Key principle: Operational docs REFERENCE atomic concepts, they don't redefine them.
Constitutional Documents
taxonomy.yaml
Defines blessed tags for your system:
- Domains (technical, business, methodology)
- Node types (concept, pattern, case-study)
- Status values (emergent, validated, canonical)
- Your custom topic library
Start small. Add tags only after 3+ nodes demonstrate need.
ontology.yaml
Defines how concepts relate:
- Relationship types (enables, supports, implements)
- Linking requirements (minimum links per node)
- Quality thresholds
Evidence-Based Attribution
Every claim needs a source:
- [VERIFIED: file:line] - Direct evidence
- [INFERRED: logic] - Deduced from evidence
- [UNVERIFIABLE] - Cannot confirm (be honest)
Quality standard: If you can't cite a source, don't claim it.
The 4-Phase Framework (Summary)
- Reconnaissance - Understand domain and requirements
- Architecture - Design two-layer structure
- Construction - Build knowledge graph and ops docs
- Validation - Test and document system

Key Anti-Patterns
1. One Continuous Thread
Problem: Single long conversation without writing to files Fix: Write intermediate results to files, preserve attribution chains
2. Context Explosion
Problem: "Need to read all files to answer this" Fix: Use synthesis docs (5% of content answers 95% of questions)
3. Vague Attribution
Problem: "Many customers want this" (no source) Fix: Quantify everything: "14 of 166 (8.4%)" not "many"
The 3-5 Sample Rule
Never automate without sampling first:
- Run broad search
- Sample 3-5 results with context
- Validate patterns are accurate
- Refine and scale
Advanced Patterns (Not Covered Here)
For complex implementations:
- Chief of Staff orchestration
- Forcing functions and calibration
- Team governance patterns
- Enterprise taxonomy design
- Multi-agent coordination
These require customization for your specific context. Learn more: https://taste.systems
