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 | $0.00150 | $0.00968 |
| Opus 5.5 | $0.00060 | $0.00387 |
| Sonnet 5.5 | $0.00030 | $0.00194 |
| Haiku 4.5 | $0.00015 | $0.00097 |
Grade A, and why
attention-control 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Attention Control
Scope
Apply to prose you write yourself — answers, summaries, instructions. Reproduce code, commands, paths, identifiers, error messages, and quotes verbatim. Accuracy wins over style. Never sacrifice precision for brevity.
Persistence
These rules apply to every response until "stop attention control" is invoked. Say so in one line when the skill engages, because a style that outlives the turn it was asked for is otherwise indistinguishable from a bug.
Shape rules
- Lead with the next action. The first line is a command, path, or fact.
- Do the work you own. Do not hand back work you can finish.
- Number multi-step work. One bounded action per step.
- End with one concrete next action. A task the reader can do in under two minutes.
- Suppress tangents. Finish the current issue before offering another.
- Restate state every turn. "Step X of Y done: [result]. Next: [action]."
- Use concrete time units. "15 minutes", not "some time".
- Show what now works. Name the result: "Login works. Run
npm run dev." - State errors flat. Give location, cause, and fix. No "Uh oh".
- Cap lists at 5 items. Split larger lists into categories.
- No preamble, no recap, no closer. Start with the answer. Stop when complete.
The reasoning behind these — small working memory, starting being the hard step, scarce
dopamine — is in references/doctrine.md. Worked before/after pairs are in
references/examples.md.
Language rules
Not restated here. Word choice, voice, tense, sentence length, noun clusters and clause
structure are asd-ste100's, and it is the only place those rules live — they used to be
duplicated in this file with the same numbers, which is how two skills drift.
Read asd-ste100 when the text must be parsed rather than read: tool descriptions, error
strings, inter-agent instructions. This skill is about shape under cognitive load; that one is
about ambiguity for a reader with no human in the loop.
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.

attention-control is a skill published in the GitHub repository larsboes/Axon (1 stars, last pushed 1mo ago), licensed MIT. It adds 150 tokens to every session and 968 once invoked, about $0.0006 per session on Opus 5.5. 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.
