Fable review
Fable is the judgement lane, for the calls that are genuinely hard: which of two architectures survives contact, whether a plan's premise holds, whether an interface reads the way its author thinks it does. Use it sparingly and on questions where a second opinion changes what you do next.
What comes back is a set of leads. Verify each one before acting on it.
Choosing the lane
Three review skills send a brief to an outside model, chosen by the kind of question rather than its importance:
| The question | Lane |
|---|---|
| A bounded check against criteria the brief states: a contract, a spec, copy against a style guide | glm-review - cheap |
| An answer the repository can settle: what changed when, whether a diff does what it claims, where it breaks | astra-review - frontier, runs read-only commands |
| A judgement call with no checkable answer: architecture, taste, a plan, with the evidence in the brief | fable-review - frontier, reads files only |
A routine correctness pass over a diff is the host's own code review, not a lane.
