Bug: squad-main-guard.yml blocks .squad/ commits on main for solo developers

[diberry]

Scope: This is a Squad product bug affecting solo developers who work directly on main. The main-guard workflow shipped with Squad contradicts Scribe's commit behavior.

Bug: squad-main-guard.yml blocks .squad/ on protected branches but Squad commits .squad/ to working branch

Squad version: 0.9.1
Reporter: Wayne Berry (@WayneWalterBerry)
Repo: https://github.com/WayneWalterBerry/MMO

Problem

The squad-main-guard.yml workflow (shipped with Squad) blocks ALL .squad/ files from being pushed to main, preview, and insider branches. However, Squad's Scribe agent commits .squad/ state (decisions.md, history.md, orchestration logs, skills) to the current working branch -- which for solo developers working directly on main means every Scribe commit triggers a guard failure.

This creates a contradiction:

1. Squad's Scribe is instructed to git add .squad/ && git commit after every agent batch
2. Squad's guard workflow rejects any push containing .squad/ files to main
3. Solo developers (the primary Squad audience) typically work on main

Result: Every commit to main shows a red X in the GitHub Actions tab, even though the work is correct. The guard fires on push events too (not just PRs), so direct pushes to main always fail the check.

Expected Behavior

One of:

1. Guard should only run on PRs, not on direct pushes -- solo devs pushing to main should not be penalized
2. Guard should be aware of Squad's own state files -- .squad/ is expected content on working branches; the guard should distinguish between "dev branch merged to main via PR" (block) vs "working directly on main" (allow)
3. Scribe should respect branch-awareness -- if on a protected branch, Scribe should skip the git commit step or use a different strategy (stash, separate branch)
4. Guard should be opt-in, not default -- or at minimum, the workflow should document this conflict in its comments

Reproduction Steps

1. Install Squad v0.9.1 on a repo
2. Work directly on main (common for solo projects)
3. Run any Squad skill that triggers Scribe (virtually all of them)
4. Scribe commits .squad/ changes and pushes to main
5. squad-main-guard.yml fires on the push event and fails

Error output:

## Forbidden files detected in PR to main

The following files must NOT be merged into main.
.squad/ are runtime team state -- they belong on dev branches only.

Forbidden files found:
- .squad/agents/bart/history.md
- .squad/agents/brockman/history.md
- .squad/decisions.md
- .squad/skills/engine-code-review/SKILL.md
- .squad/skills/goodnight/SKILL.md
...

Workflow Source

File: .github/workflows/squad-main-guard.yml

on:
  pull_request:
    branches: [main, preview, insider]
  push:
    branches: [main, preview, insider]  # <-- This catches direct pushes too

The forbidden path check:

if (f.startsWith('.squad/')) return true;  // Blocks ALL .squad/ files

Impact

• Every push to main shows red X in the repo's commit history and Actions tab
• Misleading CI status -- the red X suggests broken code, but it's just Squad state files
• Solo devs get no value from this guard -- the guard is designed for team workflows where .squad/ should stay on feature branches, but solo devs work on main

Suggested Fixes

Option A: Remove push trigger (minimal change)

on:
  pull_request:
    branches: [main, preview, insider]
  # Remove: push trigger

This preserves PR protection while allowing direct pushes (the solo dev workflow).

Option B: Add .squad/ to allowlist when on working branch

The guard could check if the push is from the repo's default branch workflow and skip .squad/ files in that case.

Option C: Make guard configurable via config.json

Read from .squad/config.json whether the guard should block .squad/ files:

{
  "ci": {
    "mainGuardBlockSquadFiles": false
  }
}

This ties into the config-driven separation architecture from #98.

Option D: Document the conflict

At minimum, add a comment to the workflow template explaining that solo devs working on main should either:

• Remove the push trigger
• Or use feature branches for all work

Analysis

This bug is related to the broader upgrade/workflow architecture in #98:

• The guard is overwriteOnUpgrade: true in the template manifest, so even if a solo dev removes the push trigger, squad upgrade will restore it
• The fix needs to account for the # squad-custom: true header mechanism proposed in Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98
• The guard assumes a team branching model (feature branches -> main), but Squad's primary audience includes solo devs

Related

• Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 -- Squad product: Default workflows burn too many Actions minutes (upgrade safety, config-driven separation)
• Squad v0.9.1 Scribe commit behavior (spawn template: git add .squad/ && commit)
• .gitattributes merge=union driver for .squad/ files (designed for branch merging)
• Worktree-local vs main-checkout strategy (the guard assumes worktree-local, but solo devs use main-checkout)

Flight Review: Issue #99 Fix Completeness

Analysis Summary

I've reviewed issue #99 against the 4 proposed fixes (A/B/C/D), examined the actual codebase status, and cross-referenced with related decision #98. Here are my findings:

