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 | $0.00019 | $0.01438 |
| Opus 5 | $0.00010 | $0.00719 |
| Sonnet 5 | $0.00004 | $0.00288 |
| Haiku 4.5 | $0.00002 | $0.00144 |
Grade A, and why
ase-task-list 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 4d 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 the effective state set , i.e., the lifecycle states a task plan has to be in to be listed at all. For this, parse and as comma-separated token lists, silently dropping the
nonesentinel and any empty token. If a token is not one of the eightStatus:valuesDRAFTED,REJECTED,APPROVED,DEFERRED,STARTED,BLOCKED,COMPLETED, orCANCELLED, only output the following and then STOP processing the entire current skill:Otherwise set to all eight states if both lists are empty, to the include list if only it is non-empty, to all eight minus the exclude list if only it is non-empty, and to the include list minus the exclude list if both are non-empty. If the resulting is empty, only output the following and then STOP processing the entire current skill:
Directly after this error , and before stopping, give the corrective hint by expanding the following (which, depending on the configured , may expand into nothing and hence emit no output at all):
-
Call the
ase_task_list(verbose: <getopt-option-verbose/>)tool from theaseMCP server. The result is a structured object with atasksarray where each entry has anidand astatusfield, and -- if istrue-- additionally anmtimefield (formatted asYYYY-MM-DD HH:MM). Drop from thetasksarray every entry whosestatusis not contained in . Do not output anything. -
If the
tasksarray is empty, output the following :Else, dispatch on :
-
If is
true, output the list of tasks with the following , where each , , and correspond to an entry in the task list:Task Id Status Last Modified <status/><mtime/>[...] [...] [...] -
If is
false, output the list of tasks with the following , where each corresponds to an entry in the task list:Task Id [...]
-
-
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-task-list is a skill published in the GitHub repository rse/ase (47 stars, last pushed 6d ago), licensed Apache-2.0. It adds 19 tokens to every session and 1,438 once invoked, about $0.0001 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.
