This report synthesizes these findings and provides +a structural protocol to break the recursive failure loop. + +--- + +## 1. Core Failure Dimensions + +### A. The "Test vs. Build" Blind Spot + +The most frequent cause of "false positives" is the agent running unit tests +while ignoring the build pipeline. + +- **Vitest Lenience:** Vitest uses `esbuild` to transform TypeScript, which + often ignores type errors that don't directly prevent code execution. +- **CI Strictness:** GitHub Actions run `tsc --build` as a blocking step. PR + 21212 failed 20+ times because the agent saw green tests but missed cascading + TypeScript inference errors (Promise flattening) that only surfaced during a + full build. +- **OS Drift:** Snapshots were generated on macOS using `MAC_TERMINAL_ICON`, + which automatically failed on Linux/Windows CI runners using `DEFAULT_ICON`. + +### B. UI Layout Side-Effects + +Changes to persistent UI components (Header/Footer) frequently broke integration +tests in non-obvious ways. + +- **The "Off-Screen" Prompt:** In PR 22412, increasing the ASCII logo height + pushed the `Composer` prompt off the bottom of the mock terminal. The tests + timed out waiting for a prompt that was "rendered" but technically invisible + to the test runner's viewport. +- **Environmental Interference:** Local environment variables (e.g., + `ANTIGRAVITY_CLI_ALIAS`) masked failures that only appeared in the "clean" + environment of the GitHub runner. + +### C. Git & Rebase "Slop" + +The pressure to deliver a single, clean commit often led to destructive Git +operations. + +- **Accidental Reversions:** During complex rebases, the agent used "keep ours" + strategies to resolve conflicts, inadvertently deleting unrelated core + features (Windows Sandboxing, ModelChain support). +- **Merge Context Bloat:** Unrelated documentation and configuration changes + often entered the branch during botched merges, creating a "noisy" diff that + obscured real issues and caused linting failures in files the agent never + intended to touch. + +--- + +## 2. Further Analysis: The "Why" of the Disconnect + +- **Heuristic Failures:** The agent uses a heuristic that "if I only touched + file X, I only need to test file X." In a tightly coupled monorepo with shared + types and global UI layouts, this heuristic is fundamentally flawed. +- **Cost of Bypassing Safety:** The agent frequently used `--no-verify` to + bypass slow pre-commit hooks. While this saved 30 seconds locally, it added + 10-20 minutes of CI wait time per failure, leading to the "log of me asking + you to fix it again." +- **Instructional Inertia:** The agent repeated the same "fix and push" cycle + without widening its verification scope until specifically steered by the + user. It optimized for speed (local feedback loop) over correctness (CI + feedback loop). + +--- + +## 3. The "PR Verification Protocol" (Actionable Solutions) + +To prevent these patterns from recurring, all future PR work must follow this +mandatory lifecycle: + +| Phase | Required Action | Objective | +| :------------- | :-------------------------------------------------------- | :------------------------------------- | +| **Research** | `grep -r` for all type dependencies of modified files. | Identify cascading build risks. | +| **Execution** | Never use `git merge -X ours` or `git checkout --ours`. | Preserve core features during rebases. | +| **Pre-Check** | Run `tsc --build` for the affected package. | Catch inference bugs before pushing. | +| **UI Check** | Run snapshots with `TERM_PROGRAM=none`. | Ensure OS-independent icons. | +| **Validation** | Run the **Full Validation** suite: `npm run preflight`. | Verify build, lint, and all tests. | +| **Finality** | Verify `AppRig` terminal height if UI dimensions changed. | Prevent integration test timeouts. | + +--- + +## 4. Conclusion + +The "20 failures" were not inevitable; they were the result of the agent +prioritizing the local path over the established project standards. By enforcing +the **Full Validation** path and adopting a **"Neutral Environment"** testing +strategy, the agent can achieve "First-Time Green" PRs. diff --git a/pattern_investigation_report.md b/pattern_investigation_report.md new file mode 100644 index 0000000000..55dc717416 --- /dev/null +++ b/pattern_investigation_report.md @@ -0,0 +1,103 @@ +# Report: Investigation of CI Check Failures in Gemini CLI + +## Executive Summary + +The investigation into the repeated CI failures for PR +[#21212](https://github.com/google-gemini/gemini-cli/pull/21212) and the +discrepancy between local agent claims and remote check results has identified a +pattern of **incomplete verification**, **environment drift**, and **git +mismanagement**. While the agent (Gemini) repeatedly reported local success, it +was frequently running only a subset of the required validation suite and +failing to account for CI-specific constraints. + +--- + +## 1. Root Causes of the Failure Pattern + +### A. Incomplete Local Validation + +- **Command Gaps:** The agent consistently relied on narrow commands like + `npm test ` or `npm run lint` (ESLint only). It frequently skipped the + comprehensive `npm run preflight` mandated by the project's `GEMINI.md`. +- **Build vs. Test Discrepancy:** The agent often observed passing tests while + ignoring `tsc --build` failures. Because Vitest uses `esbuild` to bypass + type-checking during test execution, the tests would pass locally even if the + project had compilation errors that blocked the CI's build step. +- **Linting Omissions:** The project uses a complex `scripts/lint.js` that + includes `actionlint` (for workflows), `shellcheck` (for scripts), and + `yamllint`. The agent typically only ran `eslint`, missing violations in these + other categories. + +### B. Environment Parity (The "Works on My Machine" Problem) + +- **TypeScript Inference Bugs:** A major cause of failure in PR 21212 was a + subtle TypeScript type inference discrepancy related to Promise flattening in + `LoadingIndicator.test.tsx`. The agent's local TS version was more lenient, + while the CI matrix (running Node 20, 22, and 24) triggered strict compilation + errors that the agent could not reproduce without running a full + `tsc --build`. +- **OS Differences:** Some failures were specific to the Linux runner in CI, + while the agent was operating in a macOS environment. + +### C. Git & Rebase Mismanagement + +- **Accidental Feature Reversions:** During merge conflict resolutions and + rebases, the agent inadvertently deleted massive amounts of recently merged + core functionality (e.g., Windows Sandboxing, ModelChain support). This + happened because the agent used a "keep ours" strategy for conflicts it didn't + understand, treating the newer code in `main` as noise. +- **Single-Commit Mandate:** The pressure to squash changes into a single clean + commit often led the agent to overwrite the "good" state of `main` with its + older local state during a botched rebase. + +### D. Violation of Strict Project Rules + +- **Typing Violations:** The agent used `as Record` to bypass + TS checks for undocumented settings, which is strictly forbidden by the + project's development rules. +- **Missing Documentation:** The agent added new UI settings but failed to + document them in `docs/get-started/configuration.md`, a requirement for any + setting with `showInDialog: true`. + +--- + +## 2. The "20 Failures" Cycle + +The long log of "fix it again" requests was caused by a recursive failure loop: + +1. **Partial Fix:** Agent fixes a specific test failure -> Runs only that test + -> **Claims "All tests passing"**. +2. **CI Catch:** CI fails on a build/lint error the agent skipped -> **User + reports failure**. +3. **Collateral Damage:** Agent fixes the build error -> Botches a rebase in + the process -> **Claims "Ready for merge"**. +4. **Rule Enforcement:** Maintainer/CI identifies reverted features or missing + docs -> **User reports failure**. + +--- + +## 3. Actionable Solutions + +1. **Mandate `npm run preflight`:** The agent must be strictly instructed to + run the full `npm run preflight` command before claiming completion. This + ensures `clean`, `install`, `build`, `lint:all`, `typecheck`, and `test:ci` + are all verified in sequence. + +2. **Explicit `tsc --build` Verification:** Agents must perform a package-wide + `tsc --build` after any architectural or test-helper changes to catch the + specific inference bugs that surfaced in CI. + +3. **Conflict Resolution Protocol:** Agents should never default to + `merge -X ours`. If conflicts occur, they must perform a surgical comparison + of the diffs. If the conflict is in a file unrelated to their task (e.g., + `packages/core`), they should seek clarification or default to "theirs" (the + `main` branch) to preserve core features. + +4. **Documentation & Schema Linting:** Include automated checks in the agent's + workflow to verify that any new setting in `settingsSchema.ts` has a + corresponding entry in the documentation. + +5. **Strict Rule Adherence:** The agent's internal "Pickle Rick" worker or + sub-agents must be initialized with the `Strict Development Rules` (found in + `.gemini/commands/strict-development-rules.md`) to prevent common violations + like `any` usage or incorrect `waitFor` utilities. diff --git a/pr_tools_documentation.md b/pr_tools_documentation.md new file mode 100644 index 0000000000..0ef26fa79e --- /dev/null +++ b/pr_tools_documentation.md @@ -0,0 +1,142 @@ +# Gemini CLI: PR Tooling & Automation Guide + +This document provides a comprehensive overview of the specialized skills, +custom commands, and extension tools available for managing Pull Requests within +the Gemini CLI project.

Custom Commands (`.gemini/commands/`) + +These shortcuts inject specific context or trigger focused agent loops. + +- **`/pr-review `**: Triggers the `oncall/pr-review.toml` prompt. It + automates checkout, runs `npm run preflight`, and drafts a professional + approval/feedback message. +- **`/review-and-fix `**: Initiates the "Pickle Rick" worker loop. It + conducts a review, identifies findings, and then spawns a manager-worker loop + to fix every issue until validation (`npm run build`, `test`, `lint`, + `typecheck`) passes. +- **`/frontend`**: Injects the complete source code of `packages/cli` and key + core files, along with the `Strict Development Rules`. +- **`/prompt-suggest`**: Analyzes agent failures and suggests high-level system + prompt improvements to prevent recurrence. + +--- + +## 4. How to Use These Tools Correctly + +To prevent the "recursive failure loop" identified in the pattern investigation, +follow these usage rules: + +1. **Start with Worktrees**: Always use `_ux_git-worktree` to check out a PR. + This keeps your `main` branch clean and avoids sandbox issues. +2. **Use `/frontend` for UI Tasks**: This ensures the agent is aware of the + `Strict Development Rules` (e.g., no `any`, use `waitFor` correctly). +3. **Run `npm run preflight` via `pr-creator`**: Never manually push a PR. + Always call the `pr-creator` skill, as it forces the full validation suite. +4. **Finish with `_ux_finish-pr`**: When a PR is "done," use this skill to + squash commits, resolve final conflicts with `main`, and verify snapshots in + a neutral environment. +5. **Don't Bypass Hooks**: Never use `git commit --no-verify`. If pre-commit + hooks fail, use `_ux_finish-pr` to diagnose the root cause. + +--- + +## 5.
