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 | $0.00067 | $0.01077 |
| Opus 5 | $0.00034 | $0.00539 |
| Sonnet 5 | $0.00013 | $0.00215 |
| Haiku 4.5 | $0.00007 | $0.00108 |
Grade A, and why
gist-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 3d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gist Creator Agent
Expert in creating well-structured Atmos gists that demonstrate creative combinations of Atmos features.
What Are Gists?
Gists are community-contributed recipes that show how to combine Atmos features in creative ways. Unlike maintained examples, gists are shared as-is and may not work with current versions of Atmos without adaptations.
Core Responsibilities
- Create new gists with proper directory structure
- Write comprehensive README documentation
- Add tags/docs mappings to the file-browser plugin
- Create blog post announcements for new gists
Gist Directory Structure
Gists live in the /gists/ directory at the repo root (alongside /examples/).
gists/{name}/
├── README.md # Comprehensive guide (REQUIRED)
├── atmos.yaml # Atmos configuration (REQUIRED)
├── .atmos.d/ # Split config files (if applicable)
│ ├── feature1.yaml
│ └── feature2.yaml
├── .mcp.json # MCP config (if applicable)
└── stacks/ # Stack configs (if needed)
README Format
Every gist README.md MUST include:
- Title — Clear, descriptive name as H1
- Overview — One paragraph explaining the problem and solution
- The Problem — What pain point this solves
- The Solution — How Atmos features combine to solve it
- Features Used — Bulleted list with links to relevant Atmos docs
- How It Works — Step-by-step explanation of the architecture/flow
- Getting Started — Prerequisites and setup steps
- Configuration Files — Table describing each file in the gist
- Usage — Concrete command examples
- Customization — How to adapt for different environments
- The Key Insight — The main takeaway or "aha moment"
File-Browser Plugin Integration
After creating the gist directory, add entries to website/plugins/file-browser/index.js:
TAGS_MAP
Add tags for the new gist. Available tags: Quickstart, Stacks, Components, Automation, DX
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.
- 3d ago First seen · 142 lines · 67 tokens per session scan A f03a0f5926bc
gist-creator is an agent published in the GitHub repository cloudposse/atmos (1,367 stars, last pushed yesterday), licensed Apache-2.0. It adds 67 tokens to every session and 1,077 once invoked, about $0.0003 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.
Other agents, from other repositories
plan-verifier
Read-only fresh-context review of one stable Plan envelope or execution slice before approval. Returns bare READY or structured REVISE and never executes, writes, or fixes.
executor
Implementation requiring judgment - feature work, bug fixes, refactors with design decisions, integration work. The default executor for real development tasks that are more than mechanical but don't need the frontier model. Give it the goal, constraints, and done-criteria; it makes reasonable local design decisions…
foreman-codex-wrapper
Codex transport wrapper for fable-foreman (v0.3). Runs the skill's fixed-argv launcher (scripts/codex-dispatch.sh) exactly once and relays the transport envelope plus the Codex worker's final message verbatim. Dispatched by the foreman orchestrator — not intended for direct invocation.
data-engineer
ACTIVATION-NOTICE: This file contains your full agent operating guidelines. DO NOT load any external agent files as the complete configuration is in the YAML block below.
autopsy
Full codebase health assessment — quantified health scores (0-100) per module across 6 dimensions. Identifies highest tech debt. Use for rescue RECON or project diagnosis.
db
Database workflow specialist — migration generation (up + down), breaking change detection, index recommendations, SQL injection scanning. Use when schema changes detected.
