What it does

Queue is an agent skill from iii-hq/workers. Durable topic queues for iii: subscribe functions to topics, publish work asynchronously, retry failed deliveries with backoff, and inspect/redrive dead-lettered messages.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit d3c6b85. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml and typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Queue loads about 1.2k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 488 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~44
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: queue
description: Durable topic queues for iii: subscribe functions to topics, publish work asynchronously, retry failed deliveries with backoff, and inspect/redrive dead-lettered messages.
tags: queue, durable, retries, dlq, pubsub

queue

The queue worker provides durable topic delivery for iii. Register a consumer with a durable:subscriber trigger, publish with iii::durable::publish, and the worker persists messages, retries failed deliveries, moves exhausted jobs to DLQ, and exposes redrive/discard inspection functions.

Install it with iii trigger compose::add worker=queue. The legacy built-in queue service must be removed from the engine config before this worker starts because both would own the same durable:subscriber trigger type.

When to Use

A topic event must be processed reliably by a subscribed function.
A failed consumer should retry automatically before the message lands in DLQ.
You need to inspect, redrive, or discard dead-lettered messages.
Local or single-instance durable queues are enough, using in-memory storage for development or file-backed storage for restart survival.

Boundaries

Not fire-and-forget broadcast. Use pubsub when missed events are acceptable.
Three transports ship today: builtin (in-process, full DLQ/retry/fifo), redis (pub/sub only, no DLQ), and rabbitmq (full: retry/DLQ/priority/fifo). The bridge adapter is not ported — it was engine-internal and is superseded by the engine's QueueEnqueuer cut (MOT-3829).
Engine TriggerAction.Enqueue / named function queues require the separate QueueEnqueuer engine cut. Until that lands, use iii::durable::publish and durable:subscriber triggers for this standalone worker.
File-backed mode survives worker restarts. In-memory mode loses pending jobs on restart or transport hot-swap. An unreachable redis/rabbitmq target at boot fails the boot (no fallback to builtin).
fifo mode is strictly serial — there is no grouped-fifo partitioning by group_id like the engine's GroupedFifoWorker.
This worker carries work items, not key/value or stream state. Use state or stream for those.

Functions

iii::durable::publish: publish a JSON payload to a queue/topic. Input accepts { "queue": "...", "data": ... } and also accepts topic as an alias.
iii::queue::redrive: move all DLQ messages for a queue back to the main queue. Input accepts queue or topic.
iii::queue::redrive_message: move one DLQ message back by message_id.
iii::queue::discard_message: purge one DLQ message by message_id.
engine::queue::list_topics: list known queue topics.
engine::queue::topic_stats: return depth, consumer_count, and dlq_depth for one topic.
engine::queue::dlq_topics: list DLQ topics with message counts.
engine::queue::dlq_messages: browse DLQ messages with offset and limit.

Reactive Triggers

Bind a durable:subscriber trigger when a function should consume every message published to a queue/topic with retries and DLQ handling.

typescript

iii.registerTrigger({
  type: 'durable:subscriber',
  function_id: 'orders::process',
  config: {
    queue: 'orders.created',
    max_retries: 3,
    backoff_ms: 1000,
  },
})

Trigger config:

queue (required): topic/queue name to consume. topic is accepted as a compatibility alias.
max_retries (default 3): failed attempts before moving to DLQ.
backoff_ms (default 1000): base retry delay. Retries use the same exponential curve as the builtin queue: backoff_ms * 2^(attempts - 1).
condition_function_id (optional): called before the handler; only explicit false skips the handler.

Configuration

Use the configuration worker entry named queue. The default is in-memory:

yaml

adapter:
  name: builtin

For restart survival, use file-backed storage:

yaml

adapter:
  name: builtin
  config:
    store_method: file_based
    file_path: data/queue
    save_interval_ms: 5000

For pub/sub-only delivery against a shared Redis (no DLQ, no durability):

yaml

adapter:
  name: redis
  config:
    redis_url: redis://localhost:6379

For full retry/DLQ/priority/fifo delivery against RabbitMQ:

yaml

adapter:
  name: rabbitmq
  config:
    amqp_url: amqp://localhost:5672
    max_attempts: 3
    prefetch_count: 10
    queue_mode: standard
    priority_field: priority

Changing the adapter config hot-swaps the transport and restarts every consumer — the new adapter is built first, so a bad config leaves the previous one serving. File-backed jobs survive by construction; in-memory jobs are lost, matching the builtin adapter's in-process durability profile.

When should I use Queue?

Queue fits situations like: backend & APIs work in your project.

How do I install Queue in Claude Code?

Run `npx skills add iii-hq/workers --skill queue -a claude-code`. Or copy the skill folder (queue/skills in iii-hq/workers) into .claude/skills/queue in your project. Claude Code loads it when a task matches its description.

How do I install Queue in Codex?

Run `npx skills add iii-hq/workers --skill queue -a codex`. Or copy the skill folder (queue/skills in iii-hq/workers) into .agents/skills/queue in your project. Codex loads it when a task matches its description.

Can I use Queue in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add iii-hq/workers --skill queue -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/queue, .gemini/skills/queue, .github/skills/queue and .opencode/skills/queue in your project.

What does Queue need to run?

SKILL.md names no scripts, command-line tools or credentials: Queue is instructions for the agent only.

Does Queue access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Queue safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Queue use?

Queue is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Queue use?

About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Queue?
