Sync from template repo

Update this project's Claude Code configuration from the local Claude template repo. The template's location is auto-detected per developer — Johan's macOS box has it at /Users/jool/repos/Claude, David's Linux box has it at /home/david/repos/Claude, etc. Do not hardcode either.

Resolve TEMPLATE once at the start of every sync session using this probe (in bash, runnable on macOS / Linux / Windows Git Bash):

# Auto-detect the template repo location. Stop at the first directory
# that contains CLAUDE.md AND .claude/skills/sync-template/SKILL.md
# (the two files that together unambiguously identify this template).
for CAND in "$HOME/repos/Claude" "$HOME/Projects/Claude" "$HOME/Code/Claude" "$HOME/code/Claude" "$HOME/src/Claude" "$HOME/dev/Claude" "/Users/jool/repos/Claude"; do
  if [ -f "$CAND/CLAUDE.md" ] && [ -f "$CAND/.claude/skills/sync-template/SKILL.md" ]; then
    TEMPLATE="$CAND"
    break
  fi
done

if [ -z "${TEMPLATE:-}" ]; then
  echo "[ERROR] Could not locate the Claude template repo on this machine." >&2
  echo "        Clone it: git clone https://github.com/johanolofsson72/Claude.git \$HOME/repos/Claude" >&2
  echo "        Or set TEMPLATE manually before re-running this sync." >&2
  exit 1
fi
echo "[OK] Template at: $TEMPLATE"

Throughout this skill, every reference to the template path uses $TEMPLATE, never a hardcoded absolute path. If you are reading this skill as instructions to execute, resolve $TEMPLATE first with the probe above, then substitute it everywhere the skill mentions the template repo location.

The hardcoded /Users/jool/repos/Claude references that remain elsewhere in this document are example paths showing where the file would be on Johan's machine — they are NOT meant to be used literally. Translate them to $TEMPLATE/... when you execute.

• scripts/continuous-execution-hook.sh
• scripts/stop-validation-hook.sh

• scripts/feature-pipeline-detect.sh
• scripts/spec-register-guard-hook.sh
• scripts/spec-register-orientation-hook.sh
• scripts/spec-md-coverage-reminder-hook.sh (deterministic replacement for the legacy type:"prompt" spec-completeness hook; never blocks, suppresses reminder on carved-out test slices)
• scripts/local-llm-call.sh (telemetry funnel + auto-detect)
• scripts/local-llm-detect.sh
• scripts/local-llm-stats.sh (per-hook ROI reporter)
• scripts/sync-local-llm-hooks.py (deterministic settings.json wiring + scripts/ mirror — invoked in step 3.1a)
• scripts/verify-local-llm-hooks.sh (cross-check used by step 3.1a)
• scripts/sync-core-hooks.py (deterministic settings.json wiring for the core script hooks — pipeline/spec-register/execution/tech-stack; script-presence gated — invoked in step 3.1a-core)
• scripts/sync-graphify-wiring.py (deterministic settings.json wiring + scripts/ mirror for the Graphify integration — invoked in step 3.1b)
• scripts/graphify-bootstrap.sh (cross-platform Graphify self-installer — handles macOS brew, Linux apt/dnf/pacman/zypper, Windows Git Bash via scoop/winget/choco; idempotent; eligibility-gates by source-file count — invoked in step 3.1c)
• scripts/graphify-fire-hook.sh (PostToolUse Bash hook — logs every graphify query|path|explain|update invocation to .claude/graphify-fire.log with response bytes + graph node/edge counts)
• scripts/graphify-stats.sh (per-project Graphify ROI reporter — --all flag aggregates across ~/repos/* and ~/Projects/*)

Note: scripts/local-llm-*-hook.sh files are NOT hand-globbed here. Step 3.1 invokes sync-local-llm-hooks.py, which atomically mirrors both the wiring AND the hook script files on disk (copying new ones, deleting orphans, verifying no wired hook is missing its script). Hand-globbing this set used to be a prose instruction here and proved unreliable — the LLM short-circuited the glob and produced settings.json entries referencing scripts that did not exist on disk, generating "No such file or directory" errors on every Edit/Bash. The deterministic helper closed that gap.

