# Nightly MCP SDK watch (#1063).
#
# Keeping up with SDK releases — the OAuth churn especially — had been a manual
# habit rather than a mechanism, which is what #1063 was filed to fix. This
# workflow is the mechanism, and it is the third of this repo's issue-filing
# sweeps, after the monthly `dependency-refresh.yml` (#2229) and the daily
# `dependabot-alerts.yml` (#2233):
#
#   npm registry -> sweep -> issue -> Opus analysis comment -> maintainer PR -> v2/main
#
# Two jobs, and the split is load-bearing:
#
#  * `sweep` is deterministic and cheap. It compares the `@modelcontextprotocol/*`
#    packages installed on `v2/main` against the registry and files one tracking
#    issue per upstream that is behind. It runs every night and is a complete
#    no-op when nothing moved.
#  * `analyze` is the "have Opus read the SDK changes" half of #1063. It runs
#    ONLY over issues the sweep just created — never over one that already
#    existed — which is what keeps it to exactly one analysis per SDK release
#    rather than a near-identical comment every night for as long as the issue
#    stays open.
#
# ⚠️ Why this files an issue and not a PR, and why it is NOT the Copilot coding
# agent that #1063's comment sketched. Assigning `copilot-swe-agent` is possible
# here (it is in `suggestedActors`), but two things rule it out. Its run produces
# a PULL REQUEST — the artifact carrying no `Closes #N` and no board card that
# #2229/#2233/#2235 removed from this repo — and its model cannot be selected
# programmatically at all: assignment goes through `replaceActorsForAssignable`,
# which takes no model parameter, and absent an admin-configured picker the agent
# runs Sonnet. `claude-code-action` has neither problem: it is told to post a
# COMMENT and nothing else, and `--model` says exactly which model runs.
#
# ⚠️ A scheduled workflow only ever runs from the DEFAULT branch (`main`), while
# we ship from `v2/main`. So this file does nothing until a milestone merge
# carries it to `main`, and both jobs check `v2/main` out explicitly rather than
# reading the branch they were launched from — the same shape both sibling
# sweeps use.
#
# Tokens: `GITHUB_TOKEN` is sufficient for the sweep (`issues: write` to file,
# plus public registry and milestone reads). `ANTHROPIC_API_KEY` is an
# ORGANIZATION secret already available to this repo and is what `analyze` runs
# on. Board placement is deliberately not attempted by either job — that needs an
# org-project PAT no token in this org has — so a filed-but-unboarded issue is
# picked up by the next `/issue-triage` sweep, exactly as `dependency-refresh.yml`
# leaves it.

            A new ${{ matrix.target.label }} release is out, and issue #${{ matrix.target.issue }}
            in ${{ github.repository }} tracks upgrading to it. You are checked out on `v2/main`,
            the branch this repo ships from.

            Upstream: https://github.com/${{ matrix.target.repo }}
            Installed here: ${{ matrix.target.from }}
            New release: ${{ matrix.target.to }}

            Work out what actually changed upstream between those two versions, and what — if
            anything — this repository has to change to adopt it. Then post ONE comment on issue
            #${{ matrix.target.issue }} with your findings.

            How to go about it:

            1. Read the upstream release notes and changelog for every version in the range, not
               just the newest. `gh release list --repo ${{ matrix.target.repo }}` and
               `gh release view` are the fastest route; the repo's CHANGELOG is a fallback.
            2. Find how this repo actually uses the SDK. Nearly all of it is under `core/`
               (`core/mcp/` for the client and transports, `core/auth/` for OAuth), with the
               clients consuming it through the `@inspector/core` alias. `AGENTS.md` is the map.
            3. Judge impact against THIS codebase, not in the abstract. A breaking change in an
               API we never call is worth one line saying so; a quiet behavior change in one we
               depend on is the finding that matters.

            Write the comment as:

            - **Verdict** — one sentence: is this a routine bump, or does it need real work?
            - **What changed upstream** — the notable entries, with the version each landed in.
              Say plainly if the release notes are thin or missing rather than inventing detail.
            - **What it means here** — the specific files or areas that need attention, with
              paths. Say "no changes needed" if that is the honest answer.
            - **Risks and unknowns** — anything you could not determine. Do not paper over a gap.

            Hard constraints:

            - Post exactly ONE comment, on issue #${{ matrix.target.issue }}, and nothing else.
            - Do NOT open a pull request, create a branch, commit, push, or edit any file in this
              repository. Do not edit the issue body or change its labels, milestone, or state.
            - End the comment with a line noting it was generated automatically by the nightly SDK
              watch and is a starting point for review, not a verified upgrade plan.
            - If you cannot determine what changed, say exactly that in the comment. A short
              honest comment is the correct output; a confident invented one is not.
