Spiderly Upgrade

End-to-end version upgrade for apps consuming Spiderly via the NuGet packages (Spiderly.Shared, Spiderly.Security, Spiderly.Infrastructure, Spiderly.SourceGenerators) and the spiderly npm package. (Spiderly.CLI is a dotnet tool, not a project reference — out of scope.)

Invocation forms:

• /spiderly-upgrade <version> — explicit target (e.g. 21.2.0)
• /spiderly-upgrade latest — fetch latest stable from NuGet
• /spiderly-upgrade — same as latest

Spiderly has no backward-compatibility commitment — every release can break public API. This skill closes that gap by reading what changed on GitHub, scanning the user's app for what actually affects them, asking once, then applying everything with build-verification and self-healing retries.

Step 1 — Pre-flight

Follow Spiderly's fail-loudly convention: every refused-to-start condition exits non-zero with an actionable message. Cache the parsed csproj and package.json contents from this step — Step 6 reuses them.

1. Locate the app. Glob **/*.csproj and **/package.json from CWD (skip node_modules, bin, obj). Identify the Backend (csproj with Spiderly.* PackageReferences) and Frontend (package.json with "spiderly" dep). If neither is found, exit:

> Not a Spiderly app: no Spiderly.* PackageReference or spiderly npm dep found from this directory.

1. Reject local-dev consumers. If any csproj has a <ProjectReference Include="...\spiderly\..."> pointing at a sibling Spiderly checkout, exit:

> This skill is for NuGet/npm consumers. You're using local ProjectReferences to a sibling spiderly/ directory — upgrade by git pull in that directory instead.

1. Require clean git state. Run git status --porcelain. If non-empty, exit:

> Working tree must be clean before upgrading. Commit or stash your changes first — the upgrade will make many edits, and a clean tree is your git restore . safety net.

1. Detect current version. Versions live in one of two places — check for Central Package Management first:

• CPM (`Directory.Packages.props` exists next to or above the csprojs): versions are <PackageVersion Include="Spiderly.X" Version="..." /> there, and the csprojs carry versionless <PackageReference Include="Spiderly.X" />. Reading Version= off the csprojs finds nothing — don't conclude "not a Spiderly app".
• Classic: Version= on each csproj's PackageReference.

Read whichever applies, plus the "spiderly" value in Frontend/package.json. They should agree. If they drift, list the values and ask the user which to treat as "current". Record which layout you found — Step 6 bumps the same place.

1. Multi-solution monorepo. If multiple Backend dirs (each with their own Spiderly refs) exist, ask the user which one to upgrade. One app per invocation.

Step 2 — Resolve target version

• If arg is latest or omitted: WebFetch https://api.nuget.org/v3-flatcontainer/spiderly.shared/index.json, parse the versions array, pick the highest stable (no - suffix), confirm with the user.
• Otherwise validate the arg as X.Y.Z (or X.Y.Z-preview.N if the user is explicitly opting into a preview — warn that preview release notes are usually thin).
• Reject downgrades: if target < current, exit Downgrades are not supported. To downgrade, edit the Spiderly.* versions (Directory.Packages.props under CPM, otherwise the csproj PackageReference Version= attributes) and the "spiderly" npm dep manually, then run dotnet restore and npm install.
• Reject no-op: if target == current, exit Already on {version}.

Step 3 — Fetch what changed

Fire these two WebFetch calls in parallel (same message, two tool calls):

1. Diff between tags. https://api.github.com/repos/filiptrivan/spiderly/compare/v{current}...v{target} (three-dot syntax). Response has files[] with filename and patch. Filter client-side to the user-facing paths below — GitHub's compare endpoint has no path-filter parameter. If truncated: true, warn the user the diff was capped and proceed with what was returned.

1. All release notes in one call. https://api.github.com/repos/filiptrivan/spiderly/releases?per_page=100. Returns every release. Filter in-memory to tags v{X.Y.Z} strictly above current and ≤ target. Concatenate body fields in ascending version order. (One call, not N — Spiderly's total release count fits in one page.)

On 403 rate-limited: ask the user to export GH_TOKEN (no scopes needed) and retry.

User-facing file paths (filter the compare response client-side)

Include — changes here affect consumers:

• Spiderly.Shared/**/*.cs — public attributes, contracts, builders
• Spiderly.Security/**/*.cs — auth interfaces, attributes
• Spiderly.Infrastructure/**/*.cs — DI extensions, base services
• Spiderly.SourceGenerators/**/*.cs — generator output shape changes (may break consumer overrides)
• Spiderly.Shared/Helpers/NetAndAngularFilesGenerator.cs — init template; drift here implies existing apps may need mirroring edits (new service registration, new file in scaffold)
• Angular/projects/spiderly/src/lib/**/*.ts
• Angular/projects/spiderly/src/public-api.ts

Exclude — *.Tests/**, tests/**, Spiderly.CLI/** (consumers don't reference CLI internals — flag CLI flag/command changes only via release notes), Angular/node_modules/**, Angular/dist/**, .github/**, .claude-plugin/**, claude-plugins/**, *.csproj, package.json, *.md.

