saga

saga is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 15 tokens per session (421 once invoked), scanned A, original, MIT.

A guide to the Saga pattern, a way to coordinate a transaction spread across several microservices, such as booking a flight, booking a hotel, and charging a card.

In plain words
What is it for?
Use it to design distributed transactions, choose between a central coordinator and event-based coordination, handle failures, and maintain eventual consistency between services.
Why use it?
A single database transaction usually cannot safely cover separate services or long-running work. Saga steps use local changes and compensation actions, such as cancelling earlier bookings when a later step fails.

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

saga 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 9d 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.

What it actually says

Saga Pattern

The Saga pattern manages data consistency across microservices in distributed transaction scenarios. A Saga is a sequence of local transactions. Each local transaction updates the database and publishes a message or event to trigger the next local transaction in the saga.

When to Use

  • Distributed Transactions: e.g., "Book Flight" + "Book Hotel" + "Charge Card".
  • Long-running processes where you can't hold a DB lock.
  • Ensuring eventual consistency across Services A, B, and C.

Core Concepts

Compensating Transactions

If a step fails (e.g., Card Declined), the Saga must execute compensating transactions to undo the changes made by the preceding steps (e.g., "Cancel Hotel", "Cancel Flight").

Choreography

Each service listens to events and decides what to do.

  • Order Service -> OrderCreated
  • Inventory Service -> listends to OrderCreated -> does work -> InventoryReserved

Orchestration

A central coordinator (Orchestrator) tells each service what to do.

  • Orchestrator -> Call Order Service
  • Orchestrator -> Call Inventory Service
  • Orchestrator -> Handle failure -> Call Compensation.

Best Practices

Do:

  • Prefer Orchestration for complex sagas (easier to visualize and trace).
  • Ensure all steps are Idempotent.
  • Design for failure (Everything that can fail, will fail).

Don't:

  • Don't rely on synchronous HTTP calls for Sagas (What if the network drops in the middle?). Use Message Queues or Persistent Orchestrators (Temporal).

Tools

  • Temporal.io: Workflow engine for code-based orchestration.
  • MassTransit (C#): Built-in Saga state machines.

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.

saga is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 15 tokens to every session and 421 once invoked, about $0.0001 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 2026-08-30.
