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 | $0.00041 | $0.01896 |
| Opus 5 | $0.00020 | $0.00948 |
| Sonnet 5 | $0.00008 | $0.00379 |
| Haiku 4.5 | $0.00004 | $0.00190 |
Grade A, and why
eve-agent-native-design 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.

Agent-Native Design for Eve Horizon
Build applications where agents are first-class citizens — not afterthoughts.
When to Use
Load this skill when:
- Designing a new application or API on Eve
- Evaluating whether an existing app is agent-friendly
- Adding features that agents should be able to use
- Deciding between putting logic in code vs. in prompts
- Choosing how to handle inter-agent communication
The Four Principles
1. Parity — Agents Can Do Everything Users Can
Every user action must have an agent-equivalent path.
On Eve: The CLI IS the parity layer. If a user can do it through eve ..., an agent can too. When building your app, apply the same principle:
| Check | How |
|---|---|
| Can agents create/read/update/delete every entity? | Map UI actions to CLI/API equivalents |
| Are there UI-only workflows? | Expose them as API endpoints or CLI commands |
| Can agents discover what's available? | Provide list operations for every entity type |
CRUD Completeness: For every entity in your app, verify agents have Create, Read, Update, and Delete paths. Missing any one breaks parity.
2. Granularity — Atomic Primitives, Not Bundled Logic
Features emerge from agent loops, not monolithic tools.
Wrong: deploy_and_monitor(app) — bundles judgment into code
Wrong: classify_and_organize_files(files) — agent should decide classification
Right: eve build create, eve build run, eve env deploy, eve job follow — agent decides the sequence
On Eve: The manifest defines WHAT (services, pipelines), the agent decides HOW and WHEN to compose them.
Design test: To change behavior, do you edit prose (prompts/skills) or refactor code? If code — your tools aren't atomic enough.
3. Composability — New Features = New Prompts
When tools are atomic and parity exists, you add capabilities by writing prompts, not code.
Eve example: The eve-pipelines-workflows skill adds pipeline composition capability. No new CLI commands needed — the skill teaches agents to compose existing eve pipeline and eve workflow commands.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

eve-agent-native-design is a skill published in the GitHub repository Incept5/eve-skillpacks (0 stars, last pushed 2mo ago), licensed MIT. It adds 41 tokens to every session and 1,896 once invoked, about $0.0002 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 2026-08-31.
