Set up foundry on new machine:

Action	What happens
Detect Python 3.10+ (python / py -3 / python3); install ~/.local/bin/python shim if needed	✓
Merge statusLine, permissions.allow, enabledPlugins, advisorModel → ~/.claude/settings.json	✓
rules/*.md → ~/.claude/rules/	symlink
TEAM_PROTOCOL.md → ~/.claude/	symlink
skills/* → ~/.claude/skills/	symlink
hooks/hooks.json	auto — plugin system
Conflict review before overwriting existing user files	✓

Why symlink rules and skills (not copy)? Rules, TEAM_PROTOCOL.md, and skills load at session startup. Symlinks = every session gets plugin's current version — no stale copies, no re-run after upgrades. Broken symlink after upgrade = obvious error; stale copy silently serves old content.

Why symlink skills explicitly? claude plugin install creates ~/.claude/skills/ symlinks on first install but does NOT update them on upgrade — old version directory stays in cache, symlinks go stale. Setup's stale-version detection (same pattern as rules) replaces them silently on every re-run.

Why not symlink agents? Agents must use full plugin prefix (foundry:sw-engineer, not sw-engineer) for unambiguous dispatch. Plugin system exposes agents at foundry: namespace — no ~/.claude/agents/ symlinks needed. (Stale agent symlinks from prior installs removed by setup's Phase 1 cleanup.)

Why hooks need no action? hooks/hooks.json inside plugin registers automatically when plugin enabled. Setup's only hook-adjacent step: write statusLine.command path (Step 4) — statusLine is top-level settings key, not part of hooks.json.

NOT for: editing project .claude/settings.json (Step 8 READS it to propagate advisorModel, never writes it).

• No arguments — interactive mode; prompts on conflicts.
• --approve — non-interactive mode; auto-accepts all recommended answers. Use for scripted or CI setups.

Flag detection

Parse $ARGUMENTS for --approve (case-insensitive). If found, set APPROVE_ALL=true; else APPROVE_ALL=false.

Early git repository check — Step 6 requires a git repository. In --approve mode there is no interactive fallback, so check immediately before Step 1:

if [ "$APPROVE_ALL" = "true" ] && [ ! -e ".git" ]; then
    printf "! --approve requires git repository — run from project root\n"
    exit 1
fi

When APPROVE_ALL=true, every AskUserQuestion below skipped — ★ recommended option applied automatically. Print [--approve] auto-accepting recommended option in place of question.

Unsupported flag check — after all supported flags extracted, scan $ARGUMENTS for remaining --<token> tokens. If found: print ! Unknown flag(s): \--`. Supported: `--approve`.then invokeAskUserQuestion` — (a) Abort (stop, re-invoke with correct flags) · (b) Continue ignoring (skip unknown flags, proceed). On Abort: stop.

Python detection

Probe Python 3.10+ — required before any bin/*.py calls. Windows Store stub returns exit 9009 when given args; caught by 2>/dev/null:

PYTHON_CMD=""
SHIM_DIR="$HOME/.local/bin"
if command -v python >/dev/null 2>&1 && python --version 2>/dev/null | grep -qE "Python 3\.(1[0-9]|[2-9][0-9])"; then
    PYTHON_CMD="python"
elif command -v py >/dev/null 2>&1 && py -3 --version 2>/dev/null | grep -qE "Python 3\.(1[0-9]|[2-9][0-9])"; then
    PYTHON_CMD="py -3"
    mkdir -p "$SHIM_DIR"
    printf '#!/usr/bin/env bash\npy -3 "$@"\n' > "$SHIM_DIR/python"
    chmod +x "$SHIM_DIR/python"
    printf "  Python shim installed: %s/python → py -3\n" "$SHIM_DIR"
elif command -v python3 >/dev/null 2>&1 && python3 --version 2>/dev/null | grep -qE "Python 3\.(1[0-9]|[2-9][0-9])"; then
    PYTHON_CMD="python3"
    mkdir -p "$SHIM_DIR"
    printf '#!/usr/bin/env bash\npython3 "$@"\n' > "$SHIM_DIR/python"
    chmod +x "$SHIM_DIR/python"
    printf "  Python shim installed: %s/python → python3\n" "$SHIM_DIR"
else
    printf "! Python 3.10+ not found — install Python 3.10+ and re-run /foundry:setup\n"
    exit 1
fi
printf "  Python: %s\n" "$PYTHON_CMD"

# ~/.local/bin is XDG-standard but not always on PATH
if [ -f "$SHIM_DIR/python" ] && ! echo ":$PATH:" | grep -q ":$SHIM_DIR:"; then
    printf "  ⚠ %s not on PATH — add to shell rc:\n      export PATH=\"\$HOME/.local/bin:\$PATH\"\n" "$SHIM_DIR"
fi

~/.local/bin is XDG-standard user-bin directory on modern macOS/Linux. Shim created only when python absent or resolves to Store stub. Idempotent — re-running setup overwrites shim with same content. If ~/.local/bin not yet on $PATH, setup prints export PATH="$HOME/.local/bin:$PATH" line for user's shell rc.

