Tom Boucher 792b166ce6 fix: improve LSP diagnostics when no servers detected (#1082) (#1086)
* docs: add Node LTS pinning guide for macOS Homebrew users

New doc (docs/node-lts-macos.md) explains how to pin Node 24 LTS
via Homebrew to avoid running on odd-numbered development releases.
Covers brew install/link/pin, version managers as alternatives,
and verification steps.

Added notice banner in README linking to the guide.

* fix: improve LSP diagnostics when no servers detected (#1082)

When lsp status returns 'No language servers configured', the output
now includes diagnostics:
- Which project markers were detected (e.g. package.json found)
- Which server commands are missing (e.g. typescript-language-server)
- Install instructions

Also added LSP troubleshooting section to docs/troubleshooting.md
with common install commands per language.

Troubleshooting

/gsd doctor

The built-in diagnostic tool validates .gsd/ integrity:

/gsd doctor

It checks:

  • File structure and naming conventions
  • Roadmap ↔ slice ↔ task referential integrity
  • Completion state consistency
  • Git worktree health (worktree and branch modes only — skipped in none mode)
  • Stale lock files and orphaned runtime records

Common Issues

Auto mode loops on the same unit

Symptoms: The same unit (e.g., research-slice or plan-slice) dispatches repeatedly until hitting the dispatch limit.

Causes:

  • Stale cache after a crash — the in-memory file listing doesn't reflect new artifacts
  • The LLM didn't produce the expected artifact file

Fix: Run /gsd doctor to repair state, then resume with /gsd auto. If the issue persists, check that the expected artifact file exists on disk.

Auto mode stops with "Loop detected"

Cause: A unit failed to produce its expected artifact twice in a row.

Fix: Check the task plan for clarity. If the plan is ambiguous, refine it manually, then /gsd auto to resume.

Wrong files in worktree

Symptoms: Planning artifacts or code appear in the wrong directory.

Cause: The LLM wrote to the main repo instead of the worktree.

Fix: This was fixed in v2.14+. If you're on an older version, update. The dispatch prompt now includes explicit working directory instructions.

npm install -g gsd-pi fails

Common causes:

  • Missing workspace packages — fixed in v2.10.4+
  • postinstall hangs on Linux (Playwright --with-deps triggering sudo) — fixed in v2.3.6+
  • Node.js version too old — requires ≥ 20.6.0

Provider errors during auto mode

Symptoms: Auto mode pauses with a provider error (rate limit, server error, auth failure).

How GSD handles it (v2.26):

Error type Auto-resume? Delay
Rate limit (429, "too many requests") Yes retry-after header or 60s
Server error (500, 502, 503, "overloaded") Yes 30s
Auth/billing ("unauthorized", "invalid key") No Manual resume

For transient errors, GSD pauses briefly and resumes automatically. For permanent errors, configure fallback models:

models:
  execution:
    model: claude-sonnet-4-6
    fallbacks:
      - openrouter/minimax/minimax-m2.5

Headless mode: gsd headless auto auto-restarts the entire process on crash (default 3 attempts with exponential backoff). Combined with provider error auto-resume, this enables true overnight unattended execution.

Budget ceiling reached

Symptoms: Auto mode pauses with "Budget ceiling reached."

Fix: Increase budget_ceiling in preferences, or switch to budget token profile to reduce per-unit cost, then resume with /gsd auto.

Stale lock file

Symptoms: Auto mode won't start, says another session is running.

Fix: If no other session is actually running, delete .gsd/auto.lock manually. GSD includes stale lock detection (checks if the PID is still alive), but edge cases exist.

Git merge conflicts

Symptoms: Worktree merge fails on .gsd/ files.

Fix: GSD auto-resolves conflicts on .gsd/ runtime files. For content conflicts in code files, the LLM is given an opportunity to resolve them via a fix-merge session. If that fails, manual resolution is needed.

Recovery Procedures

Reset auto mode state

rm .gsd/auto.lock
rm .gsd/completed-units.json

Then /gsd auto to restart from current disk state.

Reset routing history

If adaptive model routing is producing bad results, clear the routing history:

rm .gsd/routing-history.json

Full state rebuild

/gsd doctor

Doctor rebuilds STATE.md from plan and roadmap files on disk and fixes detected inconsistencies.

Getting Help

  • GitHub Issues: github.com/gsd-build/GSD-2/issues
  • Dashboard: Ctrl+Alt+G or /gsd status for real-time diagnostics
  • Forensics: /gsd forensics for structured post-mortem analysis of auto-mode failures
  • Session logs: .gsd/activity/ contains JSONL session dumps for crash forensics

LSP (Language Server Protocol)

"LSP isn't available in this workspace"

GSD auto-detects language servers based on project files (e.g. package.json → TypeScript, Cargo.toml → Rust, go.mod → Go). If no servers are detected, the agent skips LSP features.

Check status:

lsp status

This shows which servers are active and, if none are found, diagnoses why — including which project markers were detected but which server commands are missing.

Common fixes:

Project type Install command
TypeScript/JavaScript npm install -g typescript-language-server typescript
Python pip install pyright or pip install python-lsp-server
Rust rustup component add rust-analyzer
Go go install golang.org/x/tools/gopls@latest

After installing, run lsp reload to restart detection without restarting GSD.
