The dotnet-port-fixes-nightly workflow exceeded its 2K AIC budget (used 2002 AIC) because the port-candidate-selector sub-agent ran at full gpt-5.5 cost while fetching upstream git history and querying porting issues inline — the most expensive phases.

Changes

DataOps pre-steps (dotnet-port-fixes-nightly.md, dotnet-port-api-nightly.md)

  • Added a steps: block that runs before the agent, fetching upstream commits and recent porting issues as compact files under /tmp/gh-aw/data/ at zero AI-token cost
  • Agents read /tmp/gh-aw/data/upstream-commits.jsonl (60 compact commit entries) and /tmp/gh-aw/data/porting-issues.json instead of calling git log or issue-list tools inline

Sub-agent model downgrade

  • port-candidate-selector: model: automodel: large (resolves to sonnet/gpt-5-pro)
  • auto was resolving to gpt-5.5 (same as parent); candidate selection doesn't need frontier cost

GitHub tools: gh-proxy mode

  • github: toolsets: [context, repos, issues, pull_requests]github: mode: gh-proxy
  • Eliminates Docker MCP server startup and strips verbose GitHub tool definitions from ambient context
  • Added gh:* to bash allow-list for any remaining inline queries

Prompt updates

  • Main agent and sub-agent prompts updated to reference pre-fetched data files directly and skip redundant fetches
  • Applied identically to dotnet-port-api-nightly.md (same structure, same risk)

Both .lock.yml files recompiled with gh aw compile.

- Add DataOps pre-steps to pre-fetch upstream commits (compact JSONL)
  and recent porting issues (JSON) before the agent runs, replacing
  expensive on-demand tool calls with zero-token shell work
- Change port-candidate-selector sub-agent model from auto (resolved to
  gpt-5.5) to large (sonnet/gpt-5-pro), significantly cheaper for the
  candidate selection task
- Switch github tools to gh-proxy mode, eliminating Docker MCP server
  startup overhead and extra tool definitions from context
- Update main and sub-agent prompts to use pre-fetched data files
- Add gh:* to bash allow-list for gh-proxy mode
- Apply identical optimizations to dotnet-port-api-nightly.md
- Recompile both lock files with gh aw compile

@copilot The recompile in this PR reverted the pinned action versions in both .lock.yml files back to actions/checkout@v6.0.3, but main pins v7.0.0 (Dependabot bump #337), and the github/gh-aw-actions/setup pin also regressed vs main's v0.81.6 (#386). Please restore them to match main.

@copilot The recompile in this PR reverted the pinned action versions in both .lock.yml files back to actions/checkout@v6.0.3, but main pins v7.0.0 (Dependabot bump #337), and the github/gh-aw-actions...

Done in fix: restore pinned action versions to match main (v7.0.0, v0.82.0). Both .lock.yml files now use actions/checkout@9c091bb # v7.0.0 and github/gh-aw-actions/setup@2ad2a516 # v0.82.0, matching the base. I also restored the daily_ai_credits_exceeded output variable names and CLI/compiler version markers that had regressed along with the action versions during the old-compiler recompile.