2. Compare and merge

For each file:

1. If the file does not exist in the target project, copy it from the template
2. If the file exists, compare and identify differences
3. Preserve any project-specific customizations (marked with # PROJECT-SPECIFIC comments)
4. Update generic template content to match the latest version
5. Report what was changed

3. Settings.json merge rules

For .claude/settings.json:

Step 3.1a — local-LLM hooks (deterministic, run the helper script):

Once scripts/sync-local-llm-hooks.py has been copied from the template to the project (in step 1), invoke it from the project root:

python3 scripts/sync-local-llm-hooks.py "$TEMPLATE/.claude/settings.json"

The script does TWO things atomically:

1. Wiring — removes every bash scripts/local-llm-*-hook.sh entry from the project's hooks block and replaces them with the template's exact set. Non-local-LLM hook entries are preserved verbatim.
2. Scripts on disk — copies every scripts/local-llm-*-hook.sh from the template into the project, and deletes any in the project that the template no longer ships. Template is the source of truth.

Finally it verifies that every wired hook has its script on disk and exits non-zero (with the list of broken refs) if anything is off. If step 3.1a exits non-zero, do NOT continue — investigate the message and rerun the script.

The script is idempotent and prints what it changed; capture that output for the report in step 6.

Do NOT try to merge local-LLM hook entries by hand and do NOT hand-glob scripts/local-llm-*-hook.sh. Both prose approaches proved unreliable (the LLM hedged on "REPLACE" wiring and short-circuited the script-copy glob, leaving 17 ghost references in one project). The script removes the ambiguity from both ends.

Step 3.1a-core — core hooks (deterministic, run the helper script):

The pipeline reminders, spec-register guard/orientation, pipeline state guard, spec-md-coverage, continuous-execution/stop-validation backstops, and the tech-stack hooks (tla, allium, sqlite, ui-design, test-coverage) are the core script-backed hooks. They used to be merged by prose ("UNION of hooks"), which is exactly what left projects missing the pipeline/register enforcement and forced a second /project-update. They are now deterministic. Once scripts/sync-core-hooks.py has been copied from the template (step 1), invoke it from the project root:

python3 scripts/sync-core-hooks.py "$TEMPLATE/.claude/settings.json"

It strips every template core hook from the project and reinstalls the template's current set — but only the hooks whose every referenced script already exists in the project. Script-presence is the tech-stack gate: a project that pruned tla-hook.sh never gets the tla hook back; one that kept it does. permissions and project-specific hooks are never touched. Idempotent (byte-stable on re-run). It exits non-zero with a list if any wired core hook is missing its script — if so, do NOT continue; investigate and rerun. Capture stdout for the report; the skipped lines record which tech-stack hooks the project deliberately lacks.

Do NOT hand-merge core hooks. Prose "UNION of hooks" is the exact failure this step replaces.

Step 3.1b — Graphify wiring (deterministic, run the helper script):

Same shape as step 3.1a but for the Graphify integration. Once scripts/sync-graphify-wiring.py has been copied from the template (in step 1), invoke it from the project root:

python3 scripts/sync-graphify-wiring.py "$TEMPLATE/.claude/settings.json"

The script does TWO things atomically:

1. Wiring — removes every existing graphify-related hook entry from the project's hooks block (both the PreToolUse Bash nudge and the PostToolUse Bash telemetry entry) and replaces them with the template's exact set.
2. Scripts on disk — copies every scripts/graphify-*.sh from the template into the project (graphify-bootstrap.sh, graphify-fire-hook.sh, graphify-stats.sh), and deletes any in the project that the template no longer ships.

