Readability Guidance is an agent skill from testdouble/han. Surfaces Han's shared Human-Readable Output Standard — the readability rule and the writing-voice profile — into the calling skill's own context, so the caller drafts in voice and runs its self-check against the current standard sourced from one canonical copy. Use when a prose-producing skill needs the shared readability standard available in context before it drafts. Governs the shape of a written deliverable, where explanation-guidance governs what a run says to a person in a turn. Runs in the caller's context…
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Plain language and style rules, Verification before completion and Brand voice and tone. The repository describes itself as: Han: AI skills and agents for "Solo" product engineers and small teams. The licence is MIT.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit abba73a. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash(bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh")From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
bashFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Readability Guidance loads about 1.6k tokens when it runs. Until then it costs about 233 tokens; SKILL.md has 814 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

A read
that returns no file is no personal configuration: continue silently. When that file or the project .han/config.md
probe supplies content, apply it per config-rule.md, which governs precedence
between the two files, relative-path resolution, and what to do with a file that reads but cannot be used.
You have invoked readability-guidance to source the shared readability standard before you draft prose. This skill
surfaces the standard into your own context and hands control back. It is a means to writing your deliverable, not the
deliverable itself: apply what it surfaces while you draft and self-check, then RETURN to the workflow that called you
and finish it.
This skill is inline — it runs in your context, not an isolated one, so the standard it surfaces stays available to you after it returns. Do not treat anything here as a stopping point or a final answer.
A structured specification, plan, phased build, work-item list, coding standard, or test plan is reader-facing whenever a human reads it end to end — to approve it, follow it, or build from it — even when downstream skills also consume it. Only an artifact consumed purely as a pipeline input, with no human reading it end to end, falls outside the standard. If a human reads your deliverable end to end, apply the standard to it.
First resolve which writing-voice profile this run uses:
.han/config.md probe supplied a writing-voice value, resolve it and check that the file exists. A
relative value resolves against the folder holding the file that declared it: the working directory for the project
file, and the personal config directory the probe reported for the personal file. A full path is used as it stands,
and a leading ~ expands to the home directory. When both files supply a value, the project file's wins.writing-voice value, the built-in profile at
${CLAUDE_PLUGIN_ROOT}/references/writing-voice.md applies.Then read the reference files, in this order, so their full content enters your context:
${CLAUDE_PLUGIN_ROOT}/references/readability-rule.md — the Human-Readable Output Standard: the audience frame, the
output properties, the length guidance, the prose-only and fidelity rules, and the standardized self-check.${CLAUDE_PLUGIN_ROOT}/references/writing-voice.md, whose "Avoided words and phrases" and "AI slop to avoid"
sections are the authoritative vocabulary blocklist the rule points to. A configured profile stands in for the
built-in one wholesale: apply whatever voice and vocabulary guidance it carries. When the user chose to skip the
writing voice, read only the readability rule and apply it with no voice profile and no vocabulary blocklist.Do not paraphrase or summarize the files in place of reading them — the surfaced content is the point.
While you draft, write for a capable reader who did not do this work and lacks the author's context. If the calling skill names a specific reader (an engineer implementing a fix, a PR reviewer, a non-technical stakeholder), write for that reader instead and keep the technical specifics that reader needs. The frame governs how a fact is said, never whether a required fact appears.
The standard takes effect in stages, never as one stacked instruction block:
han-communication:readability-editor for the adversarial rewrite
after your full draft exists, as the standard reserves that pass for synthesis output. This skill does not run that
rewrite.The standard is now in your context. Proceed to the next step of the skill that invoked you and produce its deliverable.

Readability Guidance is an agent skill from testdouble/han. Surfaces Han's shared Human-Readable Output Standard — the readability rule and the writing-voice profile — into the calling skill's own context, so the caller drafts in voice and runs its self-check against the current standard sourced from one canonical copy.
Readability Guidance fits situations like: A prose-producing skill needs the shared readability standard available in context before it drafts; tasks that involve Plain language and style rules; tasks that involve Verification before completion.
Run `npx skills add testdouble/han --skill readability-guidance -a claude-code`. Or copy the skill folder (han-communication/skills/readability-guidance in testdouble/han) into .claude/skills/readability-guidance in your project. Claude Code loads it when a task matches its description.
Run `npx skills add testdouble/han --skill readability-guidance -a codex`. Or copy the skill folder (han-communication/skills/readability-guidance in testdouble/han) into .agents/skills/readability-guidance in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add testdouble/han --skill readability-guidance -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/readability-guidance, .gemini/skills/readability-guidance, .github/skills/readability-guidance and .opencode/skills/readability-guidance in your project.
Going by SKILL.md and its folder, Readability Guidance needs the command-line tools its instructions call (bash). Its frontmatter pre-approves these tools: Read, Bash(bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh").
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Readability Guidance is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
