Update Agent-Context
Update shared Agent-Context files to the latest version without touching project-owned content.
Examples
# Update to latest version
/agent-context-update
# Update to a specific version
/agent-context-update v0.3.0
Prerequisites Check
Before starting, verify Agent-Context is installed:
cat .agent-context/.agent-context-version 2>/dev/null
- If the file does not exist: STOP. Tell the user Agent-Context is not initialized and suggest using the
initskill instead. - If the file exists: note the current version and proceed.
Update
Resolve the target release tag first, then fetch the setup prompt pinned to that tag and follow its instructions. Fetching a specific release tag (never the mutable main branch) is deliberate: the tag is pinned for the whole run, so the fetched prompt is fixed between resolution and execution, and it changes only when a new release is published — unlike main, which every push mutates. (Full tamper-resistance additionally requires tag/release protection on the source repo.)
# Resolve target version: explicit $ARGUMENTS, else latest release (never mutable `main`)
TAG="${ARGUMENTS:-$(gh api repos/lx-wnk/Agent-Context/releases/latest --jq .tag_name)}"
curl -fsSL "https://raw.githubusercontent.com/lx-wnk/Agent-Context/${TAG}/.prompts/setup-prompt.md"
The setup prompt auto-detects UPDATE mode (because .agent-context-version exists). Follow the fetched instructions, subject to the consent gates in Trust Boundary & Consent below. The setup prompt handles:
- Version check — fetch latest release, compare with current version
- Shared file refresh — overwrite only shared files (
agent-startup.md,layer0-agent-workflow.md,base-principles.md,plugins.json) - New templates — create any new template files introduced in the new version (without overwriting existing ones)
- Agent sync — update shared agents where they already exist
- Plugin sync — merge new plugins into
.claude/settings.json - Compatibility check — scan for deprecated patterns and suggest fixes
If $ARGUMENTS contains a version tag, use that version instead of latest.
Trust Boundary & Consent
This skill fetches a remote setup prompt (pinned to a release tag, see above) and follows it. That prompt performs trust-expanding operations: it can update transitive agents, merge plugins, and modify .claude/settings.json. Treat these as privileged, even though this is an update into an already-initialized project.
Before any step that updates agents (4), merges plugins (5), or writes to .claude/settings.json, stop and get explicit user confirmation — since this merges into an existing configuration, list exactly what will be ADDED or CHANGED against the current state, then wait for a yes. Never install transitive agents or merge plugins silently. If the user declines a step, skip it and continue with the rest of the update.
What is NEVER touched
AGENTS.md,layer1-bootstrap.md,layer2-project-core.md,layer3-guidebook.md- All files in
memory/andskills/ decisions.json.claude/settings.json(only additive merges)
After Update
Report:
- Previous version → new version
- Files updated
- Any new templates created
- Compatibility warnings (if any)