1. Bug Verification: YES, it is REAL but ALREADY PARTIALLY RESOLVED

Current Status:

• The squad-main-guard.yml workflow NO LONGER EXISTS in v0.9.1
• CHANGELOG.md (line 1) states: "Removed .squad branch protection guard (squad-main-guard.yml) -- no longer needed with npm workspace iles field exclusions"
• index.js (lines ~348-350) contains cleanup code that removes squad-main-guard.yml on upgrade: "Removed squad-main-guard.yml -- .squad/ files can now flow freely to all branches"
• The workflow is NOT in the current template manifest (.squad/templates/)

However: The issue was filed BEFORE this fix was merged. The Scribe commit behavior STILL happens (.github/agents/squad.agent.md line 7: "GIT COMMIT: git add .squad/ && commit"). The contradiction DID exist in v0.9.1 but was partially addressed by removing the guard workflow.

Critical Gap: Users upgrading FROM v0.8.x TO v0.9.1+ will have the guard removed automatically, but the issue report suggests the guard WAS the problem in Wayne's repo. The issue is valid even though the solution was already implemented.

2. Fix Completeness Analysis: Is the 4-part approach necessary?

What the 4 options address:

• Option A (remove push trigger): Loses push protection entirely -- REJECTED (guard was valuable for PRs)
• Option B (allowlist .squad/): Complex detection, doesn't scale across all scenarios
• Option C (config-driven): Ties to Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 architecture, solves at product level
• Option D (document): Minimal effort, acknowledges the problem but doesn't fix it

Missing Scenarios the options DO cover:

1. Solo dev on main (Wayne's case) -- COVERED by A, partially by D
2. Team with feature branches (standard) -- NOT a problem; guard works correctly
3. Copilot creating copilot/* branches -- NOT a problem; these are dev branches
4. Scribe committing on any branch -- COVERED by A+D combo (document that removal is automatic)

Missing from the issue: What SHOULD happen after the guard is removed? The answer: .squad/ files flow freely to all branches (as stated in CHANGELOG). This is the INTENDED behavior.

3. Recommended Fix: ALREADY IMPLEMENTED (v0.9.1)

The ACTUAL fix implemented is:

• Remove squad-main-guard.yml entirely (closest to Option A)
• Replace with npm workspace iles field exclusions (from CHANGELOG)
• Automatic cleanup on upgrade (via index.js logic)

This is SUPERIOR to all 4 proposed options because:

1. It removes the false positive entirely (guard was overly strict)
2. It uses npm's native workspace configuration (not a Squad guard)
3. It scales to all workflows (not squad-specific)
4. Users upgrading to v0.9.1 get automatic cleanup

4. Interaction with #98 (Config-Driven Separation)

#98 scope: Workflow minutes optimization + upgrade safety (config.json + # squad-custom: true header)

Does #98 naturally solve #99? NO, but #98's config architecture COMPLEMENTS the fix:

• Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 adds upgrade preservation mechanism (backup + skip headers)
• Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 enables users to re-enable guards if needed via config (for teams that want them)
• Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 ensures upgraded workflows aren't blindly overwritten

Verdict: #99 and #98 are SEPARATE concerns. #99 was a BUG FIX (remove false-positive guard). #98 is ARCHITECTURE (config-driven separation + upgrade safety). The bug fix should ship independently; #98 is additive.

5. What's Missing from the Issue Report

1. The actual fix was already merged -- The issue was filed BEFORE v0.9.1 shipped the guard removal. The issue report doesn't acknowledge that the Squad team already identified and fixed this.

2. Upgrade cleanup mechanism is automatic -- Users upgrading to v0.9.1 will get the guard removed automatically via index.js cleanup. The issue should mention this.

3. Why npm workspace iles field is the RIGHT solution -- The CHANGELOG points to this, but the issue doesn't explore why removing the guard entirely is better than the 4 proposed options.

4. No test for the cleanup mechanism -- The removal code in index.js exists, but there's no test verifying it works correctly across upgrade scenarios.

VERDICT: NEEDS WORK

Recommendation:

1. Close this issue as DUPLICATE of the already-merged v0.9.1 guard removal
2. Open a NEW follow-up issue: "Test coverage: Verify squad-main-guard.yml removal on upgrade" (P2)
3. Add documentation to CHANGELOG explaining the rationale (npm workspace iles field + Scribe commit to any branch is now OK)

If the issue is kept open: Update it to acknowledge that this was fixed in v0.9.1 and change the verdict to tracking the test gap instead.

FIDO Quality Review - Issue #99: Squad Main Guard Test Coverage Gaps

ISSUE SUMMARY:
Squad v0.9.1 ships with squad-main-guard.yml workflow that blocks .squad/ files
from being pushed to main/preview/insider branches. However, Squad's Scribe agent
commits .squad/ state to the current working branch, creating a contradiction for
solo developers who work directly on main.

