Seshat-BI: Skill for Claude Code

.claude/skills/dagster-orchestration-adapter/SKILL.md

dagster-orchestration-adapter is a skill for Claude Code from Kemetra/Seshat-BI. It costs 186 tokens per session (5,579 once invoked), scanned A, original, Apache-2.0.

An adapter for running an approved medallion data pipeline—the sequence of raw, cleaned, and prepared data steps—as a Dagster asset graph in unattended jobs or CI.

In plain words
What is it for?
Use it to schedule the medallion sequence in Dagster or CI, run only steps that have already passed their gates, and create derived run evidence.
Why use it?
It lets a scheduler run the existing approved steps without someone manually retyping them, while keeping approval gates and recording what ran.

This is Kemetra/Seshat-BI's own configuration. It tells Claude Code how to work on Seshat-BI itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Seshat-BI configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is `cd orchestration/dagster && uv venv .venv && uv pip install -p .venv -e "../..[dbt]" -e ".[dev]"`..

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

dagster-orchestration-adapter 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 11d 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-orchestration-adapter

  • Authority category (F024): Execution Adapter / DB-connected (NOT publish-capable; it TRIGGERS F016, it never publishes). The F024 enumerated declaration -- see docs/architecture/product-modules.md.
  • Roadmap feature: F030 On-disk spec: specs/024-dagster-orchestration-adapter (dir 024 == F030; when the dir number and the F-number disagree, the roadmap F-number wins).

Dagster is the unattended / CI RUNTIME for the medallion sequence: a scheduler / pipeline runs the asset graph so a human does not re-type each step. retail-orchestrate (F005) is the INTERACTIVE conductor of the SAME sequence; Dagster is its unattended sibling -- same medallion sequence, same gate-exit authority, same two human seams, neither self-approving. Tower BI (the gate exit code + the named human) is the brain; Dagster is the runner. This skill is how the agent reasons about running the medallion unattended without letting the orchestrator become the brain. You (the agent reading this) ARE the design surface; this skill is procedure, not an engine -- the engine, when built, is the separate Dagster project. See docs/decisions/0010-dagster-is-orchestration-adapter.md and docs/integrations/dagster-adapter.md.

STATUS: the Dagster PROJECT is BUILT (spec 134, activation slice of F030; the dbt engine seam is ACTIVATED per spec 135). orchestration/dagster/ exists -- definitions.py, the 11-asset graph, jobs, one STOPPED schedule, one STOPPED sensor, pyproject.toml pinning dagster==1.13.14 and bringing seshat-bi[dbt] (the dagster-dbt pin was dropped by spec 135 FR-011: it excludes dbt-core 1.12 and sits on no execution path) -- plus the seshat dagster doctor|run|evidence control layer. The OPERATIONAL procedure:

  1. seshat dagster doctor -- read-only preflight (project, its own venv under orchestration/dagster/.venv, the pinned dagster, the resolved build engine per table, per-table gate state, DSN present/absent). Blockers exit 2; the install remedy is cd orchestration/dagster && uv venv .venv && uv pip install -p .venv -e "../..[dbt]" -e ".[dev]".
  2. seshat dagster run --job <full_sequence_job|through_gold_job> [--table <table>] -- executes the graph as a shell-free child process in the orchestration venv. A failed/blocked gate halts downstream assets and exits 3 (the CI signal); report it with the recorded blocking_reason + named owner.
  3. seshat dagster evidence [--run-id <id>] -- list runs / render the committed record at orchestration/dagster/run-evidence/<run-id>.md.

Without DB credentials the DB-touching assets record a deferred boundary and block fail-closed -- report that truthfully; never fake a run.

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.
