A portable set of writing rules for agent-generated prose, plus instructions for installing and checking those rules in a project.

Use it when installing, copying, syncing, or auditing Agent-Style support, or when reviewing text against its bundled rules.

It helps keep agent output consistent with a chosen style and prevents style checks from depending on files that are missing or stored in the wrong place.

agent-style — Skill for Claude Code by tranhieutt

Install

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.

Any agent

npx skills add tranhieutt/software_development_department --skill agent-style

Clone the repo

git clone --depth 1 https://github.com/tranhieutt/software_development_department

Made for: Claude Code.

Per session 55 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 612 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

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	$0.00055	$0.00612
Opus 5	$0.00028	$0.00306
Sonnet 5	$0.00011	$0.00122
Haiku 4.5	$0.00006	$0.00061

Measured 8d ago against content hash 6908f1504fc1, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-07, from the pricing page.

Security

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 8d 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

Agent Style

Portable SDD wrapper for the vendored agent-style v0.3.5 rule pack.

This skill exists so Agent-Style support moves with .claude/skills/ when SDD is applied to another project. It does not enable global writing style, does not edit AGENTS.md or CLAUDE.md, and does not replace style-review.

Bundled Source

Rules: references/RULES.md
Upstream pin: references/UPSTREAM.md
Attribution: references/NOTICE.md
Detector notes: references/rule-detectors.md
Revision prompt: references/revision-prompt.md

Retain references/NOTICE.md when copying or redistributing this skill.

Install Check

When asked whether Agent-Style is available in a target project, verify:

.claude/skills/agent-style/SKILL.md exists.
.claude/skills/agent-style/references/RULES.md exists.
.claude/skills/style-review/SKILL.md points to the bundled agent-style references, not a required repository-level .agent-style/ directory.

If the target project still uses .agent-style/ directly, migrate by copying this entire skill folder and updating style-review source paths.

CLI Check

For deterministic audits, check:

agent-style --version

If missing, report:

agent-style deterministic audit unavailable: `agent-style` CLI is not on PATH. Bundled rules remain available for semantic review through `.claude/skills/agent-style/references/`.

Do not install dependencies unless the user asks.

Audit Routing

For file review, use style-review. This skill supplies the portable rule pack; style-review supplies the review workflow, audit command, polish invariants, and completion evidence.

Use this skill directly only for:

Checking whether Agent-Style travels with SDD apply/sync.
Reading the pinned rules or upstream metadata.
Migrating an older .agent-style/-based repo into .claude/skills.

Files

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.

Changes

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 tranhieutt/software_development_department (72 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 612 once invoked, about $0.0003 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.