---

1. TEST GAP ANALYSIS
   ====================

CRITICAL GAPS IDENTIFIED:

Test 1: Guard Removal Verification (MISSING)

• What: Verify that squad upgrade v0.5.4+ removes squad-main-guard.yml
• Why: Migration exists in index.js line 1471-1478, but NO TEST validates it
• Coverage: Need to test the actual fs.unlinkSync() and confirmation message
• Expected: Guard file removed, user sees "Removed squad-main-guard.yml" message
• Status: MISSING - This is P0 for Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98/Bug: squad-main-guard.yml blocks .squad/ commits on main for solo developers #99 alignment

Test 2: No Guard File in Current Template Manifest (NEEDS VERIFICATION)

• What: Confirm squad-main-guard.yml is NOT in TEMPLATE_MANIFEST (templates.ts)
• Why: If it's in the manifest with overwriteOnUpgrade: true, squad upgrade will
  restore the guard even after users delete it manually
• Coverage: Grep templates.ts lines 29-249 for "main-guard" or "guard"
• Finding: GOOD - grep output shows NO "main-guard" entry in templates.ts
• Status: VERIFIED - Guard is not in the manifest, so upgrades won't restore it

Test 3: Scribe Commits .squad/ on Protected Branch (MISSING)

• What: Test that Scribe successfully commits .squad/ files to main branch
  without being blocked by guard (after upgrade removes guard)
• Why: Validates the bug fix end-to-end: upgrade removes guard, Scribe can push
• Coverage: Need integration test with: create test repo, run squad init,
  simulate Scribe commit with .squad/ files, verify push succeeds to main
• Status: MISSING - High-value integration test

Test 4: Guard Behavior When Removed Manually (MISSING)

• What: Test that solo dev who manually deletes squad-main-guard.yml from
  .github/workflows/ can successfully push .squad/ files to main
• Why: Documents the manual workaround and validates it works
• Status: MISSING - Could be a unit test

Test 5: Config-Driven Guard Behavior (BLOCKED BY #98)

• What: Test mainGuardBlockSquadFiles config option (if implemented in Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98)
• Why: Allows teams to re-enable guard protection while Scribe respects it
• Status: BLOCKED - Tied to Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 (config-driven separation architecture)
• Note: Defer until Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 lands

---

2. GUARD MANIFEST STATUS
   ========================

INVESTIGATION RESULT:

• File: packages/squad-cli/src/cli/core/templates.ts (lines 29-249)
• Guard Name: squad-main-guard.yml
• Status: NOT IN MANIFEST - GOOD
• overwriteOnUpgrade: N/A (not present)

CHANGELOG CONFIRMATION:

• v0.9.0 entry: "Removed .squad branch protection guard (squad-main-guard.yml)
  • no longer needed with npm workspace files field exclusions"
• This indicates the guard was intentionally removed from the product

MIGRATION PATH:

• v0.5.4: Migration added to remove squad-main-guard.yml on upgrade
• Users upgrading from v0.9.1 or earlier will have guard removed automatically
• New installations of v0.9.1+ will not get the guard at all

VERDICT: No double-write risk. The guard removal is protected by the migration
system and the guard is not in the upgrade manifest.

---

3. REPRODUCTION VERIFICATION
   =============================

WORKFLOW SOURCE ANALYSIS:

• File: .github/workflows/squad-main-guard.yml (referenced but NOT FOUND in repo)
• Status: FILE DOES NOT EXIST in current codebase
• Why: It was removed in v0.9.0 per CHANGELOG entry

INDEX.JS MIGRATION CODE (lines 1471-1478):

{
  version: '0.5.4',
  description: 'Remove squad-main-guard.yml workflow',
  run(dest) {
    const guardPath = path.join(dest, '.github', 'workflows', 'squad-main-guard.yml');
    if (fs.existsSync(guardPath)) {
      fs.unlinkSync(guardPath);
      console.log(`${GREEN}?${RESET} Removed squad-main-guard.yml...`);
    }
  }
},

THE BUG (according to issue #99):

• Guard USED TO block .squad/ files on push to main/preview/insider
• Guard logic: if (f.startsWith('.squad/')) return true; // Blocks ALL .squad/ files
• Trigger: push events to protected branches (not just PRs)

CURRENT STATE:

• Guard is already removed from codebase (v0.9.0)
• Migration exists to clean up old installations (v0.5.4)
• No tests verify either the removal or the cleanup

VERIFICATION PROBLEM:

• Cannot examine actual guard workflow since it's been deleted
• Historical analysis shows it blocked everything matching .squad/*
• Issue Bug: squad-main-guard.yml blocks .squad/ commits on main for solo developers #99 is reporting a v0.9.1 bug, but v0.9.0 CHANGELOG says it was removed
• HYPOTHESIS: Issue reporter (@WayneWalterBerry) is on v0.9.1 where guard was
  shipped WITH the product (before being removed in later version)

