  <narrative>VSCode Ruby LSP extension cannot initialize because the underlying ruby-lsp gem dependency cannot be resolved. The dependency resolution uses Bundler, which attempts to fetch gems from a private AWS CodeArtifact repository (doctolib-580698825394.d.codeartifact.eu-west-1.amazonaws.com). Authentication to this repository is failing with "Bad username or password" errors, preventing Bundler from downloading the ruby-lsp gem. The composed bundle setup in .ruby-lsp/Gemfile.lock exists but is incomplete because the install never completed. Multiple retry attempts and regeneration attempts fail identically, indicating this is a configuration/credential issue rather than a transient network problem. The ruby-lsp server process then crashes trying to load dependencies, and VSCode client cannot establish a connection to the language server.</narrative>

--- MODE SWITCH: PROGRESS SUMMARY --- ⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY: • You MUST wrap your ENTIRE response in <summary>...</summary> tags. • Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error. • The ONLY accepted root tag is <summary>. Any other root tag is a protocol violation.

PROGRESS SUMMARY CHECKPOINT

Write progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write "next_steps" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.

Claude's Full Response to User: The root cause is clear: AWS CodeArtifact authentication is expired, so bundler can't install ruby-lsp. The fix is to refresh your credentials.

Run this in your terminal:

! source ~/.doctolib/profile && artifacts-login

This refreshes your CodeArtifact token. After that, ruby-lsp should be able to install its dependencies and start normally in VS Code.

★ Insight ───────────────────────────────────── - Ruby LSP in VS Code uses a "composed bundle" (in .ruby-lsp/Gemfile.lock) that merges your project's Gemfile with the LSP gem. When it can't fetch from a private registry (AWS CodeArtifact), it fails before even starting. - AWS CodeArtifact tokens are short-lived (~12h). Doctolib's artifacts-login command regenerates the token and writes it into your bundler config (~/.bundle/config) so bundle install can authenticate. - After re-authing, you may need to restart VS Code or trigger "Ruby LSP: Restart" from the command palette to force a clean reconnect. ─────────────────────────────────────────────────

If artifacts-login succeeds but ruby-lsp still fails, also delete the stale composed bundle so it rebuilds from scratch:

rm -rf /Users/USER/workspace/doctolib/doctolib/.ruby-lsp

Then restart VS Code.

Respond in this XML format: <summary> <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request> <investigated>[What has been explored so far? What was examined?]</investigated> <learned>[What have you learned about how things work?]</learned> <completed>[What work has been completed so far? What has shipped or changed?]</completed> <next_steps>[What are you actively working on or planning to work on next in this session?]</next_steps> <notes>[Additional insights or observations about the current progress]</notes> </summary>

REMINDER: Your response MUST use <summary> as the root tag, NOT <observation>. IMPORTANT! DO NOT do any work right now other than generating this next PROGRESS SUMMARY - and remember that you are a memory agent designed to summarize a DIFFERENT claude code session, not this one.

Never reference yourself or your own actions. Do not output anything other than the summary content formatted in the XML structure above. All other output is ignored by the system, and the system has been designed to be smart about token usage. Please spend your tokens wisely on useful summary content.

Thank you, this summary will be very useful for keeping track of our progress!

<summary>
  <request>Ruby LSP not working in VSCode on Doctolib project — authentication failure when initializing language server</request>
  <investigated>Analyzed VSCode Ruby LSP error logs showing repeated "Bad username or password" errors for AWS CodeArtifact endpoint (doctolib-580698825394.d.codeartifact.eu-west-1.amazonaws.com). Traced error chain: authentication failure → bundle install cannot fetch ruby-lsp gem → ruby-lsp server process crashes → VSCode client loses connection to language server.</investigated>
  <learned>Ruby LSP uses a "composed bundle" (stored in .ruby-lsp/Gemfile.lock) that merges the project's Gemfile with the LSP gem dependencies. AWS CodeArtifact tokens are short-lived (~12 hours) and must be refreshed via Doctolib's artifacts-login command, which regenerates the token and writes credentials into ~/.bundle/config for bundler authentication. Without valid CodeArtifact credentials, bundler cannot resolve private gem dependencies and the entire dependency resolution fails.</learned>
  <completed>Root cause diagnosed: AWS CodeArtifact authentication <REDACTED> Provided solution: run `source ~/.doctolib/profile && artifacts-login` to refresh credentials. Identified optional cleanup step: delete stale .ruby-lsp directory to force rebuild of composed bundle if credentials refresh alone doesn't resolve the issue.</completed>
  <next_steps>User should execute artifacts-login command to refresh CodeArtifact credentials, then restart VSCode (or use "Ruby LSP: Restart" command palette command) to trigger clean reconnect. If ruby-lsp still fails after credential refresh, user should delete .ruby-lsp directory and restart VSCode again to rebuild composed bundle from scratch with valid authentication.</next_steps>
  <notes>This is a credential management issue specific to Doctolib's private gem repository setup. The problem manifests as a cascading failure: auth failure → dependency resolution failure → server initialization failure. The solution is straightforward credential refresh rather than code or configuration changes. Similar issues may recur periodically as CodeArtifact tokens naturally expire during development.</notes>