Step 1: Locate the installed plugin

Resolve validated install root via canonical resolver — registry lookup, cache-scan fallback (skips .orphaned_at, newest by semver), and both security gates (under cache dir + plugin.json name match) live in the script; do not re-implement inline:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
PLUGIN_ROOT=$(python "${CLAUDE_PLUGIN_ROOT:-plugins/cc_foundry}/bin/resolve_plugin_root.py" --plugin-name foundry 2>/dev/null)  # timeout: 15000
case $? in
    0) ;;
    2) echo "! SECURITY: resolve_plugin_root.py rejected the candidate root — aborting setup"; exit 1 ;;
    *) PLUGIN_ROOT="" ;;  # not found; handled by empty-check below
esac
echo "$PLUGIN_ROOT" > "${TMPDIR:-/tmp}/setup-plugin-root-${CSID}"  # persist for later blocks (Check 41)

If $PLUGIN_ROOT empty after both attempts, stop and report: "foundry plugin not found — install it first with: claude plugin marketplace add Borda/AI-Rig && claude plugin install foundry@borda-ai-rig"

Confirm $PLUGIN_ROOT/hooks/statusline.js exists. If not, stop and report.

Step 2: Back up settings.json

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
SETUP_BAK_TS=$(date -u +%Y%m%dT%H%M%SZ)
[ -f ~/.claude/settings.json ] || printf '{}\n' > ~/.claude/settings.json  # create empty in-bash if absent — no Write-tool permission prompt (headless-safe)
cp ~/.claude/settings.json "$HOME/.claude/settings.json.bak-${SETUP_BAK_TS}"  # timeout: 5000
echo "$SETUP_BAK_TS" > "${TMPDIR:-/tmp}/foundry-setup-bak-ts-${CSID}"  # persist for restore in Step 9

Report: "Backed up ~/.claude/settings.json → ~/.claude/settings.json.bak-"

Step 3: Check for stale hooks block

jq -e 'has("hooks")' ~/.claude/settings.json >/dev/null 2>&1  # timeout: 5000

If hooks key exists, user has pre-plugin-migration settings block — hooks fire twice.

If APPROVE_ALL=true: print [--approve] auto-accepting: remove stale hooks block and proceed to remove (apply option a below).

Otherwise, use AskUserQuestion:

(a) Remove stale hooks block now ★ recommended (backup in place from Step 2) (b) Skip — I'll handle manually

On (a): strip hooks key in-bash (no Write tool), continue:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
_jq_result=$(jq 'del(.hooks)' ~/.claude/settings.json)  # timeout: 5000
[ $? -eq 0 ] && [ -n "$_jq_result" ] && printf '%s\n' "$_jq_result" > "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" && mv "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" ~/.claude/settings.json || { printf "! jq failed stripping hooks — settings.json unchanged\n"; exit 1; }

On (b): warn "Double-firing risk: existing hooks block will fire alongside plugin-registered hooks." Continue.

Step 4: Merge statusLine

Check if statusLine already points to the current plugin's statusline.js (filename match alone is insufficient — a stale entry from an older plugin version survives upgrades and silently runs the previous hook). Verify both that the command contains statusline.js AND that the $PLUGIN_ROOT path (with its version segment) appears in the command string:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
IFS= read -r PLUGIN_ROOT < "${TMPDIR:-/tmp}/setup-plugin-root-${CSID}" 2>/dev/null || PLUGIN_ROOT=""  # reload (Check 41)
jq --arg root "$PLUGIN_ROOT" -e '
    (.statusLine.command // "") as $cmd
    | ($cmd | contains("statusline.js")) and ($cmd | contains($root))
' ~/.claude/settings.json >/dev/null 2>&1  # timeout: 5000

If already set to the current $PLUGIN_ROOT: report "statusLine already set to current plugin version — skipping." If a stale entry exists (statusline.js present but $PLUGIN_ROOT does not match), the check returns non-zero and the merge below overwrites with the current path. Otherwise:

