Deferred Capture

Deferred Capture Contract

When To Use

• Building a new plugin deferred-capture wrapper
• Validating an existing wrapper against the contract
• Adding new source labels or template fields

When NOT To Use

• Capturing a deferred item at runtime (use the plugin wrapper directly, e.g. scripts/deferred_capture.py)
• Creating GitHub issues manually

Specification that all plugin deferred-capture wrappers implement. Not a runtime dependency, just a convention.

CLI Interface

Required arguments:

• --title (str): Concise description. Becomes issue title after [Deferred] prefix
• --source (str): Origin skill. One of: war-room, brainstorm, scope-guard, feature-review, review, regression, egregore
• --context (str): Why raised and why deferred

Optional arguments:

• --labels (str): Comma-separated additional labels beyond deferred and source
• --session-id (str): Session ID. Canonical source: session_id from the hook payload stdin (jq -r '.session_id'), fallback: UTC timestamp YYYYMMDD-HHMMSS
• --artifact-path (str): Absolute path or $HOME-based path to source artifact
• --captured-by (str): explicit (default) or safety-net
• --dry-run (flag): Print JSON output without creating issue

Issue Template

Title: [Deferred] <title>

Labels: deferred and <source>

Body:

## Deferred Item

**Source:** <source> (session <session-id>)
**Captured:** <YYYY-MM-DD>
**Branch:** <current git branch>
**Captured by:** <explicit|safety-net>

### Context

<context argument verbatim>

### Original Artifact

<artifact-path if provided, otherwise "N/A">

### Next Steps

- [ ] Evaluate feasibility in a future cycle
- [ ] Link to related work if applicable

Label Taxonomy

Duplicate Detection

Search: gh issue list --search "<title> in:title" --state open --json number,title

Compare: exact title match after stripping [Deferred] prefix and normalizing to lowercase.

Only open issues are checked. Re-filing a closed deferred item is intentional.

Output (JSON to stdout)

Created: {"status": "created", "issue_url": "...", "number": 42} Duplicate: {"status": "duplicate", "existing_url": "...", "number": 17} Error: {"status": "error", "message": "..."}

Compliance Test

Any wrapper can verify conformance with:

python3 scripts/deferred_capture.py \
  --title "Test: compliance check" \
  --source test \
  --context "Automated compliance verification" \
  --dry-run

Must output valid JSON with a status field.

Exit Criteria

• Compliance test passes: deferred_capture.py --dry-run outputs valid JSON with a status field (created, duplicate, or error) for any conformant wrapper
• Created issues have title prefixed [Deferred], carry both the deferred label and the source label, and body matches the required template (Source, Captured, Branch, Captured by, Context, Original Artifact, Next Steps)
• Duplicate detection runs before creation: gh issue list --search "<title> in:title" called and exact match (after stripping prefix and lowercasing) suppresses the new issue
• JSON written to stdout on every invocation; {"status": "created", "issue_url": "...", "number": N} on success, {"status": "duplicate", ...} on duplicate, {"status": "error", "message": "..."} on failure
