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 5.1 | $0.00027 | $0.00490 |
| Opus 5 | $0.00014 | $0.00245 |
| Sonnet 5 | $0.00005 | $0.00098 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade A, and why
skills-and-capabilities 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 11d 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
Skills and Extension Capabilities
Use this doc when you need to decide whether something should be a skill, a doc, an instruction file, an imported plugin package, or an extension.
Fast split
- instruction file — standing behavior and policy
- doc — reusable knowledge
- skill — reusable workflow
- extension — Neon Pilot capability package implemented directly or wrapping another package format
- plugin — external ecosystem package format imported through an extension wrapper
Skills
Skills are reusable workflow packages.
Shared contract:
<knowledge-root>/skills/<skill>/SKILL.md
Use a skill when you want:
- a named repeatable workflow
- reusable procedural guidance
- supporting files bundled with the workflow
Extensions
Extensions change what Neon Pilot can do.
Examples in this repo:
knowledge-baseweb-toolsdaemon-run-orchestration-promptcodex-profile
Use an extension when the change requires code and runtime integration, not just new instructions.
Use an imported plugin/package wrapper when the capability already exists in another agent ecosystem, such as Codex, Claude, or MCP, and should be managed through Neon Pilot's extension registry.
What to edit when you want to change behavior
- change
AGENTS.mdor selected instruction files for policy and standing behavior - add or edit a doc for reusable knowledge
- add or edit a skill for reusable workflow
- add or edit an extension when the runtime itself needs new behavior
Practical rule
If markdown is enough, do not start with an extension.
Reach for an extension only when you need new tools, UI, event handling, runtime hooks, or permission behavior.

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.

skills-and-capabilities is a skill published in the GitHub repository patleeman/neon-pilot (23 stars, last pushed 1mo ago), licensed MIT. It adds 27 tokens to every session and 490 once invoked, about $0.0001 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.
