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 | $0.00051 | $0.01292 |
| Opus 5 | $0.00026 | $0.00646 |
| Sonnet 5 | $0.00010 | $0.00258 |
| Haiku 4.5 | $0.00005 | $0.00129 |
Grade A, and why
ase-sync-export 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 3d 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.

Procedure
-
-
Parse as the comma-separated list of
[<format>:]<file>entries, with one ofjson,json5,yaml,toon,html,pdf, ormd, and a project-relative output file path. Trim every parsed entry. Do not output anything. -
Determine the default output by calling the
ase_artifact_name(filename: "index.html", kind: "spec")tool of theaseMCP server and set to the single entry of its returnedname. Do not output anything. -
If any entry in is
-(the standard output sentinel), only output the following and then immediately STOP processing the entire current skill: -
Report the resolved outputs with the following :
-
-
-
Call the
ase_specbook_lint()tool of theaseMCP server once and read its returneddiagnosticsarray of{ file, line, column, message }objects. Do not output anything. -
Only output the following (listing one bullet line per diagnostic), give the closing hint by expanding the
<ase-tpl-hint/>below it, and then immediately STOP processing the entire current skill:<file/>:<line/>:<column/>: [...]
-
-
-
For each in , call the
ase_specbook_export(output: "<output/>")tool of theaseMCP server, which infers the format from the[<format>:]<file>entry, writes the rendering to the file, and returns a confirmationtextcarrying the written byte size plus anoticesarray of environment notices. Set to the distinct notices of all calls. Do not output anything. -
Report the exported files with the following , listing one bullet line per written file (with its project-relative path and the format and the byte size):
<file/>: [...]
-
Report the environment notices verbatim with the following , listing one bullet line per notice:
[...]
-
Finally, give the closing hints by expanding the following (which, depending on the configured , may each expand into nothing and hence emit no output at all):
-
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.

ase-sync-export is a skill published in the GitHub repository rse/ase (47 stars, last pushed 5d ago), licensed Apache-2.0. It adds 51 tokens to every session and 1,292 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 2026-08-30.

Step-by-step process for validating a Python Foundry hosted agent sample (under python/samples/04-hosting/foundry-hosted-agents/) end to end — running it locally (native runtime and azd ai agent run) and after deploying it to an Azure AI Foundry project with azd. Use this when asked to validate a hosted agent sample.
