AI Template Sync — Skill

Sync the smooth-ai-stockanalysis agentic scaffold into a landing repo (UPSERT — safe merge, not destructive replace).

TL;DR

0. If the template isn't checked out locally (running as a skill via web / hosted agent), clone it to a temp dir first.
1. Ask which AI tools to configure.
2. Optionally copy .NET solutioning.
3. Pre-flight: if .agents/rules isn't a symlink to .github/instructions, ask whether to move the rules.
4. Detect conflicts; ask for overwrite scope.
5. Copy files per tool selection.

---

Phase 0 — Acquire Template (remote / web runs)

Run this ONLY when the template repo is not already checked out at the current location — i.e. the skill is invoked as a landing-repo skill (web / hosted agent / a repo that doesn't contain the template). If you are already inside a checkout of the template repo, skip Phase 0 and let --template default to the current git toplevel.

The sync scripts copy from the template tree (.agents/, .github/instructions/, copilot-instructions.md, optional src//tests/). None of that lives under the skill folder, so pulling just the skill is not enough. The script self-acquires the whole template: pass --template-url <git-url> (-TemplateUrl on Windows) instead of --template and it shallow-clones to a temp dir and cleans up on exit. Add --template-ref <tag|sha> to pin for reproducibility.

bash sync.sh --template-url https://github.com/generic-automation-and-it/smooth-ai-stockanalysis \
  --landing "$PWD" --tools <claude,codex,copilot> --overwrite <global|none> [--dotnet]

Caveats (one line): the runner needs Bash + git + network; a private template needs gh-auth or a token embedded in the clone URL.

The interactive phases below (1–3) still apply — gather intent and run the pre-flight before invoking the cloned script. Phase 0 only solves getting the files, not the decisions.

---

Phase 1 — Gather Intent (ask, then stop for answers)

Ask the user all questions in one message:

1. Which AI tools to configure? (comma-separate any combo)
   a) Claude Code   b) OpenAI Codex   c) GitHub Copilot

2. Copy .NET solutioning? (only asked if the landing repo has no *.slnx / *.sln)
   Includes: smooth-ai-stockanalysis.slnx · Directory.Build.props · Directory.Packages.props
             NuGet.Config · src/ · tests/
   [y/n]

3. Overwrite mode for agentic files?
   A) Global overwrite — replace every agentic file without further prompting
   B) Selective — show me a conflict table first; I'll pick what to overwrite
   (Dotnet files are never overwritten regardless of choice.)

Wait for user answers before proceeding.

---

Phase 2 — Rules-Layout Pre-flight (ALWAYS run, even in Global mode)

The template's contract is: .github/instructions/ is the real directory that holds the rule files, and .agents/rules is a symlink pointing to it. A landing repo may not follow this — it may keep .agents/rules as a real directory of its own rules, or symlinked somewhere else.

This matters because Section D of the sync (scripts/sync.sh) unconditionally runs rm -rf .agents/rules and re-points the symlink — in both overwrite modes. If .agents/rules is a real directory, that step destroys the repo's own rules. So this check runs regardless of the Phase 1 overwrite choice, and only when copilot is among the selected tools (Section D runs only then).

Inspect the landing repo:

readlink "<LANDING_REPO>/.agents/rules"   # prints ../.github/instructions in a conforming repo; empty/non-zero exit if it's a real dir

If .agents/rules exists but is not a symlink resolving to .github/instructions (i.e. it is a real directory, or a symlink pointing elsewhere), stop and ask before running the sync:

Your repo's `.agents/rules` is NOT a symlink to `.github/instructions`
(it is <a real directory | a symlink to X>).

The template keeps rule files in `.github/instructions/`, with `.agents/rules`
symlinked to it. The sync would otherwise delete `.agents/rules` and re-point it,
losing your existing rules.

Move your existing rules into `.github/instructions/` and re-point
`.agents/rules` at it as part of this update? [y/n]

• y → before invoking the script, move the existing rule files into .github/instructions/ (merge, don't clobber the template rules), then let Section D re-point the .agents/rules symlink. The repo's own rules are preserved.
• n → do not run with copilot in --tools (Section D would still rm -rf .agents/rules). Either drop copilot from the tools list, or sync the other tools first and handle Copilot's rules dir manually. Leave the existing layout untouched.

If .agents/rules already symlinks to .github/instructions, or neither path exists, take no action and proceed.

---

Phase 3 — Conflict Detection (Selective mode only)

Skip if user chose Global overwrite.

Agentic file inventory

Category	Files / paths
Base scaffold	.agents/** (all files recursively) · AGENTS.md
Claude Code	.claude (symlink) · CLAUDE.md (symlink) · GEMINI.md (symlink)
Codex	.codex (symlink)
Copilot	.github/copilot-instructions.md · .github/instructions (real directory — holds the rule files; .agents/rules symlinks to it)
Setup scripts	.agents/setup/scripts/agents-setup.sh · .agents/setup/scripts/agents-setup.ps1 · .agents/setup/scripts/agents-terminals.sh · .agents/setup/scripts/agents-terminals.ps1

Check each file/path against the landing repo. Build a conflict table for every item that already exists:

#	Name	Purpose	Action
1	.agents/hooks/load-agents-context.sh	PostToolUse hook — emits AGENTS.md context	skip
…	…	…	…

Print the table, then ask:

Enter IDs to overwrite (e.g. "1 3 5"), "all", or "none":

Collect the response before moving to Phase 4.

