edit-for-readability

edit-for-readability is a skill for Claude Code, Codex from testdouble/han. It costs 186 tokens per session (2,255 once invoked), scanned A, original, MIT.

A prose-editing workflow that rewrites an existing draft or file for easier reading. It puts the main point first and improves headings and paragraph structure while preserving the facts.

In plain words
What is it for?
Use it to revise text pasted into a prompt, stored in a file, or already produced during the conversation.
Why use it?
It helps when technical or business writing is accurate but difficult to scan or understand. The rewrite makes the existing content clearer without adding new claims.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

Security

Grade A, and why

edit-for-readability 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 — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Context

  • personal config directory: !bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh" 2>/dev/null || echo "$HOME/.claude"
  • project .han/config.md: !cat .han/config.md 2>/dev/null || echo ""

As your first action, use the Read tool on .han/config.md inside the personal config directory path above. 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.

Edit for Readability

Take a target the user already has and rewrite its prose against the shared readability standard, preserving every fact. The judgment-heavy rewrite belongs to the han-communication:readability-editor agent; this skill's job is to resolve what the target is, dispatch the editor over it, and deliver the result.

Operating principles

  • This is the standalone readability pass. The readability standard applies at generation time, so synthesis skills (research, project-documentation, investigate, code-review, and the rest) already bake it into their own output. This skill exists for the gap the standard names explicitly: a file or draft that was written or hand-edited outside one of those skills, and so was never checked against the standard. Reach for it on an existing target, not as a step inside another skill.
  • Fidelity outranks readability on every conflict the user did not create. Every claim, quantity, named entity, and stated condition or qualifier in the target survives the rewrite with its precision intact. The editor enforces this and returns a fact-preservation ledger; the skill's job is to pass the whole target through and surface that ledger, never to let a fact be dropped for the sake of a smoother sentence. A shape the user asked for is the one thing that moves this, and never for a fact whose loss would change what the reader does next.
  • Prose only. The editor rewrites prose regions and leaves code fences, diagram bodies, rendered markup, and citation identifiers (A1, [F5], and the like) byte-for-byte unchanged. Do not ask it to touch anything else.
  • The editor holds the standard. Do not restate the rubric criteria here or inline the rule text into the dispatch. The editor reads its own co-located canonical rule and applies the current standard, so this skill never drifts from readability-rule.md.

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.
