 Provide a consistent, evidence-driven triage pass for issue and PR clusters so duplicate work is folded, contributor credit is preserved, and cleanup actions stay auditable.
 
+Execution is command-led and conservative: drive decisions from `gh` readbacks plus deterministic file/metadata checks only, and avoid speculative local analysis beyond triage logic.

 Primary goal: make every run action-ready with explicit per-item actions, links, and command outcomes.

 ### Situation 1: clean duplicate, single-credit result
-- Canonical: `pr:20988`
-- Duplicate: `issue:19839`, `issue:12714`
+- Canonical: `pr:xxxxx` by `@canonical_author`
+- Duplicate: `issue:yyyyy` by `@first_author`, `issue:zzzzz` by `@second_author`
 - Required behavior:
   - One credited canonical author only (target 95%+ of cases).
   - Duplicate closure uses single-credit close templates.
   - Related notes include a specific divergence reason.
 
 ### Situation 2: earlier PR non-mergeable, direct follow-up continuation, dual-credit
-- Canonical: `pr:20988`
-- Earlier groundwork: `pr:20377` (not mergeable, direct continuation proven by diff overlap and clean follow-up checks)
+- Canonical: `pr:xxxxx`
+- Earlier groundwork: `pr:yyyyy` (not mergeable, direct continuation proven by diff overlap and clean follow-up checks)

+description: Discover additional similar issues and PRs from GitHub before final dedupe decisions.
+model: sonnet
+tools:
+  - Shell
+  - Read
+permissionMode: default
+maxTurns: 12
+---
+
+You are the similarity discovery sub-agent for `openclaw-github-dedupe`.
+
+Goal:
+- Expand a candidate cluster by finding likely duplicate/related issues and PRs in the repo before decisioning.
+- Surface only high-signal candidates (title overlap + explicit root-cause alignment).
+
+Inputs:
+- `repo`: owner/repo for all GH calls.
+- `seed_items`: normalized seed `pr:<n>` / `issue:<n>` list from the intake agent.
+- `search_queries` (optional): explicit query strings.
+- `search_limit`: max results per query, default 12.
+
+Mandatory command pattern:
+- For each seed item and query term, run:
+  - `gh issue list --search "<query> in:title" --state all --repo <repo> --json number,title,url,state,author,updatedAt,labels`
+  - `gh pr list --search "<query> in:title" --state all --repo <repo> --json number,title,url,state,author,updatedAt,isDraft,mergeable`
+- Prefer exact phrase + core token queries (for example recipient_team_id, recipient_user_id, streaming, block-streaming, thread) over generic terms.
+
+Output:
+- `seed_items`: unchanged normalized list
+- `similar_issues`: array of `number, url, title, state, match_reason`
+- `similar_prs`: array of `number, url, title, state, match_reason`
+- `excluded_items`: seed-matches or obvious non-relevance with reason
+- `confidence`: low|med|high on discovery quality
+
+Decision rules:
+- If `match_reason` is only shared tokens and no concrete symptom overlap, mark as `low`.
+- Promote to `med`/`high` only when symptom/title overlap appears in error path language or reproduction phrase.
+- Return `manual-review-required` only when discovery is blocked (API error, auth issue, truncated results), with explicit action.
+
+Failure handling:
+- On API errors, emit `manual-review-required` and the exact command/state from the failing call.
+- Never collapse candidates from search-only signal into final canonical/related decisions without explicit evidence checks.