Phase 4 — Execute Sync

The mechanical copy/symlink work (Sections A–E) is performed by scripts/sync.sh (scripts/sync.ps1 on Windows). You decide the flags from the Phase 1–3 answers; the script executes them. It is idempotent and supports two overwrite modes — global (clobber) and none (additive, never clobber).

Never touch dotnet files (.slnx, .sln, Directory.*.props, NuGet.Config, src/, tests/) during agentic sync, even if the user requests it here. The script's --dotnet path only ever adds them when no solution exists, and never overwrites.

.agents/skills/ai-template-sync/scripts/sync.sh \
  --landing <LANDING_REPO> \
  --tools claude,codex,copilot \
  [--dotnet] \
  --overwrite global|none

.agents/skills/ai-template-sync/scripts/sync.ps1 `
  -Landing <LANDING_REPO> `
  -Tools claude,codex,copilot `
  [-Dotnet] `
  -Overwrite global|none

Flag	Maps to	Notes
--tools / -Tools	Phase 1 Q1	Comma-separated subset of claude,codex,copilot. Drives Sections B/C/D.
--dotnet / -Dotnet	Phase 1 Q2	Section E. Skipped automatically if a .slnx/.sln already exists.
--overwrite global	Phase 1 Q3 = A	Clobber every agentic file.
--overwrite none	Phase 1 Q3 = B (after selection)	Additive only — never clobber existing files.
--template / -Template	(auto)	Template repo root; defaults to the current git toplevel.
--template-url / -TemplateUrl	Phase 0	Git URL of the template; the script shallow-clones it to a temp dir and cleans up on exit. Mutually exclusive with --template. Use for remote / web runs.
--template-ref / -TemplateRef	(optional)	Tag/branch/SHA to pin the --template-url clone to. Use for reproducible rule installs.
--rules-only / -RulesOnly	(optional)	Sync ONLY the rule system — see Rules-Only Distribution below.

What each section does (now inside the script):

• A — .agents/ base tree: rsync (global = overwrite, none = --ignore-existing); never deletes landing-only files.
• B — Claude Code: .claude→.agents, CLAUDE.md/GEMINI.md→AGENTS.md symlinks + git config core.symlinks true.
• C — Codex: .codex→.agents symlink.
• D — Copilot: copies the real .github/instructions/ dir, re-points .agents/rules symlink at it, copies copilot-instructions.md.
• E — .NET: copies Directory.*.props, NuGet.Config, *.slnx, src/, tests/ only when absent. Rename SmoothAiStockAnalysis.* → <ActualProjectName> afterwards (the script prints this reminder; the rename itself is the agent's job).

Selective overwrite (Phase 1 Q3 = B): the script handles global and none only. For true per-file selection, copy the user-approved files manually first, then run the script with --overwrite none so it adds the remainder without clobbering anything.

---

Rules-Only Distribution (--rules-only)

Distribute or update the rule system as a package — .github/instructions/ (the real rules dir, shared by Claude/Cursor/Copilot via symlinks) plus the .agents/rules symlink — without touching skills, hooks, setup scripts, or dotnet files:

.agents/skills/ai-template-sync/scripts/sync.sh \
  --template-url https://github.com/generic-automation-and-it/smooth-ai-stockanalysis \
  --template-ref v1.2.0 \
  --landing "$PWD" \
  --rules-only \
  --overwrite global|none

Semantics:

• --overwrite global updates same-named rule files to the pinned version; none only adds missing ones. Landing-only rule files are never deleted in either mode (UPSERT) — a consumer's own rules survive updates.
• --tools / --dotnet are ignored; Phases 1 and 3 don't apply. The Phase 2 rules-layout pre-flight is built into the script here: it refuses (exit 65) if .agents/rules is a real directory.
• Re-run with a newer --template-ref to upgrade — this is the supported way to consume this repo's rules from other repositories.

Phase 5 — Post-Sync Checklist

After all copies/symlinks are done, report:

✅ Sync complete. Next steps for the landing repo:

□ Run the setup script once:
    bash .agents/setup/scripts/agents-setup.sh   # Mac/Linux
    pwsh .agents/setup/scripts/agents-setup.ps1  # Windows

□ Update AGENTS.md — replace template placeholder content with real project context.

□ [Claude Code] Verify `.claude/` symlink resolves:  ls -la .claude

□ [Codex] Verify `.codex/` symlink resolves:  ls -la .codex

□ [Copilot] Verify `.github/instructions/` is a real dir and `.agents/rules` symlinks to it:  ls -la .github/instructions .agents/rules

□ [.NET] Rename SmoothAiStockAnalysis.* → <ActualProjectName> everywhere (if .NET was copied).

□ Commit the agentic scaffold with:  git add -A && git commit -m "chore: add smooth-devex agentic scaffold"

Guardrails

• Never overwrite dotnet files (.slnx, .sln, Directory.*.props, NuGet.Config, src/, tests/) during agentic sync.
• Never delete landing-repo files absent from the template.
• Always confirm before executing file writes/copies; show the plan first.
• In Selective mode, skip any file not explicitly approved by the user.
• Symlinks require git config core.symlinks true; remind the user if the repo was cloned with symlinks off.
