open-wot: Skill for Claude Code

.agents/skills/openspec-update-change/SKILL.md

openspec-update-change is a skill for Claude Code from wot-ui/open-wot. It costs 55 tokens per session (1,562 once invoked), scanned A, a copy of openspec-update-change, MIT.

A planning tool for revising an existing OpenSpec change. OpenSpec is a system that records software changes as linked planning documents, without changing the code itself.

In plain words
What is it for?
Use it to revise a change plan, add new decisions, or reconcile its documents after edits.
Why use it?
It keeps those planning documents consistent when decisions change, so the plan does not contradict itself.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is wot-ui/open-wot's own configuration. It tells Claude Code how to work on open-wot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything open-wot configures →

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

openspec-update-change 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 9d 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Revise a change's existing planning artifacts and keep them coherent. Never edit code.

Store selection: If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run openspec store list --json to discover registered store ids, then pass --store <id> on the commands that read or write specs and changes (new change, status, instructions, list, show, validate, archive, doctor, context, schemas, view). Once selected, treat --store <id> as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run openspec status --change "<name>" --json --store "<id>", not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local openspec/ root.

Input: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.

/openspec-continue-change is an optional workflow and may not be installed. Before suggesting it anywhere below, verify that it is available. If it is unavailable, openspec status --change "<name>" --json shows the next artifact and openspec instructions "<artifact-id>" --change "<name>" --json explains how to create it.

Steps

  1. Select the change

    If a name is provided, use it. Otherwise:

    • Infer from conversation context if the user mentioned a change
    • Auto-select if only one active change exists
    • If ambiguous, run openspec list --json to get available changes sorted by most recently modified, and ask the user to select one

    When prompting, present the top 3-4 most recently modified changes as options, showing:

    • Change name
    • Schema (from schema field if present, otherwise "spec-driven")
    • Status (e.g., "0/5 tasks", "complete", "no tasks")
    • How recently it was modified (from lastModified field)

    Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to update.

    Always announce: "Using change: " and how to override (e.g., /openspec-update-change <other>).

  2. Get the change's artifacts

    openspec status --change "<name>" --json
    

    Parse the JSON to understand current state. The response includes:

    • schemaName: The workflow schema being used (e.g., "spec-driven")
    • artifacts: Array of artifacts with their status ("done", "skipped", "ready", "blocked")
    • isPlanningComplete: Boolean indicating if all planning artifacts are complete. Older CLI versions expose the same value as isComplete.
    • planningHome, changeRoot, artifactPaths, and actionContext: path and scope context. Use these instead of assuming repo-local paths.

    The artifact ids and paths come from the active schema - do NOT assume them, and do NOT branch on hardcoded artifact names. Custom schemas must work unchanged.

    The files to edit are artifactPaths.<id>.existingOutputPaths - the concrete files that exist on disk, already glob-expanded for glob artifacts (e.g. specs/**/*.md). Do NOT write to resolvedOutputPath: for a glob artifact it is still the glob pattern, not a real file.

  3. Understand the request

    • If the user asked for a specific revision ("the design now uses X"), that is the starting edit.
    • If they only said "update" / "make this coherent", treat it as a coherence review: read the existing artifacts and check them against each other for contradictions, gaps, and duplication.
  4. Read and reconcile

    • Read the artifact(s) the request touches and the change's other existing artifacts.
    • Apply the requested edit. Then check every other existing artifact against it - in ANY direction: an edit to a later artifact may require revising an earlier one, not only the other way around. Build order is a useful reading order, not a constraint on which artifacts may be revised.
    • Note everything that is now inconsistent, missing, or contradictory.
    • Revise only files that already exist (existingOutputPaths). Do NOT create artifacts that don't exist yet, and do NOT invent new files under a glob artifact - note them and point the user to /openspec-continue-change to create them.
    • If the change is already coherent, say so and make no edits.

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.
