feat: Add undo tool and JSON/YAML validation for edit/write tools (ARM-20) by agent-vera[bot] · Pull Request #2 · stepandel/vera

agent-vera · 2026-03-14T19:37:49Z

Summary

Implements both features from ARM-20:

1. Undo Tool

New src/tools/undo.ts: Standalone undo tool that restores a file to its pre-edit state
One-level deep undo — stores the most recent version per file path in a shared Map<string, string>
Wired into builtin-tools.ts alongside read/edit/write so all tools share the same previousVersions map
edit.ts and write.ts snapshot file contents into previousVersions before every write
After undo, history is cleared (prevents undo-of-undo) and fileHashes is updated for stale detection
Returns a diff showing what was restored

2. JSON/YAML Validation

New src/tools/file-validation.ts: Post-write validator for JSON (JSON.parse) and YAML (yaml.parse)
Called automatically after every successful edit or write
Non-blocking: appends a ⚠️ Warning to the success message if the file doesn't parse — the write still succeeds
Returns null for non-JSON/YAML files (no validation attempted)

Tests (25 new tests, all passing)

undo.test.ts: restore, history clearing, hash updates, diff output (5 tests)
file-validation.test.ts: JSON/YAML valid/invalid, non-validatable file types (12 tests)
edit.test.ts: previousVersions snapshots on edit/replace, validation warnings for JSON/YAML (8 tests)

Files Changed

New: undo.ts, file-validation.ts, undo.test.ts, file-validation.test.ts, edit.test.ts
Modified: edit.ts, write.ts, builtin-tools.ts

Closes ARM-20

Extract shared runAgentTask helper to eliminate ~40 lines of duplicated session logic. Change agent/delegate tool schemas from single `task` to `tasks` array, running them concurrently via Promise.allSettled with p-limit(3). Move p-limit to production dependencies. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Spawn a fresh validator agent after the main agent finishes to review modified files, run build/tests, and fix issues. Enabled via VALIDATION_ENABLED=true env var. Integrated into headless, Linear, and GitHub handlers. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Add .pi/agents/validator.md with system prompt, model, and tool config - Rewrite validation.ts to load the agent definition and delegate to runAgentTask instead of manually spawning sessions - Filter validator out of delegation tools (like main) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Replace getModifiedFiles() with getWorkingTreeDiff() which returns combined staged + unstaged diffs plus untracked file names. The validator now receives the actual diff in a code block, giving it full context of what changed without needing to read every file. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Parse PASS/FAIL status from validator report. On failure, feed the validator's report back to the main agent session (which is still alive) so it can address the issues with full conversation context. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Add `guidelines` frontmatter field to AgentDefinition, surfaced as `promptGuidelines` on the tool so the model knows WHEN to use each agent - Fix HTML comments before frontmatter delimiters that silently broke parseFrontmatter — descriptions, model, tools, and thinking config were all being ignored (falling back to defaults) - Add clear usage guidelines to architect and scout agent definitions - Strengthen delegation guidance in main agent system prompt Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Scout and architect were missing web_search and web_fetch, limiting them to codebase-only analysis. Also add find/ls to main agent's tool docs and mention web tools in scout/architect body text. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The search tool handles both content search and file discovery (glob, type filters), making find and ls redundant. Also update the default fallback tool list in agent-session-runner. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…M-20) Undo: - New undo.ts tool: restores a file to its pre-edit state (one-level deep) - Shared previousVersions Map wired through builtin-tools.ts - edit.ts and write.ts snapshot file contents before every write - Undo clears its history after use; updates fileHashes for stale detection Validation: - New file-validation.ts: validates JSON (JSON.parse) and YAML (yaml.parse) - edit.ts and write.ts call validateFileContent() after every write - Non-blocking: appends a warning to success message if parse fails - No validation for non-JSON/YAML files (returns null) Tests: - undo.test.ts: restore, history clearing, hash updates, diff output - file-validation.test.ts: JSON/YAML valid/invalid, non-validatable files - edit.test.ts: previousVersions snapshots, validation warnings

@agent-vera please fix merge conflicts

agent-vera · 2026-03-16T05:09:53Z

Merge conflicts resolved and pushed. Here's a summary of what was done:

Merge Conflict Resolution Summary

Resolved 10 conflicted files from merging master into the PR branch. The conflicts arose because master merged several PRs after this branch diverged: .pi → .anton directory rename, search tool removal, parallel task output formatting changes, GitHub progress tracking, and agent-session-runner type improvements.

