review-pubsub-subscriptions

review-pubsub-subscriptions is a skill for Claude Code from diagrid-labs/dapr-skills. It costs 69 tokens per session (1,265 once invoked), scanned A, original, MIT.

A read-only review procedure for Dapr pub/sub subscriptions and message handlers in .NET and Python. It checks how applications receive messages, including subscription files, code-based subscriptions, streaming subscriptions, and the responses handlers send.

In plain words
What is it for?
It reviews CloudEvent handling, success, retry and drop responses, duplicate handling, dead-letter processing, routing rules, duplicate subscriptions, and routes that point to no endpoint.
Why use it?
It finds message-delivery problems before they cause lost, repeated, or incorrectly routed work. It does not modify source files.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

review-pubsub-subscriptions 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 4d 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.

Review Dapr Pub/sub — Subscriptions and Handlers

Overview

Reviews how an app receives Dapr pub/sub messages: declarative kind: Subscription files, programmatic subscriptions ([Topic], .WithTopic, DaprApp.subscribe) and streaming subscriptions (Dapr.Messaging, subscribe_with_handler). Checks CloudEvent handling, SUCCESS / RETRY / DROP responses, idempotency, dead-letter handling, match expressions, the same topic subscribed through two types, and declarative routes that have no endpoint. Read-only: this skill never modifies source files. Publishing code and component configuration are out of scope and are covered by review-pubsub-publishing and review-pubsub-components.

Execution Order

You MUST follow these phases in strict order. Do not load files outside the agreed scope, and do not write or edit any files.

  1. Resolve scope — Read ../dapr-shared/review-scope-prompt.md and follow it to set scope_root.
  2. Detect target — Read ../dapr-shared/review-detect-target-pubsub.md and follow it to produce language, subscriptions, handler_files, subscription_files, plus publisher_files and run_files as context. If subscriptions is empty, emit the "Nothing to review" report defined in review-report-format.md with the reason no pub/sub subscription files found in <scope_root> (no rule id, not counted in Found:) and stop.
  3. Load checklist — Based on language, read exactly one of:
  4. Apply rules per type — Group subscriptions by type (declarative, programmatic, streaming). For each group, apply only the rules whose Types column includes that type (HTTP means declarative or programmatic) to the entries and their handlers. Then run the cross-type pass over all subscriptions together:
    • DPS-SUB-014 — the same pubsub and topic subscribed through two or more types in one app. Resolve scopes to app ids first.
    • DPS-SUB-015 — a declarative routes.default or rules[].path with no matching POST endpoint in the app it is scoped to.
  5. Report — Format every finding using the canonical template from ../dapr-shared/review-report-format.md. Group by severity, then rule id, then file path. Put low-confidence findings (indirect side effects, handler files outside the scope) under ## Please verify.
  6. Show final message — Your last output is the report. Do not append a summary or next-action prompt other than the ## Next steps block defined by the report format. Clarifying questions are always allowed during the review (see the report format); once answered, the report is still your last output.
