template-update

Codifies an insight from another agent session into the opencode-project-template. Handles placement, versioning, and changelog in a single pass.

When to use

Invoke with /template-update when you have a conversation excerpt, lesson learned, or architectural pattern from another project that should be baked into the template so all future consuming projects inherit it.

Inputs

The user must provide (inline or as a file path):

• Conversation excerpt or insight description — the raw context from the other session. Can be a pasted conversation, a summary, or a direct statement of what the rule/protocol should be.
• Target (optional) — which template file to update. If omitted, the skill will determine the best fit.

Steps

1. Read current state

cat .template-version

Read the files that are candidates for the update:

• template/CLAUDE.md — orchestration rules, delegation protocols, session behaviour
• template/protocols.md — secrets, permission gates, code style
• global-config/claudecode/CLAUDE.md — machine-scoped global rules (not per-project)

Determine which file owns the kind of rule being added:

• Agent behaviour / delegation patterns → template/CLAUDE.md
• Code style / secrets / permission gates → template/protocols.md
• Machine-scoped rules that apply to all projects globally → global-config/claudecode/CLAUDE.md

2. Extract and phrase the pattern

From the provided context, extract:

• The trigger condition (when does this pattern apply?)
• The steps or rules (what should the agent do?)
• The rationale (why is this better than the default behaviour?)

Phrase it as a second-person instruction to the orchestrator agent ("When X, do Y because Z"), matching the voice and style of the target file.

3. Identify insertion point

Read the target file. Find the section that best fits the new content:

• New delegation protocol → under ## Delegation rules
• New session behaviour → under ## Session start
• New permission gate → under ## Permission gates
• New agent roster entry → under ## Subagent roster

If no existing section fits, create a new ### subsection under the most relevant ## section.

4. Apply the change

Edit the target file to insert the new content. Preserve:

• Existing heading hierarchy
• Markdown list and code block style
• The concise, imperative tone of the surrounding text

5. Update CHANGELOG.md

Add a new entry at the top of CHANGELOG.md (above the current latest version):

## [X.Y.Z] — YYYY-MM-DD

### Added / Changed
- `<target-file>` — one-sentence summary of what was added and why.

The new version must be a minor bump (e.g. 1.10.0 → 1.11.0) because adding a protocol is a backward-compatible feature addition. Only use a patch bump for pure wording fixes.

6. Bump .template-version

echo "X.Y.Z" > .template-version

7. Confirm

Print a summary:

• What was added and where
• New version
• One-line CHANGELOG entry

Expected output

• Target template file updated with the new protocol or rule
• CHANGELOG.md has a new entry at the top
• .template-version reflects the new version
• A brief summary printed to the user confirming what changed
