Tools of Tomorrow Central: Cloud Cost Sentinel
	Description		Read-only	Idempotent	Open world
`compare_architectures`Price every shape that delivers a capability, and say where they cross over. This is the tool for "should we move to serverless", "is Lambda cheaper than EC2", "what would containers cost instead". Answer with the crossover, not a verdict: one shape is cheaper below some level of traffic and dearer above it, and the number where that flips is the thing the user can act on. `capability` is an id from `list_cost_building_blocks` (for example `serve-http`). `drivers` are the workload's measurements, and EVERY driver the capability declares must be given, for every shape. That is enforced rather than defaulted: giving one architecture a favourable assumption the other does not get is the single easiest way to produce a comparison that looks rigorous and is not. `over` names the driver to sweep, usually the one the user is unsure about (`requests_per_month` is the common one). Pass it to get `break_even`: a priced curve for each shape and the crossing points between them. `low` and `high` bound the sweep; omit them for the driver's typical range. Read `crossings` carefully. Each one carries the band around it where the two shapes are indistinguishable given the uncertainty in the inputs. Inside that band the honest answer is "it does not matter, pick on other grounds", and saying "X is cheaper" there is a claim the numbers do not support. An EMPTY `crossings` list is not "there is no break-even". Read `no_crossing`, which says which window was swept and what happened inside it. Usually it means one shape won at every point in that range, and that the answer is being decided by one of the drivers you held fixed rather than by the one you swept. Sweeping a different driver is what finds the flip. Do not report "they never cross" from a single sweep. Cost is one input and rarely the deciding one.

`compare_regions`Compare the same thing's price across AWS regions, cheapest first. Use this when a user asks where something is cheapest, or what moving a workload to another region would cost. `match` should be specific enough to identify one priced thing, for example `t3.medium` or `gp3`. `regions` limits the comparison; omit it to compare across every region the book covers. Regions where the thing is not offered are listed separately rather than silently dropped, because "not available there" is usually the more important answer. Region choice is rarely only about price. Data residency, latency to users, and which services exist in a region all matter, and this tool speaks to none of them. A cheaper region that cannot legally hold the data is not an option.	Compare the same thing's price across AWS regions, cheapest first.

`create_cloud_connection`Start linking a cloud account so it can be scanned. `provider` is "aws", the only provider supported today; `account_id` is the 12-digit AWS account number. `software` is the Tomorrow Central software the link is for; omit it for Cloud Cost Sentinel. Each software has its own read-only role, so link once per software. This is a two-party flow and you cannot finish it alone — creating the read-only IAM role requires the human's AWS credentials. Returns a `launch_url`. Hand the human these instructions verbatim: 1. Open the launch_url (a pre-filled CloudFormation quick-create link). 2. Review the read-only role it creates, then click Create stack. 3. Tell you when the stack says CREATE_COMPLETE. Then call `verify_connection` with the returned connection_id. Verification fails with a clear message until the role exists, so polling it every ~15 seconds is safe and expected. No ARN or secret needs to be copied by anyone.

`describe_workload`Price a workload described the way a person would describe it. Use this when the user does not know cloud: "a website with a database for my shop", "an API for my mobile app". They do not need to name a single AWS service, and you should not name any on their behalf before calling this. `text` selects an archetype from a closed catalogue by matching its declared keywords. It is never used to construct anything: it does not reach a label, a price, or any arithmetic. If nothing matches, the reply says so and lists what the catalogue does cover, which is a better answer than an invented one. You can also pass `archetype` directly from `list_cost_building_blocks`. It answers with no answers at all. Every question has a documented default, so a first reply always exists, with a wide range and every assumption listed. That is deliberate: a wall of questions before any number is what makes people give up. `answers` fills in what the user does know, in human units (visitors a month, pages per visit, photos uploaded), not cloud units. `how_we_got_the_numbers` shows each conversion from those units to the technical drivers, so the user can argue with a step instead of with the total. `open_questions` is ranked by how much answering each one would narrow the range, so ask the top one first and stop when the range is tight enough for the decision at hand. Do not ask all of them. `constraints` applies requirements before pricing, as `[{"constraint": "<id>", "value": "<value>"}]`. A location requirement here is reported as unmet, because this tool prices ONE region: use `where_can_this_run` for "where is this allowed to run". The reply also carries `architecture`, which is what was proposed and why, in plain words. Show it. A number with no visible shape behind it is not something a person can check.

