Run a TDD parser-fix workflow for perl-parser-core or related parser crates. Use when a parser bug has a concrete failing construct and needs tests, a minimal fix, and verification.

Parser Fix

Fix a parser bug with a failing test first. Bug: $ARGUMENTS

Workflow

Find the relevant parser code under crates/perl-parser-core/src/engine/parser/
Add failing tests first in the right parser test file
Implement the smallest fix that makes the new tests pass
Verify the parser crates cleanly
Return a concise receipt for the handoff or PR

Root-Cause Search

Start with the file surface most likely to own the construct:

variables.rs
statements.rs
expressions/postfix.rs
expressions/precedence.rs
declarations.rs

Understand why the construct fails before editing.

Test-First Rule

Add tests before the fix. Prefer crate-local parser tests that parse a Perl snippet and assert success or the intended AST shape.

Verification

cargo fmt --all
cargo clippy -p perl-parser-core --lib
cargo test -p perl-parser-core
cargo test -p perl-parser

Keep the fix narrow. If the failure turns out to be primarily lexer or corpus work, route it into the right worker instead of silently widening the slice.

coding-standards

EffortlessMetrics/perl-lsp

Load perl-lsp coding standards for code-writing or code-review work in this repo. Use when implementing, fixing, reviewing, or validating code.

merge-queue

EffortlessMetrics/perl-lsp

Merge approved PRs in safe batches — checks CI, fixes policy failures, handles conflicts, ratchets corpus after parser merges.

plan-fix

EffortlessMetrics/perl-lsp

Turn a discovery into a builder-ready handoff packet. Use when a scout or coordinator has identified a concrete slice and needs exact scope, verification, and routing rather than code changes.

2026-03-2023

scout-then-build

EffortlessMetrics/perl-lsp

Research-first workflow that scouts exact scope before launching a constrained builder. Use when a feature or fix is too unconstrained for a direct builder — converts ~50% success into ~90% by eliminating implicit decisions.

swarm-priorities

EffortlessMetrics/perl-lsp

Load roadmap weighting for scouts and coordinators so slices are ranked by actual repo priorities instead of convenience.

2026-03-2023

swarm-protocol

EffortlessMetrics/perl-lsp

Load shared swarm behavioral rules for coordinators and workers. Use for task routing, receipts, direct messaging, dedup, worktree boundaries, and lifecycle discipline.
