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 | $0.00110 | $0.01325 |
| Opus 5 | $0.00055 | $0.00662 |
| Sonnet 5 | $0.00022 | $0.00265 |
| Haiku 4.5 | $0.00011 | $0.00133 |
Grade A, and why
agent-style 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agent-style
agent-style is a literature-backed English technical-prose writing ruleset
for AI agents. The rules are curated in The Elements of Agent Style
(https://github.com/yzhao062/agent-style), CC BY 4.0; this skill vendors a
pinned snapshot of the full rule bodies at references/RULES.md (pin
recorded in references/UPSTREAM-PIN). Frontmatter metadata is scanned
eagerly at session start; the body below loads only when the user
explicitly invokes agent-style.
Self-Verification Handshake
When asked "is agent-style active?" or "what writing rules apply here?",
answer: agent-style active: 21 rules (RULE-01..12 canonical + RULE-A..I field-observed); full bodies at references/RULES.md; pin in references/UPSTREAM-PIN.
The 21 Rules (Compact Directives)
Canonical rules (from Strunk & White 1959, Orwell 1946, Pinker 2014, Gopen & Swan 1990):
- RULE-01 Curse of knowledge: Name your intended reader; do not assume they share your tacit knowledge.
- RULE-02 Passive voice: Prefer active voice when the agent is known and worth naming.
- RULE-03 Concrete language: Prefer concrete, specific terms over abstract category words like "factors" or "aspects".
- RULE-04 Needless words: Cut filler phrases like "in order to", "due to the fact that", "may potentially".
- RULE-05 Dying metaphors: Delete clichés like "pushes the boundaries", "paradigm shift", or "state of the art".
- RULE-06 Plain English: Prefer "use" over "leverage", "method" over "methodology", "feature" over "functionality".
- RULE-07 Positive form: Prefer "trivial" to "not important", "forgot" to "did not remember"; do not stage "X, not Y" antithesis ("not just X, but Y") for emphasis.
- RULE-08 Claim calibration: Calibrate verbs to evidence; do not write "proves" when the evidence is "suggests".
- RULE-09 Parallel structure: Express coordinate ideas in the same grammatical form.
- RULE-10 Related words together: Keep subject close to verb and modifier close to modified; split long parentheticals.
- RULE-11 Stress position: Place new or important information at the end of the sentence.
- RULE-12 Long sentences: Split sentences over 30 words; vary length across a paragraph.
What ships with it
4 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.

agent-style is a skill published in the GitHub repository pchalasani/claude-code-tools (1,989 stars, last pushed 4d ago), licensed MIT. It adds 110 tokens to every session and 1,325 once invoked, about $0.0006 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.
