Seshat-BI: Instructions file for Codex

AGENTS.md

Seshat-BI AGENTS.md is an instructions file for Codex, OpenCode from Kemetra/Seshat-BI. It costs 1,963 tokens per session, scanned A, original, Apache-2.0.

Repository-specific operating instructions for Seshat BI, including its staged readiness process and rules for agent-led work. Readiness means proving each project stage is complete before moving to the next one.

In plain words
What is it for?
Use them when running Seshat BI workflows, checking readiness, handling database setup, or preparing work for human approval.
Why use it?
They prevent agents from skipping required checks, making unsupported business assumptions, or treating a static check as proof that the analytics work is correct.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is Kemetra/Seshat-BI's own configuration. It tells Codex and OpenCode 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 →

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

Seshat-BI AGENTS.md 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 20d 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.

AGENTS.md -- operating rules for agents in this repo

Seshat BI is agent-first: you (the agent) are the interface; the CLI gates (seshat check, retail validate) are helpers you CALL, never the product. This file is the short operating contract. The full law is .specify/memory/constitution.md; the spine is docs/readiness/readiness-model.md.

Naming. The product is Seshat BI (package alias Seshat_BI). It was previously developed under the internal name Tower BI Agent Kit; the governance spine is still the Readiness System. Same product, one brand.

Decide from readiness state

  • Read the table's readiness status (templates/readiness-status.yaml shape) to find current_stage and next_action. Launch the workflow for THAT stage only -- never skip ahead.
  • The seven stages, in order: Source -> Mapping -> Silver -> Gold -> Semantic Model -> Dashboard -> Publish. A stage is entered only when the prior is pass.
  • The retail-orchestrate conductor sequences the verbs; the readiness status records the state. Recompute current_stage from committed artifacts + Gate status + migration presence -- there is no separate run-state engine.

Hard stops (never cross these)

  • Do NOT proceed to silver when mapping_ready is blocked (or Gate status is not CLEARED). No silver.* SQL before an approved map (Principle IV).
  • Do NOT point Power BI at gold before retail validate passes (Principle VIII).
  • Do NOT design dashboards before metric contracts exist (roadmap rule 5).
  • Do NOT run the Power BI execution adapter on your own initiative (the official Power BI MCP / connection; pbi-cli no longer the preferred path) -- feature 016, gated on semantic_model_ready (Principle II). It is EXECUTION-ONLY (it cannot define metrics, mappings, semantic logic, or dashboard design), and no readiness stage depends on it. Since ADR 0018 (ratified 2026-08-18) the LOCAL slice ships: seshat pbi-mcp plan-write / apply run only against a target and operation RESOLVED from the committed allowlist, never free-form, and only when the owner asks for that write. The REMOTE slice remains deferred and owner-gated. Reaching for either unasked is still a hard stop -- a shipped verb is not a standing authorization.
  • Do NOT self-grant an approval. Approvals are named human actions (Principle V): grain, PII publish-safety, business rollups, sentinel-vs-null.

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.