Both wiring entries are universally safe to inject — the PreToolUse nudge guards on [ -f graphify-out/graph.json ] and silently no-ops when the graph is missing, and the PostToolUse hook bails out cleanly when the command isn't a graphify (query|path|explain|update) invocation. So wiring is decoupled from whether the project has actually bootstrapped Graphify yet.

Finally it verifies that every wired graphify hook has its script on disk and exits non-zero if anything is off. If step 3.1b exits non-zero, do NOT continue — investigate and rerun.

Do NOT try to merge graphify hook entries by hand. The historical prose approach ("add this snippet to your settings.json's Bash matcher block") dropped silently in roughly one project in ten, producing the juradrop / ighweld-2026 pattern: scripts copied, PreToolUse nudge in place, but the PostToolUse telemetry entry missing and the fire log never accumulating. The script removes the ambiguity.

Step 3.1c — Graphify bootstrap (cross-platform, deterministic, builds the graph):

After step 3.1b wires the project, run the bootstrap to actually install Graphify and extract the AST. The bootstrap is independent of the wiring — wiring can be present without a graph (entries no-op until the graph exists), but the inverse is not useful, so 3.1c runs whenever 3.1b succeeds:

bash scripts/graphify-bootstrap.sh

The script:

1. Counts eligible source files (.cs/.ts/.tsx/.js/.jsx/.py/.go/.rs/...) excluding vendored dirs. Skips silently if under 30 — Graphify install overhead exceeds savings on small projects.
2. Ensures pipx is on PATH. Self-installs via brew/apt-get/dnf/pacman/zypper (Linux/macOS) or scoop/winget/choco (Windows Git Bash); falls back to python3 -m pip install --user pipx. Exits non-zero with a platform-specific install hint if all paths fail.
3. Installs graphifyy via pipx if graphify is not already on PATH.
4. Runs graphify install --project to write the Graphify skill + PreToolUse hook to .claude/. Skips if .claude/skills/graphify/SKILL.md already exists.
5. Runs graphify update . for the initial AST extraction (NOT graphify . — the bare command requires an LLM API key; update is AST-only and offline). Skips if graphify-out/graph.json already exists.
6. Runs graphify hook install for git post-commit / post-checkout auto-rebuild. Skips if already installed.
7. Appends graphify-out/ and .claude/graphify-*.log to .gitignore if missing.

After bootstrap, verify with the exit-condition snippet — this is the gate that confirms wiring + scripts + graph are all in place:

command -v graphify && test -f graphify-out/graph.json && test -x scripts/graphify-fire-hook.sh && grep -q 'graphify-fire-hook.sh' .claude/settings.json && echo "[OK] graphify wired" || echo "[FAIL] something missing"

If this prints [FAIL] the sync is incomplete — do NOT continue. Inspect which check fired and rerun the relevant step (3.1b for missing scripts/wiring, 3.1c for missing graph).

Step 3.2 — non-local-LLM hook entries and other settings (merge):

For everything else in settings.json:

• MERGE permissions.deny lists (union of both).
• MERGE permissions.allow lists (union of both) — the template's allow list has expanded git/gh entries (git push:*, git pull:*, git fetch:*, git checkout:*, git switch:*, git branch:*, git merge:*, git rebase:*, git stash:*, git tag:*, git restore:*, git cherry-pick:*, git status:*, git diff:*, git log:*, git show:*, git blame:*, git remote:*, git config --get:*, git config --list:*, gh pr:*, gh issue:*, gh repo view:*, gh run view:*) which the project should pick up.
• If permissions.ask contains Bash(git push *), REMOVE it (the template has moved this to allow). Other permissions.ask entries are preserved.
• MERGE non-local-LLM hooks entries — add missing hooks from the template, preserve existing custom hooks.
• Preserve any project-specific settings not in the template.