Writes statusLine key to ~/.claude/settings.json:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
_jq_result=$(jq --arg cmd "node \"$PLUGIN_ROOT/hooks/statusline.js\"" \
    '.statusLine = {"async":true,"command":$cmd,"type":"command"}' \
    ~/.claude/settings.json)  # timeout: 5000
[ $? -eq 0 ] && [ -n "$_jq_result" ] && printf '%s\n' "$_jq_result" > "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" && mv "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" ~/.claude/settings.json || { printf "! jq failed updating statusLine — settings.json unchanged\n"; exit 1; }

Writeback happens in-bash above (mv — no Write-tool permission prompt, headless-safe). Report: statusLine: set to current plugin version.

Step 5: Merge permissions.allow and permissions.deny

Merge $PLUGIN_ROOT/.claude-plugin/permissions-allow.json into ~/.claude/settings.json via jq below — add only entries not already present (exact string match):

Writes merged permissions.allow array:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
_jq_result=$(jq --slurpfile perms "$PLUGIN_ROOT/.claude-plugin/permissions-allow.json" \
    '.permissions.allow = ((.permissions.allow // []) + $perms[0] | unique)' \
    ~/.claude/settings.json)  # timeout: 5000
[ $? -eq 0 ] && [ -n "$_jq_result" ] && printf '%s\n' "$_jq_result" > "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" && mv "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" ~/.claude/settings.json || { printf "! jq failed merging permissions.allow — settings.json unchanged\n"; exit 1; }

Writeback happens in-bash above (mv). Report: "Added N new permissions.allow entries (M already present)."

Check whether $PLUGIN_ROOT/.claude-plugin/permissions-deny.json exists. If so, merge via jq below — add only entries not already present:

Writes merged permissions.deny array:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
_jq_result=$(jq --slurpfile deny "$PLUGIN_ROOT/.claude-plugin/permissions-deny.json" \
    '.permissions.deny = ((.permissions.deny // []) + $deny[0] | unique)' \
    ~/.claude/settings.json)  # timeout: 5000
[ $? -eq 0 ] && [ -n "$_jq_result" ] && printf '%s\n' "$_jq_result" > "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" && mv "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" ~/.claude/settings.json || { printf "! jq failed merging permissions.deny — settings.json unchanged\n"; exit 1; }

Writeback happens in-bash above (mv). Report: "Added N new permissions.deny entries (M already present)."

Step 6: Copy permissions-guide.md

Note: this step writes to .claude/permissions-guide.md relative to the current working directory — setup must be run from project root (a git repository root). Guard:

[ -e ".git" ] || { printf "! BLOCKED — /foundry:setup must run from project root (git repository root)\n"; exit 1; }

Copy $PLUGIN_ROOT/permissions-guide.md to .claude/permissions-guide.md — only if destination absent (preserves project-local edits via /manage):

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
IFS= read -r PLUGIN_ROOT < "${TMPDIR:-/tmp}/setup-plugin-root-${CSID}" 2>/dev/null || PLUGIN_ROOT=""  # reload: fresh shell (Check 41)
if [ ! -f ".claude/permissions-guide.md" ]; then  # timeout: 5000
    cp "$PLUGIN_ROOT/permissions-guide.md" ".claude/permissions-guide.md"
    printf "  copied: permissions-guide.md\n"
else
    printf "  permissions-guide.md already present — skipping\n"
fi

Step 7: Merge enabledPlugins

jq -e '.enabledPlugins["codex@openai-codex"] == true' ~/.claude/settings.json >/dev/null 2>&1  # timeout: 5000

If already true: report "enabledPlugins already set — skipping." Otherwise:

Writes enabledPlugins["codex@openai-codex"] key:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
_jq_result=$(jq '.enabledPlugins["codex@openai-codex"] = true' \
    ~/.claude/settings.json)  # timeout: 5000
[ $? -eq 0 ] && [ -n "$_jq_result" ] && printf '%s\n' "$_jq_result" > "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" && mv "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" ~/.claude/settings.json || { printf "! jq failed updating enabledPlugins — settings.json unchanged\n"; exit 1; }

Writeback happens in-bash above (mv).

Step 8: Merge advisorModel (from project settings)

ADV=""
if [ -f ".claude/settings.json" ]; then
    ADV=$(jq -r '.advisorModel // empty' .claude/settings.json 2>/dev/null)  # timeout: 5000
fi

If $ADV empty: report advisorModel: skipped (not pinned in project .claude/settings.json) and continue.

