Conversation
The deny reason is the gate's only channel to the blocked agent, and it read as bureaucracy to an agent that had already run the skill earlier in the same session — enough that a main agent proposed filing a bug to make the flag survive the turn. Per-turn re-gating is deliberate (turn-state-reset.sh: 'an invariant satisfied last turn says nothing about this one'), so the message now states the scope and the reason, and points at carrying prior findings in the skill args instead of re-researching from scratch. Behavior unchanged; only the reason string. gates.bats pins the HOW-DO-I-GATE prefix, which is preserved.

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Assert the updated denial reason in Bats.
The fail-open path is covered. Extend the denial test to assert both per-turn gating and passing prior findings as skill arguments.

Source: Path instructions
…deny message, pin per-turn text The deny message told a blocked agent to paste prior findings into the skill args and "ask only what is new" because the skill is "cheap when there is little left to research." All three claims are false: the skill binds $ARGUMENTS to a one-line goal restatement, its retrieval loop explicitly forbids narrowing on a prior digest, and its cost (3-4 Bash calls) is a floor independent of caller knowledge. Replaced with a true cost-reassurance beat grounded in the skill's own stated budget. Also adds a bats assertion pinning the per-turn-scope sentence itself (not just the HOW-DO-I-GATE header), since nothing previously asserted on the PR's actual payload text — a later trim could have silently reverted it with a green suite. RED/GREEN-verified by temporarily mutating the pinned text and confirming the new assertion fails.

Problem
The how-do-i gate's deny reason is the only channel it has to the agent it just blocked. It currently says what to do but not why the block is legitimate:
To an agent that ran the skill twenty minutes ago in an earlier turn of the same session, that reads as redundant bureaucracy. Observed failure: a main agent (me) took an am-i-done reviewer follow-up to file an issue arguing the gate should recognize an earlier same-session run — i.e. proposing to break the invariant, because nothing at the point of denial explained it.
Reading the source settled it the other way.
turn-state-reset.sh:That is correct and load-bearing, and this session is a concrete case: the "redundant" re-run is what routed a generic
gh issue closetoproc.github.close-stale-issue, without which the merge-verify and evidence steps would have been skipped.Change
Reason string only — no behavior change. It now states the per-turn scope and the reason, and points at the cheap path (carry prior findings in the skill args, ask only what is new) rather than implying a full re-research. A code comment above the string records why it carries that weight, so it is not trimmed back later as verbose.