Step 3.2.1 — inline-hook OVERWRITE exceptions (the template version wins):

The merge rule above defaults to preserving customizations, but the following inline hooks have intentionally evolving behavior and MUST be replaced with the template version verbatim — do NOT preserve the project's older copy even if it differs. Match each by the unique grep pattern inside its command string and overwrite the entire hook object with the template version:

Hook	Match by command containing	Why it must be overwritten
UserPromptSubmit speckit pipeline mandate	speckit[.:_-](specify|plan|tasks|implement) or speckit[.:_-](specify|clarify|plan|tasks|implement)	Pipeline phase list evolves; new steps (e.g. /clarify between specify and allium, /speckit.analyze between tasks and implement) get added over time. The template version mandates /clarify immediately after /specify on every track and /allium:elicit after /clarify on full/light tracks — if the project's hook is missing the clarify step, overwrite it.
UserPromptSubmit speckit.analyze auto-apply	speckit[.:_-](analyz|analys)	Behavior changed from "Reply suggest & apply for all" UX to immediate auto-apply + auto-chain to /speckit.implement. The old UX must be removed, not preserved.
UserPromptSubmit speckit.clarify auto-pick	speckit[.:_-]clarif	New hook (auto-picks Recommended). Add if missing; if present in any older form, replace with the template version.
PostToolUse Edit|Write spec-completeness type:"prompt"	INTERACTIVE UI or always approve and use systemMessage for the reminder	The LLM-judgment version was observed BLOCKING edits on specs that legitimately carved destructive tests to a later slice (the prompt said "Do NOT block" but the model overrode it under pressure from CLAUDE.md / memory rules). Replace the entire prompt-hook object with the template's type:"command" entry pointing at scripts/spec-md-coverage-reminder-hook.sh. The new script is deterministic, can never issue a permissionDecision, and detects carve-out phrases ("carved to", "out-of-scope", "deferred to", etc.) to suppress false-positive reminders.

If you find a project's settings.json has the OLD analyze hook (containing the phrase Reply **suggest & apply for all** or analyze.md Step 8 default of asking before applying.), this is the legacy version — overwrite it. Mention the overwrite in the step-6 report so the user knows the analyze behavior has flipped from semi-manual to fully auto.

If you find a project's settings.json has the OLD spec-completeness prompt hook (a PostToolUse entry with type:"prompt" whose prompt contains INTERACTIVE UI or always approve and use systemMessage for the reminder), this is the legacy LLM-judgment version that was incorrectly blocking edits — overwrite it with the deterministic command hook from the template. Mention the overwrite in the step-6 report so the user knows the spec-completeness check is now deterministic and no longer LLM-mediated.

3a. .gitignore additions

Ensure the project's .gitignore covers these patterns. Add any that are missing:

• .claude/validation/
• .claude/.local-llm-* (draft artifact files written by hooks)
• .claude/local-llm-*.log (per-project telemetry log)
• .claude/local-llm-*.log.errors (telemetry write-error log)
• .claude/projects/ (per-user memory directory — never commit)
• .claude/settings.local.json (per-machine settings)

4. CLAUDE.md handling

Do NOT overwrite the project's CLAUDE.md. Instead:

• Check if the project's CLAUDE.md references .claude/docs/skills.md — if not, update the reference
• Check if .claude/skills/ is mentioned in the file organization section — if not, add it
• Report any sections that differ from the template for manual review

5. Bootstrap caveat

If the project's sync-template/SKILL.md is OLDER than the template's, the current sync run is using outdated instructions. After the run, the project's SKILL.md will have been updated — but the changes you just made followed the OLD rules. Tell the user to re-run /project-update once more so the new rules take effect. If the SKILL.md was already current, this step is a no-op.

6. Report

After syncing, output a summary:

Synced from template (YYYY-MM-DD):
- [CREATED/UPDATED/SKIPPED] .claude/skills/code-review/SKILL.md
- [CREATED/UPDATED/SKIPPED] .claude/agents/dotnet-reviewer.md
- ...

Project-specific files preserved:
- .claude/agents/custom-agent.md
- ...

Manual review needed:
- CLAUDE.md: section X differs from template
- ...
