feat(T22): replace Anthropic SDK with OpenAI-compatible provider - #8
Merged
Conversation
Swap every agent off @langchain/anthropic onto any OpenAI-compatible endpoint, defaulting to OpenRouter with the free nemotron model. - add src/agent/llm.ts — single createLlm(temperature) factory, provider selected by LLM_BASE_URL (OpenRouter default, NVIDIA NIM supported) - drop the six duplicated ChatAnthropic instances across the agents - remove @langchain/anthropic; bump @langchain/core for the openai peer - swap ANTHROPIC_API_KEY for LLM_API_KEY in the three workflows - disable the mock user seeding cron (workflow_dispatch retained) Trending digest improvements: - align repo count at 5-8 across prompt, tool schema and user message; the schema description was silently overriding the prompt's "1-3" - bound summaries to 140 chars in code, not just in the prompt - restrict tags to a closed vocabulary so hashtags stay searchable - escape url and tags before rendering into the HTML message Fix total star counts always rendering as 0: GitHub puts an svg icon between the stargazers anchor and the number, so the regex never matched. Verified against the live page (0 matches before, 18 after). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CFr2cPw9xvDvStaya9sDW8
The v2 action verifies `fallow-lsp` and `fallow-mcp` binaries, but from fallow 3.x the platform packages ship a single multicall `fallow` binary. Since the action installs the latest CLI by default, every run failed with `binary-missing`. v3's verifier expects only `fallow`.

Summary
Moves every agent off the Anthropic SDK onto any OpenAI-compatible endpoint, defaulting to OpenRouter with
nvidia/nemotron-3-ultra-550b-a55b:free. Follows the pattern already used in thedamoproject'sKpiSummaryAgent.@langchain/anthropicis removed entirely — no references remain insrc/, the workflows,.env.example, or the README.Changes
Provider swap
src/agent/llm.ts— a singlecreateLlm(temperature)factory. Provider is chosen byLLM_BASE_URL; OpenRouter and the nemotron free model are the built-in defaults, so only the API key is required. NVIDIA NIM works by overridingLLM_BASE_URL/LLM_MODEL.new ChatAnthropic(...)instances across the agents.LLM_API_KEYis unset rather than failing deep inside an agent call.@langchain/corebumped to satisfy@langchain/openai's peer dependency.Mock users — seeding cron disabled,
workflow_dispatchretained. Code untouched.Trending digest prompt
.describe()said 5–8 while the prompt said 1–3; the schema was silently winning.urlandtagsare now escaped before going into the HTML message.Bug fix — star counts were always 0
The digest had been sending
⭐ 0for every repo. GitHub places a star<svg>between the stargazers anchor and the number, and the regex expected digits immediately after the opening tag. Against the live page: 0 matches before, 18 after.Testing
Ran
pnpm newsend to end against the free model. Verified from the database:stars = 0pnpm run tscTelegram delivery confirmed on each run.
Deploy notes
One secret change under Settings → Secrets and variables → Actions:
ANTHROPIC_API_KEYLLM_API_KEY(OpenRouter key)All other secrets are unchanged.
Known issue, not addressed here
The free model occasionally skips the tool call.
curateReposcannot distinguish that from "the model curated nothing" —toolOutputreturns'',parseJsonfalls back to{}, and the job exits quietly. On Actions that is a green check with no digest sent. Hit once during testing; an immediate re-run with identical input succeeded. Worth a retry-on-missing-tool-call in a follow-up.🤖 Generated with Claude Code
