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 | $0.00134 | $0.01572 |
| Opus 5 | $0.00067 | $0.00786 |
| Sonnet 5 | $0.00027 | $0.00314 |
| Haiku 4.5 | $0.00013 | $0.00157 |
Grade A, and why
clarity-editing 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 3d 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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clarity Editing
Good writing is rewriting. First draft: get the thought on the page. Second draft: make the thought disappear behind the sentence. This skill is the second draft.
The four editing passes
Run in order. Each pass targets one problem.
Pass 1 — compress
Cut every word that does not carry its weight. Typical savings: 20-40%.
| Cut | Keep |
|---|---|
| "in order to" | "to" |
| "due to the fact that" | "because" |
| "at this point in time" | "now" |
| "a number of" | "several" / "many" / a number |
| "is able to" | "can" |
| "make a decision" | "decide" |
| "in the event that" | "if" |
| "on a daily basis" | "daily" |
Sentence-level compression: if a sentence is over 25 words, look for a comma that could be a period.
Pass 2 — active voice
Passive voice hides the actor and adds words.
| Passive | Active |
|---|---|
| "A decision was made by the team to defer the launch." | "The team deferred the launch." |
| "It has been observed that users are churning." | "Users are churning." |
| "The bug was caused by the cache layer." | "The cache layer caused the bug." |
Exceptions — use passive when:
- The actor is irrelevant ("the package was delivered").
- The actor is unknown.
- You deliberately de-emphasize the actor (accountability writing).
Default: active. Every passive sentence should be deliberate.
Pass 3 — strip hedges
Hedges and weasel words sap authority.
| Hedge | Strip to |
|---|---|
| "I think that it might be a good idea to" | "" (delete) or "We should" |
| "It seems like there may be some concern that" | "Users worry that" |
| "We should probably consider possibly doing" | "We should do" |
| "In our opinion, it's arguably" | "" (delete) |
| "Kind of" / "sort of" / "basically" | delete |
If you are genuinely uncertain, say so with a number ("60% confidence") or a named unknown, not a pile of hedges.

Pass 4 — fix nominalizations
What ships with it
5 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.

clarity-editing is a skill published in the GitHub repository viktorbezdek/skillstack (11 stars, last pushed 2mo ago), licensed MIT. It adds 134 tokens to every session and 1,572 once invoked, about $0.0007 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.
