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.

What it costs to keep this loaded
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 | $0.00066 | $0.01739 |
| Opus 5 | $0.00033 | $0.00870 |
| Sonnet 5 | $0.00013 | $0.00348 |
| Haiku 4.5 | $0.00007 | $0.00174 |
Grade A, and why
ase-meta-config 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 9d 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.

$ARGUMENTS
Procedure
-
Determine Operation:
-
Set , with any leading and trailing whitespace stripped. Split into whitespace-separated tokens, honoring single and double quotes (a quoted token is one token, with its surrounding quotes removed). Set to the first token, lower-cased, and to the list of the remaining tokens. If is empty, set (none) and to the empty list. Inherit the always existing from the current context. Do not output anything.
-
Determine the target scope chain:
Do not output anything.
-
You MUST NOT use
Bash,Read,Write,Edit, or any other filesystem-touching tool anywhere in this skill. Every configuration access is performed exclusively through thease_config_*tools of theaseMCP server. Do not output anything.

-
Dispatch Operation:
-
-
If the
entriesarray is empty, output the following : -
Else output the following , where each , , and correspond to one entry of the
entriesarray, in the given order:Key Value Scope <key/><entry-scope/>[...] [...] [...]
-
-
-
If is empty, the key is not set at all. Output the following :
-
Else set to the JSON-decoded and output the following :

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-meta-config is a skill published in the GitHub repository rse/ase (47 stars, last pushed today), licensed Apache-2.0. It adds 66 tokens to every session and 1,739 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.
