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 | $0.00101 | $0.02972 |
| Opus 5 | $0.00051 | $0.01486 |
| Sonnet 5 | $0.00020 | $0.00594 |
| Haiku 4.5 | $0.00010 | $0.00297 |
Grade A, and why
nobrainer-writing scanned grade A with 1 finding 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 7d 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.

NoBrainer Writing
Produce high-signal prose that helps a specific reader understand, decide or act. Treat the Pareto idea as a direction: preserve nearly all decision-relevant value while using far fewer words. It is not permission to remove evidence, conditions or nuance merely to hit an arbitrary ratio.
The protocol, field names and examples in this public skill are written in English. Match the requested output language; when English is requested, use plain, idiomatic English rather than a literal translation.
This skill owns prose quality. nobrainer-research owns missing or current
external facts, nobrainer-decide owns consequential choices, and
nobrainer-build owns behavioral code changes and repository integration. A
small text-only edit can stay here. Do not invoke this skill for a one-sentence
answer that is already clear, specific and complete.
Use BRIEF for a short actionable artifact: a comment, bug report, feature
issue, user story, status update or one clear request. It is a mode of this
skill, not a new skill. Read references/brief-artifacts.md
for the matching shape and examples before drafting.
Read references/research.md only when changing this protocol, auditing its rationale or comparing another writing method. Ordinary writing runs should not spend context on the research record.
Choose one mode
DRAFT: create prose from an established brief and verified source material.COMPRESS: shorten existing prose while preserving its material meaning.REWRITE: improve clarity, structure, voice and naturalness without changing the factual contract.REVIEW: identify only material prose defects and propose the smallest useful correction; do not rewrite merely to express a preference.BRIEF: create or compress one short actionable artifact. Choose exactly one shape from the reference:COMMENT,BUG,ISSUE,USER_STORYorREQUEST.
If the user did not name a mode, infer the smallest one that satisfies the
request. A request to "humanize" means REWRITE, not detector evasion or the
injection of fake mistakes.
What ships with it
3 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.

nobrainer-writing is a skill published in the GitHub repository nobrainer-tech/nobrainer-tech-skills (5 stars, last pushed 6d ago), licensed MIT. It adds 101 tokens to every session and 2,972 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
