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 | $0.00309 |
| Opus 5 | $0.00034 | $0.00154 |
| Sonnet 5 | $0.00013 | $0.00062 |
| Haiku 4.5 | $0.00007 | $0.00031 |
Grade A, and why
parse-dont-validate 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 5d 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
Parse, Don't Validate
Do not merely check data and then throw the proof away. Parse it into a type that carries the proof.
Workflow
-
Find validators that return
bool,void, or throw while leaving the original untyped value in circulation. -
Define a target type whose construction proves the invariant.
-
Replace validation calls with parser or smart-constructor calls that return
Result,Either, option, or exceptions as appropriate for the language. -
Change downstream APIs to accept the parsed type.
-
Remove redundant re-validation.
Checks
-
A parsed type should make invalid states unrepresentable.
-
Keep boundary parsing near input edges.
-
Preserve error detail for users and logs.
Reference
Read references/patterns.md for language 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 current validation leak, parsed type design, API changes, and migration steps.
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.

parse-dont-validate is a skill published in the GitHub repository amadeus-dlc/amadeus (8 stars, last pushed 14d ago), licensed Apache-2.0. It adds 67 tokens to every session and 309 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.
