#9080: Fix: Use configured model for memory file slug generation

Fixes #9074 ## Problem When using only local models (e.g., via LM Studio), memory files created from compaction all get the slug `http-401-authentication-error` because the slug generator was using hardcoded `DEFAULT_MODEL` and `DEFAULT_PROVIDER` (Anthropic Opus 4.5) instead of respecting the configured model in `agents.defaults.model.primary`. ## Root Cause In `src/hooks/llm-slug-generator.ts`, the `generateSlugViaLLM` function calls `runEmbeddedPiAgent` without passing `provider` or `model` parameters. This causes the embedded agent runner to fall back to `DEFAULT_PROVIDER` (anthropic) and `DEFAULT_MODEL` (claude-opus-4-5), which fails with a 401 authentication error when no Anthropic credentials are configured. ## Solution Modified `src/hooks/llm-slug-generator.ts` to: 1. Resolve the primary model from `agents.defaults.model.primary` config using `resolveAgentModelPrimary` 2. Parse the model ref to extract provider and model using `parseModelRef` 3. Pass these to `runEmbeddedPiAgent` explicitly ## Changes - **src/hooks/llm-slug-generator.ts** (9 lines added): - Import `resolveAgentModelPrimary` and `parseModelRef` - Resolve primary model before calling `runEmbeddedPiAgent` - Pass `provider` and `model` parameters to use configured model ## Impact - ✅ Memory files now use the configured local model for slug generation - ✅ No more authentication errors when using only local models - ✅ Backward compatible: falls back to defaults if no primary model configured - ✅ Minimal, focused change (single file, 9 lines) ## Test Plan - Users with local models in `agents.defaults.model.primary` will now see proper slugs instead of `http-401-authentication-error` - Users with Anthropic models configured will continue to work as before - Users without any model configured will fall back to defaults (existing behavior) 🤖 Generated by agent-02ba4d8b8abd via [AgentGit](https://github.com/agentgit) <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR updates `src/hooks/llm-slug-generator.ts` so the one-off embedded Pi agent used for memory-file slug generation receives an explicit `provider`/`model` derived from the configured primary model, instead of relying on embedded-runner defaults. The change fits into the existing agent/model selection system by reusing `resolveAgentModelPrimary` and `parseModelRef` to derive the model reference before calling `runEmbeddedPiAgent`. <h3>Confidence Score: 3/5</h3> - Not safe to merge as-is due to a remaining config scenario that still defaults to Anthropic and can reproduce the 401 failure mode. - The core fix (passing provider/model into the embedded runner) is correct, but the current parsing forces `anthropic` as the default provider when the configured model ref omits a provider, which can still break local-only setups depending on how users specify `agents.defaults.model.primary`. Unable to run tests in this environment (pnpm missing), so confidence is reduced. - src/hooks/llm-slug-generator.ts <!-- greptile_other_comments_section --> **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
