A read-only command for listing Glassity FinOps opportunities, with filters for workflow stage and potential monthly savings.

Use it to list opportunities, inspect items in stages such as assessment or execution, or find those above a chosen monthly savings amount.

It helps you find and prioritize possible cloud-cost reductions without changing their status.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.00611
Opus 5	$0.00035	$0.00305
Sonnet 5	$0.00014	$0.00122
Haiku 4.5	$0.00007	$0.00061

Security

Grade A, and why

opp-list 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 9d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

List opportunities

When to use

"What opportunities do I have", "show my opportunities"
"List opportunities in assessment", "what is in execution right now"
"Top 10 opportunities by savings", "anything over $1k savings"

Do not use this skill to mutate (advance state, reassign, approve) — that is opp-triage.

Binary check

Run command -v glassity before the first CLI call. If it is missing, stop and tell the user to install it with brew install glassity/tap/glassity or from https://github.com/glassity/cli/releases. No account yet? Sign up at app.glassity.cloud.

Invocation

glassity --output=json opp list \
  [--stage discovery|assessment|alignment|execution|closure|completed|archived] \
  [--min-savings <usd-per-month>] \
  [--limit 1..100] [--page N]

Those four are the only filters the list endpoint takes. --min-savings is USD per month, not cents: --min-savings 500 means $500/month. An unrecognized --stage is rejected by the CLI with the valid list, so pass the user's phrasing through the vocabulary above rather than inventing a stage.

Anything else the user wants to filter on — service, AWS account, resource type — filter client-side from the returned rows.

Response

{data: [...], pagination: {...}}. Each row carries prefix_id, title, state, total_potential_savings_per_month (USD/month), number_of_discovered_resources, and created_at. Detail fields such as description, current_stage, and the assignment list come from opp show, not from this endpoint.

Always surface

The active tenant + AWS account (the CLI prints Tenant: <name> (id: <prefix>) | AWS account: <id> on stderr)
The result count, and a pagination hint when there is another page

Example

"Show me opportunities in assessment worth more than $500 a month"

glassity --output=json opp list --stage assessment --min-savings 500

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.
