AgentStateDeveloper

Ask why a function exists and the answer is in a Slack thread, a closed PR, or nobody’s head. An agent opening the file cold has none of it, and a diff shows what changed rather than what the change means.

Every symbol gets a decision ledger, an effect declaration and a place in the call graph — stored in a git-native sidecar, so the reasoning clones with the repo and survives renames and file moves.

• Decision ledger — hazards, rationale and authority per symbol
• Effect declarations that propagate through the call graph, so blast radius is computable rather than guessed
• Call graph — callers, callees and transitive reach
• Policy gates that require sign-off before agent writes to sensitive paths
• Hash-chained audit log — tamper-evident, replayable, independently verifiable
• Agent thinking captured alongside the code it produced
