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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00030 | $0.00226 |
| Opus 5 | $0.00015 | $0.00113 |
| Sonnet 5 | $0.00006 | $0.00045 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
dayan-agent-designer 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
Dayan Agent Designer
Use this Skill when designing an agent or multi-agent system. Start with the least complex viable form:
rule → pipeline → single agent → supervisor and specialists → parallel workers and reviewer
Every escalation needs evidence that the simpler form fails.
Design contract
- Task surface: objective, untrusted inputs, output schema, completion and stop conditions.
- Roles: one responsibility, one bounded input, one output contract, explicit exclusions, and a unique name.
- Tools: minimum permissions, read/write boundaries, external effects, and credential handling.
- State: one owner for each mutable state; no invisible shared memory.
- Coordination: dependencies, concurrency limits, timeout, retry, cancellation, and conflict resolution.
- Evaluation: accepted fixture, rejected fixture, adversarial case, cost/latency budget, and human takeover point.
Do not deploy or spawn agents unless the user separately authorizes execution. A design is not runtime evidence.
What ships with it
3 files 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.

dayan-agent-designer is a skill published in the GitHub repository Kosmoray/dayan-agent-skills (4 stars, last pushed 24d ago), licensed MIT. It adds 30 tokens to every session and 226 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.
