Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00098 | $0.02284 |
| Opus 5 | $0.00049 | $0.01142 |
| Sonnet 5 | $0.00020 | $0.00457 |
| Haiku 4.5 | $0.00010 | $0.00228 |
Grade A, and why
dagster-definitions-to-orchestra 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 12d 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.

Dagster Definitions / Job Structure -> Orchestra Pipeline Root
Overview
A Dagster project is described by a Definitions object that groups assets, jobs, schedules, sensors, and resources. Scheduling, retries, concurrency, and timeouts are set on jobs (via tags and RetryPolicy) and on ScheduleDefinition objects. None of these map to individual Orchestra tasks — they map to root-level fields on the Orchestra pipeline YAML. Apply this skill first, before any asset/op-level conversion, to establish the correct pipeline skeleton.
A useful rule of thumb: one Dagster job (or one cohesive asset selection driven by a schedule) -> one Orchestra pipeline.
Field Mapping Reference
ScheduleDefinition / @schedule -> schedule:
| Dagster | Orchestra | Notes |
|---|---|---|
cron_schedule="0 2 * * *" |
cron: '0 2 * * ? *' |
Dagster's cron is standard 5-field — convert to Orchestra's 6-field AWS EventBridge cron, do NOT copy verbatim |
cron_schedule="@daily" |
cron: '0 0 ? * * *' |
Expand shorthand, then convert to 6-field |
execution_timezone="Europe/London" |
timezone: Europe/London |
IANA timezone |
ScheduleDefinition(job=...) |
one schedule: entry |
The schedule targets a job -> the pipeline |
@schedule returning RunRequest(run_config=...) |
schedule[].run_inputs |
Map run config values to inputs |
| no schedule (manual / sensor only) | (omit schedule:) |
Use webhook: {enabled: true} or sensors:/trigger_events: |
Orchestra requires a 6-field AWS EventBridge cron (minute hour day-of-month month day-of-week year), not Dagster's standard 5-field cron_schedule. Exactly one of day-of-month/day-of-week must be ?. Passing a 5-field string fails validation with "Incorrect number of values ... 6 required, 5 provided."
Orchestra ScheduleModel:
schedule:
- cron: '0 2 * * ? *'
timezone: UTC
name: nightly
run_inputs: {}
exclude: []

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.

dagster-definitions-to-orchestra is a skill published in the GitHub repository orchestra-hq/orchestra-skills (9 stars, last pushed 3d ago), licensed MIT. It adds 98 tokens to every session and 2,284 once invoked, about $0.0005 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 2026-08-31.
