A command that sends non-urgent tasks to a scheduler, which chooses a lower-carbon electricity period before a deadline.

Use it to defer coding or other agent tasks to a specified or inferred deadline. The task is sent to the ebb-ai scheduler for later execution.

It lets work happen later when the electricity supply is cleaner, instead of running it immediately. It turns everyday phrases such as “by tomorrow” or “overnight” into a scheduled task.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00164	$0.01907
Opus 5.5	$0.00066	$0.00763
Sonnet 5.5	$0.00033	$0.00381
Haiku 4.5	$0.00016	$0.00191

Security

Grade A, and why

defer 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 21d 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The user wants to defer the following task to a cleaner-grid window using the ebb-ai MCP server. This is the central UX of the ebb-ai Claude Code plugin — take a "do it later" request and route it to a real scheduler.

When to invoke automatically (without the user explicitly typing /ebb-ai:defer)

Any of these signals means the user has implicitly opted into deferral. Convert their wording to an ISO-8601 deadline and call schedule_task:

User phrase	Implied deadline
"by tomorrow"	tomorrow, end of working day (18:00)
"tonight" / "overnight"	tomorrow, 06:00 local
"by EOD"	today, 18:00 local
"this week"	Friday, 18:00 local
"next week"	next Friday, 18:00 local
"when you have a moment"	+24 h
"remind me to X"	+24 h, unless a time is named
"no rush" / "not urgent"	+48 h
"schedule this for X"	parse X explicitly
"queue this up"	+12 h

If the user does NOT signal "later" (e.g. "summarize this", "write a function", "what does X do"), do not auto-defer. Run inline.

If the user explicitly typed /ebb-ai:defer ..., follow the explicit args. The auto-invocation above is for the unprompted case only.

Arguments

$ARGUMENTS

Parse $ARGUMENTS into:

Prompt — everything before the first -- flag, or the whole argument string if no flags are present. Required. If empty, ask the user what task they want to defer.
--by <duration> — deadline. Accepts 2h, 30m, 24h, 3d, or an ISO-8601 timestamp. Default: 24h from now. Must resolve to the future.
--budget <grams> — optional hard cap on grams CO2-equivalent. If the scheduler can't find a window that meets it, the task fails fast with a CarbonBudgetExceededError.
--region <zone> — optional Electricity Maps zone code (e.g. US-CAL-CISO, GB, FR). Default: omit the field — the server resolves its own default (EBB_DEFAULT_REGION if configured, otherwise a guess from the host machine's timezone, falling back to GB). The region line in the tool response tells you what it picked; relay that to the user.
--model <name> — optional vendor model id (e.g. claude-sonnet-5). Without it the server uses the chosen provider's default: claude-sonnet-5 for anthropic (overridable with EBB_DEFAULT_MODEL), gpt-6-sol for openai. The model line in the tool response shows what it picked.
--output <abs-path> — optional absolute file path. When the task completes, ebb-ai writes { taskId, result, receipt } as JSON to this path. Useful if the user wants the result to land in an inbox folder (so tail -f or a file-watcher surfaces it) rather than polling /ebb-ai:check by hand. Recommend ~/.ebb-ai/inbox/<task_id>.json when the user is unsure where to put it.
--provider <anthropic|openai> — optional. Default anthropic.

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.

defer is a command published in the GitHub repository Vitalini/ebb-ai (1 stars, last pushed 9d ago), licensed Apache-2.0. It adds 164 tokens to every session and 1,907 once invoked, about $0.0007 per session on Opus 5.5. 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.
