Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00166 | $0.01024 |
| Opus 5 | $0.00083 | $0.00512 |
| Sonnet 5 | $0.00033 | $0.00205 |
| Haiku 4.5 | $0.00017 | $0.00102 |
Grade A, and why
couchbase-xdcr 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 12d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Couchbase XDCR
A skill for designing and operating Cross-Datacenter Replication between Couchbase clusters.
Distinct from:
couchbase-app-integration— application code patterns for XDCR-aware reads and writescouchbase-migration-execution— one-time migration, not ongoing replication
If the conversation is "I need data in multiple regions" or "how do I keep two clusters in sync," this is the right skill.
When this skill applies
- "How do I replicate between two clusters?"
- "Active-active vs active-passive — which should I use?"
- "How does conflict resolution work in XDCR?"
- "How do I filter which documents get replicated?"
- "How do I monitor XDCR lag?"
- "XDCR replication is behind — how do I diagnose it?"
- "What's the XDCR conflict log in 8.x?"
Pick the right reference
| Question | Read |
|---|---|
| "Active-active vs active-passive — topology decision" | references/topology.md |
| "How do I create references and replications, filter docs, tune performance?" | references/configuration.md |
| "Conflict resolution — LWW, custom, 8.x conflict logging" | references/conflict-resolution.md |
| "Replication is lagging / errors / mismatched counts" | references/troubleshooting.md |
Three core principles
Principle 1 — Active-active means accepting eventual consistency and conflict potential. In active-active (bidirectional) XDCR, both clusters accept writes independently. When the same document is written on both sides before replication catches up, a conflict occurs. Couchbase resolves it automatically (last-write-wins by default in 7.x; custom resolution in 8.x), but the losing write is silently dropped. If you can't accept silent drops for any write, active-active is not the right topology.
Principle 2 — XDCR is bucket-to-bucket, not cluster-to-cluster. A replication runs between a specific source bucket and a specific destination bucket. If you have 5 buckets, you need 5 replication configurations. Plan this explicitly — it's common to accidentally replicate only some buckets and have inconsistent DR coverage.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

couchbase-xdcr is a skill published in the GitHub repository celticht32/Couchbase-Skills-for-Claude.ai (4 stars, last pushed 2mo ago), licensed MIT. It adds 166 tokens to every session and 1,024 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
