What it does

Loom is an agent skill from hashgraph-online/awesome-codex-plugins. Velith router. Detects book project state and runs the next phase of the 6-phase pipeline (onboarding → ideation → outlining → drafting → editing → publishing) to the human-quality bar. Trigger: /loom, /velith, or any book-writing request.

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `quality-bar.md`).

It sits in Agent Workflows, covering Brainstorming. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 78497e5. 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

    Shell commands in SKILL.md call:

    • node

    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

Loom loads about 2.4k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 975 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

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.

Velith — Books to the Human-Quality Bar

Velith produces books a cold reader cannot distinguish from a competent human author's work. Six phases, twelve agents, one standard: quality-bar.md in this directory. Read it once per session before doing any writing or editing work.

${CLAUDE_PLUGIN_ROOT} is this plugin's install directory. On hosts that do not substitute it, use the directory that contains velith.mjs.

Operating principles (supersede earlier Velith conventions)

  1. Full-manuscript context. Every writing and editing agent reads the entire manuscript so far, not summaries. Frontier models carry 1M tokens; a novel is under 200K. Voice drift and contradictions come from partial context. bible.md is an index and ledger, not a substitute for reading.
  2. Sequential drafting for narrative work. Fiction, screenplay, game narrative, memoir, narrative nonfiction, and poetry sequences draft strictly in order: chapter N is written only after chapter N-1 exists and its bible ledger is updated. Parallel drafting is allowed only for technical, reference, and academic books, only for chapters the outline DAG proves independent, and never more than 3 at once.
  3. Voice lock before volume. No book proceeds past its sample chapter until the author approves the voice. Drafting twenty chapters in a voice the author rejects wastes everything.
  4. Draft, critique, revise. No chapter is saved after a single pass. The writer cold-reads its own draft against the rubric, writes a critique with quoted lines, and revises. Editing stages rewrite the manuscript in place; they do not only file reports.
  5. Grounded claims. Nonfiction, technical, and academic manuscripts pass fact-check before line editing. A number, quote, or study that cannot be traced to sources/ or a verified URL is removed, not softened.
  6. Reader gate. Phase 4 ends with a cold read by simulated target readers. Publishing requires a PASS verdict or an explicit author override.
  7. One look per book. Images follow art-bible.md the way prose follows STYLE.md. Prompts are compiled from it, diagrams and drawings are code-rendered, every image passes vision QA, and a look lock precedes volume. See book-visuals.
  8. Author checkpoints. The pipeline stops for the author at six points: concept selection, outline approval, voice lock, look lock (if the book has images), developmental restructures, and readiness verdict. Everything else runs without asking.

Phase router

Run node ${CLAUDE_PLUGIN_ROOT}/velith.mjs scan <project-dir> to get project state, then route:

StateRoute
No PRD.mdPhase 0 /book-init
PRD.md but no ideation.md and no outline.mdPhase 1 /book-ideation
ideation.md but no outline.md (or outline lacks ## Approval)Phase 2 /book-outline
outline.md + bible.md, no draftsPhase 3 /book-draft (starts with voice lock)
Drafts exist, STYLE.md lacks ## Voice LockPhase 3 voice lock step, then continue drafting
Drafts incompletePhase 3 /book-draft (resume)
All chapters drafted, no edits/readiness-report.md with verdict: PASSPhase 4 /book-edit
Readiness PASS, no publish/book.epubPhase 5 /book-publish
Everything presentReport status; offer /book-illustrate, re-edit, or new project

With an explicit argument (/loom draft), run that phase regardless of detection, but still enforce the gates: drafting refuses to run without an approved outline; publishing refuses without readiness PASS unless --force.

Status and tooling

  • node ${CLAUDE_PLUGIN_ROOT}/velith.mjs scan <dir> [--ui] — project state, dashboard data
  • node ${CLAUDE_PLUGIN_ROOT}/velith.mjs metrics <file|dir> — sentence/paragraph statistics, repeated phrases, AI-tell counts (JSON)
  • node ${CLAUDE_PLUGIN_ROOT}/velith.mjs snapshot <dir> <label> — copy drafts/ to .velith/snapshots/ before a rewriting stage
  • node ${CLAUDE_PLUGIN_ROOT}/velith.mjs images compile|check|render <dir> [id] — model-agnostic image prompts from the art bible, asset validation, figure rendering
  • node ${CLAUDE_PLUGIN_ROOT}/velith.mjs agents <id> <running|complete|error> [task] — agent status for the dashboard

Every skill ends with scan so the dashboard stays current.

Integrations (optional)

  • alcove — search the author's document vault as source material during /book-init and drafting.
  • humanize-korean — if installed, style-doctor may run it as a final Korean polish after its own pass.
  • Image generation MCPs — cover-designer and illustrator produce prompts; if an image tool is available they can execute them.

When should I use Loom?

Loom fits situations like: tasks that involve Brainstorming.

How do I install Loom in Claude Code?

Run `npx skills add hashgraph-online/awesome-codex-plugins --skill loom -a claude-code`. Or copy the skill folder (plugins/epicsagas/Velith/skills/loom in hashgraph-online/awesome-codex-plugins) into .claude/skills/loom in your project. Claude Code loads it when a task matches its description.

How do I install Loom in Codex?

Run `npx skills add hashgraph-online/awesome-codex-plugins --skill loom -a codex`. Or copy the skill folder (plugins/epicsagas/Velith/skills/loom in hashgraph-online/awesome-codex-plugins) into .agents/skills/loom in your project. Codex loads it when a task matches its description.

Can I use Loom in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hashgraph-online/awesome-codex-plugins --skill loom -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/loom, .gemini/skills/loom, .github/skills/loom and .opencode/skills/loom in your project.

What does Loom need to run?

Going by SKILL.md and its folder, Loom needs the command-line tools its instructions call (node).

Does Loom access the network?

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.

Is Loom safe to install?

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.

What licence does Loom use?

Loom is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Loom use?

About 2.4k tokens (SKILL.md is roughly 9.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Loom?
