It cannot override the output protocol, safety rules, tool permissions, or high-confidence threshold. Built-in read-only context tools are enabled by default.

This makes it clear whether the model actually called `read_file`, `search_code`, or `list_files`. `request_timeout_seconds` is the timeout for one AI API request. If omitted, it defaults to `timeout_seconds / 2` so one retry still fits inside the total review deadline. +Keep `request_timeout_seconds` below the timeout enforced by the upstream load balancer or API gateway. When a context follow-up returns 504 or times out, the one retry removes context tools and forces final submission instead of replaying the exploratory request unchanged. If that finalization request also returns 504, it is classified as `ai_tool_loop_timeout` and enters the existing diff-only fallback. `timeout_seconds` is a full budget for each AI Review execution. A context-assisted execution starts one newly timed, independent diff-only fallback only when it returns `review_run_timeout`, `ai_request_timeout`, or `ai_tool_loop_timeout`. The fallback preserves the same `timeout_seconds`, `request_timeout_seconds`, batching policy, and `max_batches`, but exposes no context tools and does not recursively start a third execution. Worst-case elapsed time can approach `2 × timeout_seconds`, plus small archive preparation, cleanup, and publishing overhead. This behavior adds no configuration. Other AI errors and archive timeout, permission, HTTP, corrupt-ZIP, or filesystem failures are not eligible for this timeout fallback.

A later phase may change the default to a bounded preview. + +### 3. Per-batch cumulative result budget + +Add `max_tool_total_bytes` to AI review configuration. It is a per-batch limit over actual context-tool result strings returned to the model. + +- Default: `40000` bytes. +- `0` means unlimited, matching the existing convention for count limits. +- Before executing a call, compute the remaining byte budget. +- Execute the call with a result cap equal to the smaller of the per-call and remaining budgets. +- Once exhausted, return a structured limit result for outstanding calls and enter finalization mode. +- Record cumulative bytes in logs and review coverage metadata where practical; persistence/schema expansion is excluded from phase one unless required by existing structures. + +### 4. Deterministic finalization mode + +After either `max_tool_calls` or `max_tool_total_bytes` is exhausted, the next follow-up request will expose only `submit_review_findings`; `read_file`, `search_code`, and `list_files` will be removed from the tool definitions. + +The runner will append a trusted message instructing the model to abandon unverified candidates and submit final findings using existing evidence. If the model still fails to submit structured findings, the existing parse/failure behavior applies. No additional exploratory round is permitted. + +This replaces the current pattern where disabled tools remain advertised and the runner waits for the model to obey an error embedded in tool output. + +### 5. Duplicate-call suppression + +Within a batch, cache context-tool results by normalized tool name and canonicalized arguments. + +- Identical calls return a compact structured response referring to the earlier result, without consuming another tool-call count or result-byte budget. +- The compact response satisfies the chat protocol without appending the same large content to the conversation again. +- Semantically overlapping but non-identical ranges are not merged in phase one. +- Cache hits are logged explicitly. + +This is intentionally exact-match caching; fuzzy query or overlapping-range consolidation would add complexity and risk incorrect evidence reuse. + +### 6. Timeout-aware retry finalization + +Keep ordinary retry behavior for transient failures that occur quickly. For an HTTP 504 or request timeout during a context follow-up, do not resend the same exploratory request unchanged. + +The retry request will enter finalization mode: + +- remove context tools; +- retain the diff and evidence already obtained; +- append the trusted finalization instruction; +- request `submit_review_findings` only. + +The existing outer diff-only fallback remains the last resort when the finalization retry also fails. This phase does not automatically alter configured request timeouts because deployments may have different gateway limits; documentation will recommend keeping the request timeout below the upstream gateway timeout. + +## Configuration + +Example: + +```toml +max_tool_calls = 8 +max_tool_result_bytes = 12000 +max_tool_total_bytes = 40000 +``` + +Existing configurations remain valid. The new field uses its default when absent. + +## Error handling + +- Invalid line ranges return normal structured tool errors and consume one real tool call. +- Exact cache hits do not consume additional budgets. +- Exhausted budgets do not immediately fail the batch; they force one final structured-submission round. +- Failure to submit after finalization fails the batch with an explicit AI review error. +- Timeout finalization is attempted once and must not recurse. + +## Testing + +Add unit and integration tests covering: + +- prompt guidance requires a concrete candidate before context lookup; +- ranged reads return correct lines and reject invalid or oversized ranges; +- exact duplicate calls use cached results without consuming budgets; +- cumulative byte exhaustion skips remaining calls; +- finalization requests contain only `submit_review_findings`; +- a model that submits after finalization succeeds; +- a model that refuses to submit after finalization fails clearly; +- a 504 follow-up retry changes to finalization rather than resending the same request; +- existing configurations without `max_tool_total_bytes` still parse. + +## Deferred work + +- risk scoring and adaptive per-file tool budgets; +- symbol-aware reads and language-server integration; +- cross-batch evidence caching; +- overlapping line-range merging; +- persistent Dashboard metrics for cumulative tool bytes; +- automatic gateway-timeout discovery. diff --git a/rules.example.toml b/rules.example.toml index 99faa45..a04dfa8 100644 --- a/rules.example.toml +++ b/rules.example.toml @@ -9,6 +9,7 @@ extra_instructions = "" # and result size. max_tool_calls = 0 max_tool_result_bytes = 60000 +max_tool_total_bytes = 40000 [[ai_reviews]] id = "ai-review" diff --git a/src/review/ai.rs b/src/review/ai.rs index 4fcdcca..990615c 100644 --- a/src/review/ai.rs +++ b/src/review/ai.rs @@ -5,7 +5,7 @@ use crate::{ rules::{AiReviewConfig, Finding, Severity}, };