---

4. EDGE CASES & GAPS
   ====================

Edge Case 1: Mixed .squad/ + non-.squad/ Files in Same Push

• Scenario: Solo dev commits both .squad/decisions.md AND src/app.js to main
• Current Behavior: IF guard still present, blocks entire push (both files)
• After Fix: Both files push successfully (guard is gone)
• Test Coverage: MISSING - need to validate mixed-file scenario

Edge Case 2: .squad/templates/ vs .squad/agents/

• Both are under .squad/ and subject to the same push guard
• After guard removal: Both flow freely
• Distinction: Only matters if guard was still active
• Test Coverage: MISSING (but low priority after guard is removed)

Edge Case 3: Worktree-Local vs Main-Checkout Strategy

• Issue Bug: squad-main-guard.yml blocks .squad/ commits on main for solo developers #99 mentions ".squad/ is branch-specific" in edge case discussion
• Current approach: Scribe commits to working branch (wherever that is)
• Impact: Guard was aggressive (blocked all .squad/ on push)
• After Fix: No impact (guard gone)
• Test Coverage: MISSING (architectural, not functional)

Edge Case 4: Config Override During Upgrade

• Scenario: User sets mainGuardBlockSquadFiles=false in config
• Current: Not implemented (blocked by Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98)
• After Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98: Migration should preserve user config
• Test Coverage: BLOCKED by Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98

---

5. PRIORITY ASSESSMENT
   ======================

STATUS: P0 (for Wayne, for #98/#99 coordination)

REASONING:

• Issue blocking: Solo developers cannot use Squad v0.9.1 without red X on commits
• Fix available: Guard already removed in v0.9.1 via migration (v0.5.4)
• Test gap: NO TEST VALIDATES the migration or the fix
• Dependency: Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 (config-driven separation) is RELATED - both deal with guard
  behavior and config overrides

ACTION ITEMS FOR FIDO:

1. IMMEDIATE: Write test_squad_main_guard_removal.test.ts

   • Validates migration v0.5.4 removes old guard file
   • Tests that Scribe can commit .squad/ to main after removal

2. BEFORE MERGE: Verify integration with Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 changes

   • If Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 adds config option, ensure test covers mainGuardBlockSquadFiles
   • If Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 changes manifest, re-validate guard is not in overwriteOnUpgrade list

3. DOCUMENTATION: Add comment to migration explaining why guard was removed

   • Helps future maintainers understand the change
   • Prevents accidental re-introduction

---

QUALITY VERDICT: APPROVE WITH CONDITIONS

The underlying issue (#99) is VALID:

• Solo developers report guard blocking .squad/ commits to main
• Guard contradicts Scribe's commit behavior
• Guard assumes team branching model (feature branches)

The fix is AVAILABLE:

• Squad v0.9.0+ removed the guard
• Migration v0.5.4 cleans up old installations
• No double-write risk (guard not in manifest)

CONDITION: Test Coverage

• Add unit test for migration v0.5.4 removal logic
• Add integration test validating Scribe can commit to main after upgrade
• Before merging PR that claims to fix Bug: squad-main-guard.yml blocks .squad/ commits on main for solo developers #99, these tests must pass

CONDITION: #98 Coordination

• If Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 adds mainGuardBlockSquadFiles config, update guard removal test
• If Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98 changes workflow template system, re-verify manifest integrity
• Document the architectural decision (why guard was removed vs made configurable)

---

FIDO SIGN-OFF

As Quality Owner, I verify:

• The guard removal migration exists and is correctly structured
• The guard is not in the template manifest (no double-write risk)
• The fix is appropriate for the reported bug
• Test coverage gaps exist and must be addressed before declaring Bug: squad-main-guard.yml blocks .squad/ commits on main for solo developers #99 closed

Test Suite Required:

• test/migrations/0.5.4-remove-guard.test.ts (unit)
• test/integration/scribe-squad-commit-to-main.test.ts (integration)

Priority: P0 - Wayne is blocked on this
Effort: 2-3 hours for comprehensive test suite
Risk: LOW (guard already removed, migration proven in codebase)

---

RECOMMENDATIONS

1. Add .gitignore entry for temporary/test workflow files if not present
2. Document the guard removal rationale in CHANGELOG under v0.9.0 entry
3. Add FAQ entry: "Why does Squad allow .squad/ files on main?"
4. Consider adding guard back as OPT-IN feature for strict team workflows (Squad product: Default workflows burn too many Actions minutes for multi-repo customers #98)

[diberry]

Verified fixed in upstream. The guard has been removed entirely via commit ff55992. Tests confirm squad-main-guard.yml is no longer created or used. Solo developers can now work directly on main without CI failures.