Step 4 — Impact scan and plan

Read the combined release notes + filtered diff in a single pass. Identify changes that likely affect a consumer:

• New / renamed / removed public types, methods, attributes in Spiderly.Shared, Spiderly.Security, Spiderly.Infrastructure
• Changes in source-generator output shape (consumers may have overrides that no longer compile)
• Changes in the init template — signals what NEW apps look like; existing apps may need to mirror (e.g. a new services.AddTransient<X>())
• Changes in the Angular library's public surface (public-api.ts exports, component/service contracts)
• CLI command/flag changes (if the user has CI scripts invoking spiderly)

For each candidate change:

1. Describe in one line what changed.
2. Use Grep over the user's codebase to find real usages. Read context, don't just match symbol names blindly.
3. If no real usages exist, drop the item from the plan.

Plan format:

Spiderly upgrade: 19.5.0 → 21.2.0
 
Code edits (N items affect you):
  1. <change> — <N> usages in <files>
  2. ...
 
Manual steps after upgrade:
  - <step the agent can't do for you>
 
Version bumps: Spiderly.*  19.5.0 → 21.2.0  (Directory.Packages.props | 4 csproj + Frontend/package.json[ + .claude/settings.json legacy-plugin removal])
 
After approval: apply → bump → migrate guidance + config → restore + install (parallel) → build → agent-sync. Up to 2 build-fix retries on failure.

Step 5 — Single approval gate

Present the plan and ask the user explicitly. Don't proceed without a clear yes.

Step 6 — Apply

In this order. A failure at any step is a hard stop until the recovery procedure in Step 7.

1. Code edits. Apply each plan item via Edit. Read each target file first.
2. Version bumps. Bump the layout detected in Step 1.4:

• CPM: rewrite each <PackageVersion Include="Spiderly.X" Version="OLD" /> in Directory.Packages.props. The csprojs need no edit — that is the point of CPM, and adding a Version= there is an error (NU1008).
• Classic: iterate the csproj list cached in Step 1 and rewrite every <PackageReference Include="Spiderly.X" Version="OLD" />.

Then rewrite "spiderly": "OLD" in Frontend/package.json. Don't re-glob.

If the app commits `packages.lock.json` files (RestorePackagesWithLockFile), the restore in item 5 updates them — but only for the current OS's resolution graph. Apps whose CI restores in --locked-mode on linux must regenerate the locks under the linux SDK image, or a macOS-only regeneration ships a lock that CI rejects. Add it to the manual steps:

``bash docker run --rm -v "$PWD:/src" -v <cache-volume>:/root/.nuget/packages -w /src \ mcr.microsoft.com/dotnet/sdk:<version> dotnet restore <Solution>.sln --force ``

1. Migrate agent guidance off the legacy plugin. Spiderly's AI-agent guidance now ships inside the spiderly npm package (projected by spiderly agent-sync in item 7 below), replacing the old spiderly@spiderly Claude Code plugin. If .claude/settings.json contains extraKnownMarketplaces.spiderly and/or enabledPlugins."spiderly@spiderly", remove just those keys (leave any other settings intact; delete the file only if it becomes an empty {}). No settings file or no spiderly entries → skip.
2. Migrate `spiderly.json` → `.spiderly/config.json`. Recent Spiderly moved the generator/api config out of a root spiderly.json into .spiderly/config.json. If the app has a spiderly.json registered via <AdditionalFiles Include="spiderly.json" />, git mv it to .spiderly/config.json and rewrite that csproj line to <AdditionalFiles Include=".spiderly/config.json" />. No spiderly.json → skip.
3. Restore packages in parallel. Same message, two Bash calls: dotnet restore in Backend and npm install in Frontend. They share no locks. If either fails, surface the actual error and exit.
4. `dotnet build` from the Backend dir. On failure, go to Step 7.
5. Sync agent guidance. Run spiderly agent-sync from the app root. It reads the freshly-installed Frontend/node_modules/spiderly/agent bundle and reconciles AGENTS.md (doc index + @AGENTS.md in CLAUDE.md) and .claude/skills/spiderly-* (junctions, pruning any renamed/removed skill). Idempotent; non-fatal if it warns the bundle is missing (an older package predating the bundle).

Step 7 — Build-failure recovery (max 2 retries)

Loop up to 2 times — stop on first green build:

1. Scan output for the first `SPIDERLY`-prefixed diagnostic (these are the root cause; downstream CS0246 errors about missing *DTO types are noise). Fall back to the first CS error only if no SPIDERLY diagnostic exists.
2. Read the offending file. Apply the most likely fix using the error message + the diff context from Step 3.
3. Re-run dotnet build.

After 2 failed attempts, stop:

Upgrade halted after 2 build-fix attempts.
 
Build error still present:
  <paste the diagnostic>
 
Attempted fixes:
  1. <what>
  2. <what>
 
The in-progress upgrade is in your working tree.
  - To roll back: git restore .
  - To continue manually: fix the error, run `dotnet build`, then commit.

Step 8 — Done

Print summary:

• Versions bumped (from → to)
• Files edited (count + list)
• Manual steps remaining (re-print verbatim from the plan)

Do not auto-commit. The user reviews the diff and commits themselves.

Refresh AI-agent guidance

After the new spiderly package is installed, project the version-matched guidance:

spiderly agent-sync

This is idempotent and reconciling: it rewrites the static AGENTS.md docs pointer, ensures CLAUDE.md imports it (@AGENTS.md), and adds/refreshes/prunes .claude/skills/spiderly-* junctions so renamed or removed skills self-heal. Re-running it is always safe.

Rules

• Never auto-revert. Leave the in-progress state in the working tree so the user can see what was attempted; they roll back with git restore .
• Never silently drop a candidate breaking change. If the diff shows one but you can't determine impact, include it in the plan as "verify manually".
