id-baseline

id-baseline is a skill for Claude Code, Codex from lukasrepublic/agentic-foundry. It costs 191 tokens per session (2,455 once invoked), scanned A, original, MIT.

A read-only adoption procedure for an existing OpenTofu or Terraform repository. It compares that code with the live environment and accepts the baseline only when the plan shows no differences.

In plain words
What is it for?
Use it when adopting an existing infrastructure-as-code repository, validating that it is drift-free, and recording the result of that check.
Why use it?
It helps take ownership of existing infrastructure code safely by checking whether it already matches reality. It reports drift but never applies changes or reconciles the environment automatically.

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

id-baseline 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 5d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

id-baseline — read-only adopt-existing-IaC craft (infra-delivery step 2, ★ entry mode)

The infra-delivery step sequence (a documented procedure this skill family forms — no workflow engine or state-machine file ships) drives an infra change → merge. Step 2 has four entry modes, one per starting condition. id-baseline is the entry mode for "an IaC repo already exists" — the operator points at an existing OpenTofu/Terraform repo and adopts it. Unlike id-import (greenfield — codify live infra that has NO IaC), id-baseline adopts an existing repo and validates it is drift-free against the live environment. The procedure the generic agent runs: point at the existing IaC root, resolve the active stack profile, run the acceptance seam infra_binding.plan read-only and require the plan empty, then produce the drift-free / drift REPORT and record the observation. The acceptance seam is tofu plan == ∅ — an empty plan means the IaC equals reality (the adoption is clean, which doubles as the forever drift check). It NEVER applies and NEVER auto-reconciles — adoption is read-only validation, proven by the empty diff; drift is surfaced, never fixed.

ADVISORY — not a gate, no machine-adjudicated GREEN verdict

This skill is ADVISORY. It produces a baseline/drift report + a .foundry/-partitioned drift step-report note; it does NOT gate, approve, or block any merge. Crucially, adoption VALIDATES — it is not a change being delivered through a merge process — so id-baseline does NOT claim a machine-adjudicated GREEN verdict (mirroring id-verify/id-plan, which are advisory and not-self-certified). The empty-plan signal is the REPORT (drift-free / drift), recorded as a plain step-report note for the operator + the id-drift/id-rollback consumers — NOT an automated PASS. Honest disclosure: the bespoke emit_infra_walk_evidence recorder this note used to be written through does not exist in scripts/ — retired.

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.

id-baseline is a skill published in the GitHub repository lukasrepublic/agentic-foundry (1 stars, last pushed today), licensed MIT. It adds 191 tokens to every session and 2,455 once invoked, about $0.0010 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.
