What is prefect-alerts-to-orchestra?

A mapping guide for moving notifications from Prefect to Orchestra. Prefect is a workflow tool for running data or automation pipelines, while Orchestra is a platform that represents those notifications as alerts.

Use it when converting Prefect flow or task hooks, automation notifications, or webhook blocks into Orchestra alert configurations.

The two systems use different names and structures for events such as a failed, completed, crashed, or cancelled flow or task. This guide shows how those events map to destinations such as Slack, email, PagerDuty, Microsoft Teams, webhooks, and Datadog.

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	$0.00108	$0.01882
Opus 5.5	$0.00043	$0.00753
Sonnet 5.5	$0.00022	$0.00376
Haiku 4.5	$0.00011	$0.00188

Security

Grade A, and why

prefect-alerts-to-orchestra scanned grade A with 1 finding 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 2mo 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.

Overview

Prefect notifications live in three places: @flow(on_failure=...) / @flow(on_completion=...) hooks, @task(on_failure=...) hooks, and Prefect Automation notification actions. All three map to Orchestra's alerts: block, placed at pipeline level (for flow-level hooks) or task level (for task-level hooks). Orchestra supports six destination integrations: SLACK, EMAIL, PAGER_DUTY, MICROSOFT_TEAMS, WEBHOOK, and DATADOG.

Parameter Mapping

Prefect construct	Orchestra field	Notes
`@flow(on_failure=[slack_hook])`	`statuses: [FAILED]` + SLACK destination	pipeline-level `alerts:`
`@flow(on_completion=[slack_hook])`	`statuses: [SUCCEEDED]` + SLACK	pipeline-level
`@flow(on_crashed=[hook])`	`statuses: [FAILED]`	no CRASHED status in Orchestra
`@flow(on_cancellation=[hook])`	`statuses: [CANCELLED]`
`@task(on_failure=[hook])`	task-level `alerts:` on that specific task
Prefect Automation → Slack notification	`statuses: [FAILED/SUCCEEDED]` + SLACK
Prefect Automation → email notification	`statuses: [...]` + EMAIL
Prefect Automation → PagerDuty action	`statuses: [...]` + PAGER_DUTY	requires `connection_id`
Prefect Automation → Teams notification	`statuses: [...]` + MICROSOFT_TEAMS	requires `connection_id`
`SlackWebhook.load("x").notify(...)`	SLACK destination with `destination` field	channel from `notify(channel=...)`
`MicrosoftTeamsWebhook.load("x").notify(...)`	MICROSOFT_TEAMS with `connection_id`

Valid statuses values: FAILED, SUCCEEDED, CANCELLED, WARNING, SKIPPED

Destination rules:

SLACK and EMAIL → require destination field (channel or address)
PAGER_DUTY, MICROSOFT_TEAMS, WEBHOOK, DATADOG → require connection_id (Orchestra connection name with 5-digit suffix)

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.