`estimate_cost`Price a list of cloud components at real list prices. No account or signup. Use this when the user can name the pieces: "two m5.large servers, a Postgres database and a load balancer in Mumbai". If they cannot name the pieces, use `describe_workload` instead, which asks in units a person actually has. `items` is a list of `{"component": "<id>", "params": {...}}`. Get the ids and each component's parameters from `list_cost_building_blocks` and use them verbatim: a name you invent will be rejected, which is deliberate. `region` is an AWS region id such as `ap-south-1`. The reply is a RANGE, not a number: `monthly_total` has low, expected and high, because several inputs are genuinely uncertain and a single figure would hide that. `swing_factor` names the one input that most widens the range, which is the most useful sentence in the reply: it tells the user what to go and measure. `concentration` ranks the lines by share of the bill. `assumptions` lists every value that was defaulted rather than given, and `traps` lists costs this architecture usually incurs that the caller did not ask for, such as public IPv4 addresses or database storage billed apart from the database. `gaps` lists anything that could not be priced. It is never silently treated as zero. If a line is missing, the total is missing that line, and the gap says so. These are AWS on-demand list prices before any discount, credit or committed-use agreement, and they exclude tax. Treat the result as an upper bound on a real bill and never as a quote.

`get_job`Check the status of a Tomorrow Central job. Poll this after starting any scan. Status goes QUEUED → RUNNING → COMPLETED (or FAILED). A typical scan takes 1-3 minutes. The response's `poll_after_seconds` field is the minimum wait before polling again — respect it. Never start a second scan while one is RUNNING; the platform coalesces duplicates onto the in-flight job anyway (`coalesced: true`), and rate-limit errors include `retry_after_seconds` telling you exactly how long to back off.

`list_cost_building_blocks`Everything the estimator can be asked about, by name: a lookup, not an answer. Use this when you need the exact ids that `estimate_cost`, `compare_architectures` and `where_can_this_run` take and do not have them. They reject any name not listed here. `describe_workload` does not need it: it takes the user's plain words. Not as the answer to a question: it prices nothing and applies no requirement. One call per conversation is enough. Narrow it with `of` (`components`, `capabilities`, `archetypes`, `drivers`, `constraints`, `regions`), then go straight on to the tool that answers. Each entry carries the exact shape to pass it back in. Do not stop to ask the user for detail that the next tool defaults or that you can state as an assumption. If what the user described is not in here, say so plainly and say what IS covered. An estimate assembled from the nearest parts, presented as the thing they asked about, is worse than no estimate.

`list_cost_findings`Get the findings from a completed cost scan, newest analysis first. Call this once `get_job` reports COMPLETED. Returns, per finding: `kind` (e.g. nat_gateway, ebs_volume), `name` (the Name tag, falling back to the resource id), `region`, an advisory `verdict` with its display `verdict_label`, a heuristic `confidence` from 0 to 1, `est_monthly_savings` in USD, `recommended_action`, `evidence` (the observations behind the verdict, each naming what was measured and over what window), `monitoring_gaps` (what could NOT be observed), and `protected`. Plus the scan `summary`, `totals` and `account`. Note `name` is the only resource label returned; there is no separate ARN or resource-id field, so quote it verbatim when reporting rather than inventing an id. Optional `verdict` filter: "removable", "investigate", or "keep". How to read a finding — this matters, because the cost of being wrong is not symmetric: * Verdicts are ADVISORY. They are the scanner's reading of the evidence, not a decision. Present the evidence alongside the verdict and let the human decide. * "removable" means the evidence suggests nothing is using this resource. It is NOT an instruction to delete. Nothing in Tomorrow Central can delete anything, and you should not propose deletion commands unless the user explicitly asks. * "keep" and any finding with `protected: true` must never be presented as actionable. `protected` means a policy or retention tag covers the resource. * `confidence` is a heuristic score, not a probability. Treat anything below ~0.9 as "worth a human look", not "probably fine". * `monitoring_gaps` tells you what the scanner could NOT see (e.g. missing CloudWatch metrics).

`price_lookup`Look up current AWS on-demand list prices. No account, key or signup needed. Use this to answer "what does X cost", to sanity-check a bill, or to price a design before building it. Prices come from AWS's own published price files and are refreshed on a schedule; the reply carries the book version so you can say how current the number is. `service` is one of the names from `list_priced_services` (for example `ec2`, `rds`, `s3`, `lambda`, `ebs`, `data_transfer`, `nat_gateway`). `region` is an AWS region id such as `ap-south-1` or `eu-west-1`. `match` narrows within a service and is the parameter you will use most: pass `t3.medium` for one instance type, `gp3` for one volume type, or leave it empty to see everything that service publishes in that region. Matching is a plain substring against the rate's dimensions, so partial values work. `quantity` selects the pricing band for anything billed in tiers, which includes S3 storage, data transfer out and Lambda duration. Pass the monthly amount in the rate's own unit (GB, GB-seconds) to get the band that amount actually falls in. Leaving it at 0 gives the first band, which OVERSTATES the cost of large volumes: egress at 500 TB is materially cheaper per GB than at 100 GB. These are list prices before any discount, private pricing, credit or committed-use agreement, and they exclude tax. Treat them as an upper bound on a real bill. If nothing matches, the reply says so and lists what that service does publish in that region, so you can correct the term rather than guess again.	Look up current AWS on-demand list prices.

