Install Framework Skill Packs

/scaffold records the user's chosen framework packs in project-manifest.json under framework_skill_packs, then prints normal-terminal install commands. The Claude Code auto-mode classifier blocks external GitHub installs as a safety gate (independent of settings.json allowlist), so this skill does not attempt to run npx skills add from inside Claude Code.

This skill is the one-command path to verify those installs. It is idempotent and safe to run repeatedly.

Pack registry

Manifest key	Repository	Prefix	Expected skills
langchain	cwijayasundara/agent_cli_langchain	langchain-agents-	9
google-adk	google/agents-cli	google-agents-cli-	7

If framework_skill_packs contains a key not in this registry, report it as unknown and skip — do not invent install commands.

Steps

Step 1 — Parse arguments

• --list — report current state. This is the default behavior.

Step 2 — Read project-manifest.json

Locate the manifest at the project root. Extract the framework_skill_packs array.

• Missing field or empty array → print No framework packs configured in project-manifest.json — nothing to install. and stop.
• Field present with one or more entries → proceed.

Step 3 — Build the per-pack status table

For each entry, check whether the prefix matches any directory under .claude/skills/:

COUNT=$(find .claude/skills -maxdepth 1 -type d -name '<prefix>*' | wc -l | tr -d ' ')

State for each pack:

• COUNT >= expected → INSTALLED
• COUNT > 0 && COUNT < expected → PARTIAL (install was interrupted; treat like missing)
• COUNT == 0 → MISSING

If --list was passed, print the table and stop here.

Step 4 — Report missing packs

Do not run npx skills add from this skill. For each pack in MISSING or PARTIAL state, mark it as PENDING MANUAL INSTALL and include it in the manual-install block in Step 6.

If all selected packs are already INSTALLED, print the summary and stop without a manual-install block.

Step 5 — Print summary

Print a compact table:

Pack         Repo                                          Status        Skills
langchain    cwijayasundara/agent_cli_langchain            INSTALLED ✓   9 / 9
google-adk   google/agents-cli                             PENDING       0 / 7  (manual install required)

Step 6 — Manual-install block (when any pack is missing)

For each missing or partial pack, print this verbatim — substituting <repo>, <prefix>, and project-root path:

═══════════════════════════════════════════════════════════════════════════════
  [!] Pack pending manual install: <repo>
═══════════════════════════════════════════════════════════════════════════════

  Open a normal terminal (NOT Claude Code) and run:

    cd <project-root>
    npx --yes skills add <repo> -a claude-code -s '*' -y

  Verify:

    ls .claude/skills/ | grep '^<prefix>'

  Then come back to Claude Code and run `/install-framework-packs` again
  to confirm the install.

═══════════════════════════════════════════════════════════════════════════════

If multiple packs are missing, print one box per pack. The boxes must be the LAST output before the skill exits — they should not be buried under other text.

Step 7 — Update project state (optional)

Write a small status file at .claude/state/framework-packs-install.json recording the last-run timestamp and per-pack state so subsequent runs and Step 10 scaffold reports can read it:

{
  "last_run": "2026-05-13T16:30:00Z",
  "packs": {
    "langchain": { "status": "INSTALLED", "skills": 9, "repo": "cwijayasundara/agent_cli_langchain" },
    "google-adk": { "status": "PENDING MANUAL INSTALL", "skills": 0, "repo": "google/agents-cli" }
  }
}

This is informational only — the skill does not depend on it for correctness; the prefix-directory check is the source of truth.

When NOT to use this skill

• The framework pack is published as a Claude Code marketplace plugin (use enabledPlugins in settings.json instead).
• You want to install a one-off, unregistered pack from a different repository (run npx skills add <repo> -a claude-code -s '*' -y directly instead).
• You're auditing what's installed — --list is fine; otherwise use ls .claude/skills/ directly.

Safety notes

• The skills CLI runs Snyk/Socket/Gen security risk assessments and prints them before installing. Two LangChain pack skills (deepagents-code, deploy) carry a "Med Risk" Snyk flag — surface this when reporting the install result.
• The classifier denial is doing real work: it stops the in-Claude-Code session from quietly running external code. Always route the manual install through the user's own terminal so they see the Snyk warnings and stay in the loop.
