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 | $0.00063 | $0.00303 |
| Opus 5 | $0.00032 | $0.00151 |
| Sonnet 5 | $0.00013 | $0.00061 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
tell-dont-ask 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 12d 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
Tell, Don't Ask
Tell the object what you want done; do not ask for its state and make the decision elsewhere.
Workflow
-
Find code that gets state, branches on it, then updates or commands the same object.
-
Name the intention behind the external decision.
-
Move that behavior to the object that owns the state.
-
Replace getters with intention-revealing methods where possible.
-
Keep DTO, serialization, logging, and UI projection exceptions explicit.
Checks
-
Getter plus
ifplus setter is a strong smell. -
Feature Envy means behavior is closer to another object's data than its own.
-
Avoid adding anemic pass-through methods; move real decisions.
Reference
Read references/patterns.md for refactoring patterns.
Detailed Reference
For non-trivial implementation, review, or refactoring work, read references/details.md before giving final guidance. It contains the detailed rules, examples, smells, and migration notes that do not belong in the short invocation body.
Output
Return the ask pattern, the moved behavior, revised API, and code changes.
What ships with it
2 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.

tell-dont-ask is a skill published in the GitHub repository amadeus-dlc/amadeus (8 stars, last pushed 21d ago), licensed Apache-2.0. It adds 63 tokens to every session and 303 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 2026-08-31.
