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 | $0.00049 | $0.00249 |
| Opus 5 | $0.00024 | $0.00125 |
| Sonnet 5 | $0.00010 | $0.00050 |
| Haiku 4.5 | $0.00005 | $0.00025 |
Grade A, and why
unsummarizable 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 2d 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
Unsummarizable
Write so that removing words removes interesting ideas.
- Cut throat-clearing, repetition, generic framing, and sentences that only summarize nearby sentences.
- Preserve specifics, causal links, examples, distinctions, and necessary qualifications.
- Make every sentence advance the argument; make every paragraph earn its place.
- Test each phrase by removing it. If meaning and insight survive intact, leave it out.
- Keep the result clear. Density is not obscurity, jargon, or compressed grammar.
When revising existing prose, return the tightened version unless the user asks for commentary. Do not merely shorten it: retain its interesting ideas and add precision where vague language was hiding missing thought.

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.

unsummarizable is a skill published in the GitHub repository mrmps/chomsky-stack (7 stars, last pushed 3d ago), licensed MIT. It adds 49 tokens to every session and 249 once invoked, about $0.0002 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.
