setup-target

You are performing a one-shot setup that writes the required Claude Code permission rules into a target repository's .claude/settings.json. This skill does not analyse code, dispatch agents, or modify repository content beyond .claude/settings.json.

Step 1 — Parse arguments

Recognized flags:

--repo <path> --output <path> --plugin-dir <path> --scope <scope>

Parse these and set REPO_ROOT, OUTPUT_DIR, PLUGIN_DIR, SCOPE. Default REPO_ROOT to the current working directory (do NOT fall back to the plugin repo root — this skill is always about a target repo, not the plugin itself). Default OUTPUT_DIR to $REPO_ROOT/docs/security. Default SCOPE to project (writes <repo>/.claude/settings.json — committed by the repo maintainer so all contributors get prompt-free runs automatically).

Reject unknown arguments (hard fail)

If the invocation contains any token that is not one of the recognized flags above — or is not the value consumed by --repo / --output / --plugin-dir / --scope — DO NOT proceed. Print the block below verbatim to stderr, substituting <TOKEN>, then exit with status 2:

Error: unknown argument '<TOKEN>'

/appsec-advisor:setup-target accepts only:
  --repo <path>        Target repository to configure (default: cwd)
  --output <path>      Output directory for scan artefacts (default: <repo>/docs/security)
  --plugin-dir <path>  Plugin install directory (default: $CLAUDE_PLUGIN_ROOT)
  --scope <scope>      Settings scope: project (default) | local | user
                         project → <repo>/.claude/settings.json        (committed, shared; default)
                         local   → <repo>/.claude/settings.local.json  (gitignored, personal)
                         user    → ~/.claude/settings.json             (global, all projects)

Run `/appsec-advisor:setup-target --help` for details.

Step 2 — Create the .claude directory if absent

mkdir -p "$REPO_ROOT/.claude"

Step 3 — Write the permissions

Call check_permissions.py with --update so it merges the required entries (and promotes any user-only entries to project scope):

python3 "$CLAUDE_PLUGIN_ROOT/scripts/check_permissions.py" \
  --repo-root "$REPO_ROOT" \
  --output-dir "$OUTPUT_DIR" \
  --plugin-dir "$PLUGIN_DIR" \
  --scope "$SCOPE" \
  --update

Capture stdout, stderr, and exit code.

Step 4 — Report

If the helper exited 0, print its stdout verbatim, then add exactly one line:

Restart Claude Code (or reload the session) in <REPO_ROOT> for the new permissions to take effect.

If the helper exited non-zero, print its stderr verbatim and exit with the same code.

Do NOT add any other text — no preamble, no summary, no closing remark.
