Roborev Lookahead Review

roborev-lookahead-review

Request a time-series look-ahead review for a commit and present the results. A look-ahead review checks whether the change uses information that would not yet be available at the point in time it represents — also called peekahead, future leakage, or temporal leakage.

Usage

$roborev-lookahead-review [commit] [--panel <name>|none]

Explicit invocation only

Invocation must be explicit: literal personal $roborev-lookahead-review, plugin $roborev:roborev-lookahead-review, or structured Codex skill selection. Requests such as “check this commit for peekahead” without one of these explicit mechanisms must use native behavior and must not run roborev.

Sandbox access

roborev uses a local daemon. If a command fails with permission denied, the sandbox may be blocking access to its loopback port or Unix socket. Retry the same command with sandbox_permissions: "require_escalated". Do not start or restart the daemon because a sandboxed status probe cannot reach it.

When NOT to invoke this skill

Do NOT invoke this skill when the user is presenting or pasting existing review results. Messages that contain review findings, verdicts, or summaries are outputs — not requests to start a new review.

IMPORTANT

This skill requires you to execute bash commands to validate the commit and run the review. The task is not complete until the review finishes and you present the results to the user.

These instructions are guidelines, not a rigid script. Use the conversation context. Skip steps that are already satisfied. Defer to project-level AGENTS.md instructions when they conflict with these steps.

Instructions

When the user invokes $roborev-lookahead-review [commit] [--panel <name>|none]:

1. Validate inputs

If a commit ref is provided, use the commit-provided command snippet below; it stores and validates the ref before invoking roborev review.

If validation fails, inform the user the ref is invalid. Do not proceed.

2. Build and run the command

Construct and execute the review command:

If no commit is specified, run:

roborev review --wait --type lookahead [--panel <name>|none]

If a commit is specified, run:

read -r commit <<'ROBOREV_REF'
<commit>
ROBOREV_REF
git rev-parse --verify -- "$commit^{commit}" || exit 1
roborev review "$commit" --wait --type lookahead [--panel <name>|none]

• If --panel <name> is specified, include it (fans out to the named config panel); --panel none forces a single-agent review

The --wait flag blocks until the review completes.

3. Present the results

If the command output contains an error (e.g., daemon not running, repo not initialized, review errored), report it to the user. Suggest roborev status to check the daemon, roborev init if the repo is not initialized, or re-running the review.

Otherwise, present the review to the user:

• Show the verdict prominently (Pass or Fail)
• If there are findings, list them grouped by severity with file paths and line numbers so the user can navigate directly
• If the review passed, a brief confirmation is sufficient

Panels (multi-reviewer reviews)

If you pass --panel <name>, or a default_panel is configured for explicit reviews, the review fans out to a panel of reviewers. In that case the Enqueued job <id> is the synthesis (parent) job that aggregates them, and its verdict and findings are the synthesized result across the whole panel. Present that synthesized verdict/findings, and offer fix on that parent id — never an individual reviewer. roborev show prints a one-line reviewers summary (e.g. 3 reviewers: bug P, security F) for a synthesis job. --panel none forces a single-agent review, and automatic post-commit hook reviews stay single-agent regardless of default_panel.

4. Offer next steps

If the review has findings (verdict is Fail), offer to address them:

• "Would you like me to fix these findings? You can run $roborev-fix <job_id>"

Extract the job ID from the review output to include in the suggestion. Look for it in the Enqueued job <id> for ... line or in the review header. For a panel review this id is the synthesis parent.

If the review passed, confirm the result and do not offer $roborev-fix.

Examples

Default look-ahead review of HEAD:

User: $roborev-lookahead-review

Agent:

1. Executes roborev review --wait --type lookahead
2. Presents the verdict and findings grouped by severity
3. If findings exist: "Would you like me to address these findings? Run $roborev-fix 1042"
4. If passed: "Look-ahead review passed with no findings."

Look-ahead review of a specific commit:

User: $roborev-lookahead-review abc123

Agent:

1. Validates: git rev-parse --verify -- "abc123^{commit}"
2. Executes roborev review abc123 --wait --type lookahead
3. Presents the verdict and findings
4. If findings exist: "Would you like me to address these findings? Run $roborev-fix 1043"