`report_feedback`Report, in plain English, something Tomorrow Central could not do, did badly, or documented unclearly. Use this when you hit a wall: a capability that does not exist, a call that succeeded but returned something you could not use, a tool description that did not match what happened, or a bug. `kind` is one of: bug, missing_capability, unclear_docs, wrong_result, suggestion, other. `blocking` means this stopped you completing what the user asked for. `tool_name` and `job_id` anchor the report to a specific call if there was one, and `rating_token` links it to a result you were given. Say what you were trying to do and what happened instead. Do not paste credentials, and remember that anything you write here is stored. One call per issue. The reply may tell you the gap is already known or already fixed, in which case retrying is worth it. Nobody replies to this in conversation: it is a one-way channel, so do not promise the user a response.

`run_cost_scan`Start a cloud cost / FinOps scan of a linked account and return a job_id. Use this when the user wants to find idle, unused or underutilized cloud resources, review cloud spend, or estimate savings. The provider comes from the connection, and AWS is the only provider supported today (see `list_connections`). Other clouds will appear on this same tool as connections for them become linkable; nothing else about the call changes. READ-ONLY against your cloud: it reads resource metadata and monitoring metrics and reports; it never changes, stops or deletes anything. (It does create a scan job here and consume that account's scan quota, which is why this tool is not marked read-only.) On AWS it covers EC2 instances, EBS volumes and snapshots, RDS instances, Elastic IPs, NAT Gateways, load balancers, VPCs and VPC endpoints, site-to-site VPN and Transit Gateway attachments, Client VPN endpoints, Secrets Manager secrets, CloudFront distributions and WAF web ACLs. Resource kinds outside that list are not inspected, so a clean scan is not a claim that the whole bill is optimized. `connection_id` picks which linked AWS account to scan (see `list_connections`). Omit it to run against sample data — useful for showing the user what the output looks like before any account is linked. The scan runs asynchronously: poll `get_job(job_id)` roughly every 10 seconds until status is COMPLETED (typically 1-3 minutes), then call `list_cost_findings(job_id)`. Do NOT start another scan while one is running — each scan consumes the account's monthly quota. Pass `idempotency_key` (any unique string you choose) if you may retry on a network error: a retry with the same key returns the original job instead of starting a second scan.

It does not import or index anything; use search_start_import next. The person confirms before it runs. Nothing happens until the person confirms: this returns a summary and a code for tc_confirm.

`search_start_import`Starts crawling one of your organization's VERIFIED websites into a Search project. mode 'preview' reports what an import would contain and changes nothing; mode 'import' REPLACES the project's catalogue with what is found. Takes minutes; check progress with search_import_status. Only one import runs at a time. The person confirms before it starts.

`submit_rating`Rate a result you were given, from 1 (useless) to 5 (exactly what was needed). `rating_token` comes back alongside the result itself, from get_job_result or list_cost_findings. Do not construct one: a token you invent will be rejected. Each token can be rated once. A low rating is more useful than a high one, so rate honestly rather than kindly. Add a `comment` saying what was wrong; without one, a low score says nothing actionable. For anything that needs a fix rather than a score, use report_feedback.

`verify_connection`Check whether the read-only role for a connection exists yet and mark it VERIFIED if so. Expect this to fail while the human's CloudFormation stack is still creating — that's normal, not a misconfiguration. Retry every ~15 seconds for up to ~5 minutes before reporting a problem.

`where_can_this_run`Apply requirements FIRST, then price only the regions that survive. Use this when the question is WHERE something may or should run (data residency, a jurisdiction to avoid, near its users, surviving a zone failure), with or without what it would cost. Not for pricing one region already chosen: that is `estimate_cost`, or `describe_workload` for a workload in plain words. `items` (the `estimate_cost` shape, not empty) and `constraints` (`[{"constraint": "<id>", "value": "<value>"}]`) take ids from one `list_cost_building_blocks` call with `of=["components", "constraints"]`, then come straight here. If a location value is refused, the error lists the valid values: retry with one of those. The user does not have to describe the workload first. Location requirements decide which regions are allowed whatever the architecture, so pass the smallest one that fits what they said and state it as an assumption. An architecture requirement (zone failure) applies only to the components you pass: read `changes` and `unmet`, and never report anything in `unmet` as met. Only requirements in the catalogue's `constraints` are checked. `users_near` narrows to a broad area such as `emea`, not to a latency figure: for a millisecond target, say plainly that it was not checked. `options` are allowed regions that price every line, cheapest first. `cannot_run_this` are allowed but do not sell part of it. `excluded` failed a requirement, each with the reason. `cost_of_requirements` splits the premium into location and the architecture changes it forced.