Check if global already equals it:

jq --arg m "$ADV" -e '.advisorModel == $m' ~/.claude/settings.json >/dev/null 2>&1  # timeout: 5000

If already equal: report advisorModel already set to <value> — skipping.

Otherwise:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
_jq_result=$(jq --arg m "$ADV" '.advisorModel = $m' ~/.claude/settings.json)  # timeout: 5000
[ $? -eq 0 ] && [ -n "$_jq_result" ] && printf '%s\n' "$_jq_result" > "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" && mv "${TMPDIR:-/tmp}/foundry_setup_tmp.json-${CSID}" ~/.claude/settings.json || { printf "! jq failed updating advisorModel — settings.json unchanged\n"; exit 1; }

Writeback happens in-bash above (mv — no Write-tool permission prompt). Report advisorModel: set to <value>.

Step 9: Validate

After all writes, confirm file parses as valid JSON:

jq empty ~/.claude/settings.json  # timeout: 5000

If jq exits non-zero: restore from backup: export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"; IFS= read -r SETUP_BAK_TS < "${TMPDIR:-/tmp}/foundry-setup-bak-ts-${CSID}" 2>/dev/null || SETUP_BAK_TS=$(ls -t "$HOME/.claude/settings.json.bak-"* 2>/dev/null | head -1 | sed 's/.*\.bak-//'); cp "$HOME/.claude/settings.json.bak-${SETUP_BAK_TS}" ~/.claude/settings.json, report error, stop. If valid: continue.

Step 10: Symlink rules and TEAM_PROTOCOL.md

Ensure target dir exists:

mkdir -p ~/.claude/rules  # timeout: 5000

Phase 1 — Remove obsolete foundry-managed symlinks (file/dir removed from current plugin version, or dangling target):

# re-resolve — Bash state not persistent across steps; use installed cache path, not local fallback
PLUGIN_ROOT=$(python "${CLAUDE_PLUGIN_ROOT:-plugins/cc_foundry}/bin/resolve_plugin_root.py" --plugin-name foundry 2>/dev/null)  # timeout: 15000
[ -z "$PLUGIN_ROOT" ] && { printf "! setup Phase 1 — could not resolve PLUGIN_ROOT; run claude plugin install foundry@borda-ai-rig first\n"; exit 1; }
python "$PLUGIN_ROOT/bin/symlink_with_guard.py" cleanup --plugin-root "$PLUGIN_ROOT"  # timeout: 15000

The script iterates rules (*.md), TEAM_PROTOCOL.md, and skill dirs; removes any foundry-managed symlink (target contains borda-ai-rig/foundry/) that is both stale (target does not resolve under $PLUGIN_ROOT) and whose source no longer exists in current plugin tree. Each removal prints removed obsolete: <name> / removed obsolete skill: <name>.

Cleanup also scans ~/.claude/agents/ for foundry-managed symlinks (targets containing borda-ai-rig/foundry/) and removes them unconditionally — foundry agents served directly from plugin namespace, not via ~/.claude/agents/ symlinks. Each removal prints removed obsolete agent: <name>.

Phase 2 — Conflict scan — identify entries needing user confirmation. Stale foundry symlinks (old version → current) are auto-replaced in Phase 4 without prompt:

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
mkdir -p "$HOME/.claude/skills"  # timeout: 5000
mapfile -t LINK_CONFLICTS < <(python "$PLUGIN_ROOT/bin/symlink_with_guard.py" scan --plugin-root "$PLUGIN_ROOT")  # timeout: 30000
printf '%s\n' "${LINK_CONFLICTS[@]}" > "${TMPDIR:-/tmp}/foundry-setup-conflicts-${CSID}.txt"  # timeout: 3000; persist for Phase 4; Bash calls don't share state

The scan mode walks the same three patterns (rules *.md, TEAM_PROTOCOL.md, skill dirs) and prints one conflict per line. Entries surface only when the dest is a real file or a symlink whose target does NOT contain borda-ai-rig/foundry/. Output format matches the legacy bash array entries: rules/<name> → <target> · rules/<name> (real file) · TEAM_PROTOCOL.md → <target> · skills/<name> → <target> · skills/<name> (real entry).

Phase 3 — Handle remaining conflicts (real files or symlinks to non-foundry paths):

If $LINK_CONFLICTS empty: skip to Phase 4.

