cost-optimize-plan

cost-optimize-plan is a skill for Claude Code, Codex from culiops/culiops-agent. It costs 145 tokens per session (9,162 once invoked), scanned A, original, MIT.

A read-only planning guide that turns a cloud-cost investigation report into a staged list of possible savings actions. It checks each action for reversibility, impact, evidence of non-use, and dependencies.

In plain words
What is it for?
It helps validate waste findings, rank remediations into action tiers, estimate verification needs, and prepare a plan for an operator to carry out separately.
Why use it?
It prevents cost recommendations from being acted on without verifying their evidence and possible side effects. It does not make changes or execute the plan.

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

cost-optimize-plan 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.

Cost Optimize Plan

Given a cloud-cost-investigate report, run a read-only per-action verification pass, triage each remediation across four dimensions (reversibility, blast radius, evidence of no-use, dependency footprint), and produce a tiered execution plan. Strict read-only Iron Law; per-batch operator approval for verification queries; no handoff to execution — operator drives iac-change-execution manually with the plan.

The Iron Law

NO MUTATIONS. EVER.
NO VERIFICATION QUERIES WITHOUT OPERATOR APPROVAL.
NO TIER ASSIGNMENT WITHOUT EVIDENCE.
NO HANDOFF TO EXECUTION — OPERATOR DRIVES.
  • Law 1: Read-only. Cost APIs, resource-state APIs, metrics APIs, access-log queries only. No delete / terminate / update / tag — not even "harmless" ones.
  • Law 2: Per-batch verification approval. All verification queries for the report are planned together, itemized with IAM perms + per-query API cost, and approved as one batch before any run.
  • Law 3: Every tier assignment carries evidence. No item lands in 🟢 or 🚫 without a labelled signal — the verification result row points at the specific query and its output. Same discipline as cloud-cost-investigate's source-labelled savings.
  • Law 4: Skill stops at the plan. Even when an item is 🟢 Fast win and the operator says "just run it" — the skill refuses. Operator opens iac-change-execution separately. Avoids skipping the per-change pre-flight gate.

Constraints (Non-Negotiable)

  1. Read-only. No mutations of any kind.
  2. Per-batch query approval. All verification queries pass GATE 2 as a single batch with IAM + cost itemization. No silent extensions.
  3. No playbook → manual review. Items whose (cloud, action-type, resource-type) has no examples/<cloud>/<action>.md playbook are marked manual-review-required and parked in a dedicated section of the plan. Skill never invents a verification strategy on the fly.
  4. Evidence required for every tier. No 🟢 / 🚫 without a verification signal. If a query failed, the item stays in 🔴 with verification-incomplete evidence — never silently promoted.
  5. Single report per run. Skill runs against one cloud-cost-investigate report at a time. Combining reports across accounts / time ranges is out of scope.
  6. Catalog re-use, not re-fetch. Service-discovery catalog is consulted (if present) for dependency lookup — never re-discovered.
  7. Output: .culiops/cost-optimize-plan/<scope-slug>-<YYYYMMDD-HHmm>.md. Scope-slug matches the upstream report's slug, so plan files line up next to the investigation they triage.
  8. Stop on query failure. Auth errors, rate limits, throttling halt the run and surface to operator. The skill does not silently skip and produce a partial plan disguised as complete.
  9. No re-evaluation of savings. Upstream report's savings/source/confidence are copied verbatim into the plan. This skill adds safety/triage columns alongside.
  10. No handoff automation. Plan ends at GATE 3 commit. Even a single fast-win item does not trigger iac-change-execution automatically.

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.
