Agent Improvement Proposal

Pattern Detected

Type: coordination_improvement
Affected Agent: ca-uat-tester
Evidence: 13 out of 20 open PRs are conflicting docs/showcase PRs

Detailed Evidence

As of 2026-04-08, the open PR list shows 13 documentation PRs created by the UAT tester, most of which have mergeable: false (merge conflicts):

PR	Title	Mergeable
#4226	docs: add comprehensive showcase documentation for 8 new CLI feature areas	❌ false
#4225	docs: add session management workflows showcase example	❌ false
#4224	docs: add showcase example for repo indexing workflows	✅ true
#4223	docs: add showcase example for REPL and actor run commands	❌ false
#4221	docs: add showcase example for audit log and security commands	❌ false
#4220	docs: add actor context management showcase	✅ true
#4217	docs: add actor management workflow showcase example	❌ false
#4216	docs: add showcase example for project init and context management	❌ false
#4214	docs: add showcase example for action and plan management lifecycle	❌ false
#4213	docs: add showcase example for resource and skill management	✅ true
#4212	docs: add showcase example for tool and validation management	❌ false
#4211	docs: add showcase example for CLI version/info/diagnostics basics	❌ false
#4210	docs: add showcase example for config and automation profiles	❌ false
#4209	docs: add showcase example for output format flags	❌ false

All 14 PRs were created on 2026-04-07 within a few hours. 10 out of 14 have merge conflicts.

Root Cause Analysis:

The create_documentation_pr function in ca-uat-tester.md (lines 636-676) creates individual branches and PRs for each documentation example. Each worker:

Clones from master (same base commit)
Creates a new branch
Writes a new docs file
Updates examples.json index (line 654: update_examples_json(example))
Commits and pushes
Creates a PR

When multiple UAT workers run in parallel (the pool supervisor dispatches N workers simultaneously), they all branch from the same master commit and all modify the shared examples.json index file. After the first PR merges, all remaining PRs have merge conflicts on examples.json.

This creates a cascade where:

Only 1 PR can merge cleanly
The remaining 13 PRs all need manual conflict resolution
The PR review pipeline gets clogged with unmergeable PRs
Reviewer time is wasted reviewing PRs that can't be merged

Proposed Change

Add a sequential documentation PR strategy to the UAT tester's documentation generation workflow. Two options (recommend Option A):

Option A: Batch documentation into a single PR per pool cycle

Instead of creating individual PRs per feature area, the pool supervisor should:

Collect all documentation examples from completed workers in a cycle
Create ONE branch with ALL documentation files from that cycle
Update examples.json once with all new entries
Create a single PR with all documentation changes

This eliminates inter-PR conflicts entirely since there's only one PR per batch.

Option B: Sequential PR creation with rebase

If individual PRs are preferred (for easier review), modify create_documentation_pr to:

Before creating a branch, fetch the latest master (not the stale clone)
After creating the PR, check if any other docs PRs are open
If so, rebase the new branch on top of the latest docs branch
Add a note in the PR description about dependency ordering

Expected Impact

Eliminate docs PR merge conflicts: No more 10+ conflicting PRs clogging the review pipeline
Faster review throughput: Reviewers can merge docs PRs without manual conflict resolution
Reduced PR count: Fewer PRs means less load on the continuous-pr-reviewer pool
Cleaner git history: No merge conflict resolution commits

Risk Assessment

Low risk for Option A: Batching is a straightforward change that reduces complexity
Medium risk for Option B: Rebase logic adds complexity and could fail if the base changes during PR creation
Potential downside of Option A: Larger PRs are harder to review, but documentation PRs are typically low-risk and can be reviewed as a batch
No impact on bug filing: This only affects the documentation generation path, not the core testing functionality

This is a proposal from the agent evolver. A human must approve this issue before the change will be implemented. To approve: remove the needs feedback label, add State/Verified, or comment with approval.