If APPROVE_ALL=true: print [--approve] auto-accepting: replace all symlink conflicts and replace all (apply option a below). # --approve mode: auto-accept all conflicts; AskUserQuestion skipped

Otherwise, use AskUserQuestion:

These entries in ~/.claude/ would be replaced with symlinks to the foundry plugin:
  - <name>  (<current state>)
  - …

Options:

(a) Replace all ★ recommended (b) Skip all conflicts — keep existing files unchanged (c) Review one by one

On (b): set SKIP_CONFLICTS_MODE=true. On (c): initialize APPROVED_CONFLICT_ENTRIES=() and PER_ITEM_REVIEW_MODE=true. Cap: if ${#LINK_CONFLICTS[@]} > 10, emit warning "⚠ ${#LINK_CONFLICTS[@]} conflicts found — per-item review capped at 10; showing first 10. Run again for the rest." and process only the first 10. Iterate over each entry (up to cap); for each, invoke AskUserQuestion — "Replace <entry>? (a) Yes — replace · (b) Skip — keep existing". On (a): append the entry's identifier (basename for rules, TEAM_PROTOCOL.md, or skill:<name>) to APPROVED_CONFLICT_ENTRIES. On (b): leave it out. After the loop, persist: export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"; printf '%s\n' "${APPROVED_CONFLICT_ENTRIES[@]}" > ${TMPDIR:-/tmp}/foundry-setup-approved-${CSID}.txt. Items not in $LINK_CONFLICTS (current, stale foundry, absent) bypass this gate — handled silently in Phase 4.

Phase 4 — Symlink — for each approved, auto-replaced, or absent entry, ln -sf creates/replaces. Stale foundry symlinks from Phase 2 are included here (auto-replaced silently). Conflict guard depends on which Phase 3 branch fired:

• SKIP_CONFLICTS_MODE=true (option b): skip every entry that is a real file or non-foundry symlink — those are conflicts the user declined.
• PER_ITEM_REVIEW_MODE=true (option c): for entries that appear in $LINK_CONFLICTS, only replace when the entry's identifier is in APPROVED_CONFLICT_ENTRIES; otherwise skip. Entries not in $LINK_CONFLICTS (current / stale foundry / absent) always replace.
• Neither flag (option a or no conflicts): replace unconditionally.

Step 11: Write CLAUDE.src.md → ~/.claude/CLAUDE.md

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
IFS= read -r PLUGIN_ROOT < "${TMPDIR:-/tmp}/setup-plugin-root-${CSID}" 2>/dev/null || PLUGIN_ROOT=""  # reload: fresh shell (Check 41)

cp "$PLUGIN_ROOT/CLAUDE.src.md" "$HOME/.claude/CLAUDE.md"  # timeout: 5000
printf "  wrote: CLAUDE.src.md → ~/.claude/CLAUDE.md\n"

Step 12: Final report

Print summary:

• Python: <PYTHON_CMD> (shim installed at ~/.local/bin/python / already on PATH / n/a)
• statusLine: set / skipped
• permissions.allow: N entries added
• enabledPlugins: set / skipped
• advisorModel: set / skipped
• Rules removed obsolete: N (files no longer in current plugin version)
• Skills removed obsolete: N (skill dirs no longer in current plugin version)
• Agent symlinks removed from ~/.claude/agents/: N (stale foundry-managed symlinks purged)
• Rules linked: N → ~/.claude/rules/
• TEAM_PROTOCOL.md linked → ~/.claude/TEAM_PROTOCOL.md
• Skills linked: N → ~/.claude/skills/
• CLAUDE.md written → ~/.claude/CLAUDE.md
• Backup at: ~/.claude/settings.json.bak

Follow-up gate omitted — setup is one-shot; no iterative follow-up action applies. Step 12 Final report is terminal output; no AskUserQuestion gate required.

Testing setup changes: Setup skill has no .claude/skills/setup entry — only reachable as /foundry:setup after plugin installed. To test: bump version in plugins/cc_foundry/.claude-plugin/plugin.json, run claude plugin install foundry@borda-ai-rig from repo root to refresh cache, invoke /foundry:setup. Upgrade path: After claude plugin install foundry@borda-ai-rig upgrades version, re-run /foundry:setup — Step 10 Phase 1 removes rules and skill symlinks no longer in new version; Phase 2–4 auto-replaces stale foundry symlinks (rules + skills) without prompting; real-file and non-foundry-path conflicts still surfaced for user review. Note: bash sync.sh calls /foundry:setup headlessly at end — skill symlinks updated automatically on every sync run.
