Pydantic Deep Agents is a self-hosted terminal AI assistant and Python framework for building coding, research, and other AI agents. It gives agents tools such as file access, shell commands, planning, memory, sub-agents, sandboxed execution, and MCP connections, and supports different models.
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.

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 | $0.00011 | $0.00311 |
| Opus 5.5 | $0.00004 | $0.00124 |
| Sonnet 5.5 | $0.00002 | $0.00062 |
| Haiku 4.5 | $0.00001 | $0.00031 |
Grade A, and why
skill-creator 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 1mo 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
Skill Creator
Create a new skill by generating a SKILL.md file with YAML frontmatter.
Steps
- Identify the task pattern the user wants to capture as a skill
- Write clear, specific instructions that an AI agent can follow
- Create a directory with this structure:
my-skill/
├── SKILL.md # Instructions + frontmatter
├── template.md # (optional) Template files
└── example.py # (optional) Example scripts
- The SKILL.md must have this format:
---
name: skill-name
description: "Brief description of what this skill does"
tags: [category1, category2]
version: "1.0.0"
---
# Skill Name
## Purpose
What this skill accomplishes.
## Instructions
Step-by-step instructions for the agent.
## Examples
Concrete examples of input/output.
Guidelines
- Name: lowercase with hyphens (e.g.,
api-client-generator) - Description: one sentence, starts with a verb
- Instructions: specific enough that another agent can execute without context
- Include edge cases and error handling guidance
- Add examples showing expected input and output
- Place resources (templates, schemas) as separate files next to SKILL.md
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.

skill-creator is a skill published in the GitHub repository vstorm-co/pydantic-deepagents (1,105 stars, last pushed 3d ago), licensed MIT. It adds 11 tokens to every session and 311 once invoked, about $0.0000 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 2026-08-30.

Get Unstuck
Pause, surface the current plan + open questions, and suggest the next concrete step so the agent (or operator) can recover from a deadlock or analysis paralysis.
