Major upgrade to the agent's self-validation, safety, and project integrity
capabilities through five iterations of system prompt enhancements:
Workflow & Quality Mandates:
1. Incremental Validation: Mandates building, linting, and testing after
every significant file change to maintain a "green" state.
2. Mandatory Reproduction: Requires creating a failing test case to confirm
a bug before fixing, and explicitly verifying the failure (Negative Verification).
3. Test Persistence & Locality: Requires integrating repro cases into the
permanent test suite, preferably by amending existing related test files.
4. Script Discovery: Mandates identifying project-specific validation
commands from configuration files (package.json, Makefile, etc.).
5. Self-Review: Mandates running `git diff` after every edit, using
`--name-only` for large changes to preserve context window tokens.
6. Fast-Path Validation: Prioritizes lightweight checks (e.g., `tsc --noEmit`)
for frequent feedback, reserving heavy builds for final verification.
7. Output Verification: Requires checking command output (not just exit codes)
to prevent false-positives from empty test runs or hidden warnings.
Semantic Integrity & Dependency Safety:
8. Global Usage Discovery: Mandates searching the entire workspace for all
usages (via `grep_search`) before modifying exported symbols or APIs.
9. Dependency Integrity: Requires verifying that new imports are explicitly
declared in the project's dependency manifest (e.g., package.json).
10. Configuration Sync: Mandates updating build/environment configs
(tsconfig, Dockerfile, etc.) to support new file types or entry points.
11. Documentation Sync: Requires searching for and updating documentation
references when public APIs or CLI interfaces change.
12. Anti-Silencing Mandate: Prohibits using `any`, `@ts-ignore`, or lint
suppressions to resolve validation errors.
Diagnostics, Safety & Runtime Verification:
13. Error Grounding: Mandates reading full error logs and stack traces upon
failure. Includes Smart Log Navigation to prioritize the tail of large files.
14. Scope Isolation: Instructs the agent to focus only on errors introduced
by its changes and ignore unrelated legacy technical debt.
15. Destructive Safety: Mandates a `git status` check before deleting files
or modifying critical project configurations.
16. Non-Blocking Smoke Tests: Requires briefly running applications to
verify boot stability, using background/timeout strategies for servers.
Includes 15 new behavioral evaluations verifying these mandates and updated
snapshots in packages/core/src/core/prompts.test.ts.
