What it does

Write Chapter is an agent skill from forsonny/Claude-Code-Novel-Writer. Draft the next chapter or a specified chapter from the accepted outline while preserving manuscript continuity, character knowledge, and established voice.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Use Claude Code CLI to write full novels.

Example prompts

  • “/write-chapter”

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  1. Resolve the repository root and run ./sync-state.sh --quiet.
  2. Determine the target chapter from the invocation, outline, and tracking state.
  3. Refuse to overwrite substantial existing prose unless the request clearly asks for revision.
  4. Read the relevant outline beat, previous chapter, directly relevant earlier chapters, character state, world state, and continuity notes.
  5. Read .agents/roles/chapter-writer.md.
  6. If the harness exposes a named chapter-writer specialist, delegate the complete bounded draft to it. Otherwise perform that role directly.
  7. Write the chapter to manuscript/chapters/chapter-N.md, preserving repository formatting conventions.
  8. Run automation/quality-check.sh manuscript/chapters/chapter-N.md for mechanical signals unless a lifecycle hook already did so.
  9. Run ./sync-state.sh.
  10. Report the file, approximate word count, story-state changes, continuity facts, and any downstream concern.

What it can do on your machine

Read from SKILL.md and the folder at commit 017cd8b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Write Chapter loads about 339 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 151 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~339

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.

Safety

Auto-check passed

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 151 words (~339 tokens).