Resolution decisions per file:

File	Resolution
`.anton/agents/*.md` (3 files)	Take master — directory rename + content updates
`.anton/agents/validator.md`	Move from `.pi/` to `.anton/`, remove `search` tool reference
`src/tools/builtin-tools.ts`	Keep PR's `BuiltinToolMaps`/undo/`previousVersions`; drop `search`/`find`/`ls` (search removed on master, find/ls don't exist in package)
`src/tools/agent-session-runner.ts`	Take master (typed imports, `onEvent`, `getModelDynamic`); fix `createBuiltinTool` call to use `BuiltinToolMaps` instead of plain `Map`
`src/tools/agent-tools.ts`	Take master's output format; keep PR's validator filter
`src/tools/delegate.ts`	Take master (cleaner output format)
`src/github/handler.ts`	Merge both — PR's validation pass + master's `activitySummary`
`src/headless.ts`	Keep PR's validation pass

Additional fix (not in conflict markers):

src/tools/cron/executor.ts: Updated createBuiltinTool call to use BuiltinToolMaps — this caller was outside conflict markers but would have broken at runtime after the signature change.

⚠️ No Node.js runtime was available in the environment to run the build or tests. Please verify the build passes in CI.

Resolve merge conflicts: - src/agents/validator.md: moved to new src/agents/ location (renamed from .anton/agents/) - src/github/handler.ts: kept validation import, removed duplicate session import - src/headless.ts: kept both new master imports and branch validation import - src/linear/handler.ts: took master's refactored handler (validation was in old handler code, now needs runtime.ts) - src/tools/agent-session-runner.ts: kept BuiltinToolMaps + added langsmith import from master - src/tools/agent-tools.ts: deleted (removed in master, branch changes were trivial) - src/tools/builtin-tools.ts: kept BuiltinToolMaps with previousVersions for undo support - src/tools/cron/executor.ts: kept BuiltinToolMaps + master's registry-based custom tool resolution - src/tools/edit.ts: kept previousVersions.set() calls for undo snapshots - src/tools/write.ts: used node: prefixed imports from master + kept file-validation import - src/tools/workflow/engine-builtins.ts: updated to use BuiltinToolMaps - Fixed test type errors (TextContent | ImageContent union)

agent-vera · 2026-03-25T19:06:52Z

All merge conflicts resolved and pushed. Here's what I did:

10 conflicting files resolved:

File	Resolution
`src/agents/validator.md`	Moved to `src/agents/` (master renamed `.anton/agents/` → `src/agents/`)
`src/github/handler.ts`	Kept validation import, removed duplicate session import
`src/headless.ts`	Kept both master's new imports and branch's validation import
`src/linear/handler.ts`	Took master's refactored handler (old validation code was for pre-refactor handler)
`src/tools/agent-session-runner.ts`	Kept `BuiltinToolMaps` + added langsmith import from master
`src/tools/agent-tools.ts`	Deleted (removed in master, branch changes were trivial)
`src/tools/builtin-tools.ts`	Kept `BuiltinToolMaps` with `previousVersions` for undo support
`src/tools/cron/executor.ts`	Kept `BuiltinToolMaps` + master's registry-based custom tool resolution
`src/tools/edit.ts`	Kept `previousVersions.set()` calls for undo snapshots
`src/tools/write.ts`	Used `node:` prefixed imports from master + kept file-validation import

Additional fixes:

Updated src/tools/workflow/engine-builtins.ts to use BuiltinToolMaps (was passing plain Map)
Fixed test type errors in edit.test.ts and undo.test.ts (TextContent | ImageContent union)
Fixed validateWork call in handler.ts that referenced undefined prompt variable

Verification: TypeScript compiles clean (tsc --noEmit) and all 25 new tests pass.

Pushed. The CI failure was all Biome lint/formatting issues in the branch's new and modified files:

node: protocol: file-validation.ts and undo.ts used "path" and "fs/promises" instead of "node:path" and "node:fs/promises"
Import ordering: Several files had unsorted imports (biome's organizeImports rule)
Unused variables: store in undo.test.ts, result/result2 in file-validation.test.ts
Unused imports: edit.test.ts had imports that were no longer used
Formatting: Various files had multi-line expressions that biome wanted collapsed, plus a trailing blank line in linear/handler.ts

All fixed with biome check --write --unsafe plus a manual fix for the destructured store variables. TypeScript compiles clean and all 25 tests still pass.
