## Tools (as reported by the server, not verified)

- `list\_strategies`: List the strategies published on brighter.fi, newest or best-performing first. Each carries its rebalance cadence, the assets it can hold, and its return over the chosen period against its benchmark. Strategies that can hold leveraged or inverse funds are excluded unless asked for.
- `get\_strategy`: One strategy in full: what its rule does, the parameters you can tune with their ranges and defaults, every asset it can hold, and its benchmark. Use the parameter keys with backtest\_strategy.
- `backtest\_strategy`: Run a published strategy over real market history with parameters of your choosing. Returns its figures against its benchmark. Values outside a parameter's range are snapped into it. This is a real backtest, so make each one count.
- `get\_allocation`: What a published strategy's rule holds right now, in basis points of the portfolio. This is the live target, computed from the latest close.
- `find\_assets`: Search the assets a Brighter strategy can hold — tokenized US stocks, ETFs and T-bills. A rule may only name a ticker that appears here.
- `asset\_history`: Daily closing prices for one asset over a calendar year, for checking a rule's premise against what actually happened.
- `dsl\_reference`: How to write a Brighter strategy: the language's blocks, indentation rules, indicators and limits. Read this before writing any rule — the language is small and specific, and guessing its syntax wastes a turn.
- `strategy\_schema`: The JSON schema for a strategy as an object, for when you would rather build the rule tree than write the text. check\_strategy and backtest\_code both accept text, which is usually easier.
- `check\_strategy`: Check a strategy written in Brighter's language: syntax, semantics, and whether every ticker it names is one Brighter can actually trade. Returns the faults with their line and column. Costs nothing and calls nothing upstream — check before you backtest.
- `format\_strategy`: Rewrite a strategy in the language's canonical form — the spelling Studio's editor shows. Useful for checking that what you wrote means what you think it means.
- `backtest\_code`: Run a strategy you have written against real market history and return its figures. This is a real backtest against real prices — not a simulation and not cached per call — so run it deliberately, after check\_strategy passes. Returns metrics only, never the curve.
