Enter Hall session mode. Fetches personas, assembles session stack, activates Old Major.
Use --refresh to force persona re-fetch even if cache is fresh. Use --verify to force invoker re-check.
Execute each step in order. Hard-stop on any error; warn-and-continue on non-critical issues.
Flag pre-processing:
--verify was passed: rm -f .hall-cache/invoker.json--refresh was passed: treat NEED_FETCH=true regardless of the block output below.set -euo pipefail

If STANDALONE=true: read skills/hall-open/standalone-flow.md (resolve against $CLAUDE_PLUGIN_ROOT) and execute the org/repo resolution procedure exactly as specified. On completion, ORG, REPO_NAME, and REPO are set for subsequent steps.
Read CURRENT_SHA from .hall-cache/session/.current-sha; if absent, call get_file_contents MCP (owner=MockaSort-Studio, repo=hall-of-automata, path=agents.yml) and extract sha.

Call get_file_contents MCP: owner=MockaSort-Studio, repo=hall-of-automata, path=roster/. From the returned array, keep entries where type=file, name ends in .md, name ≠ old-major.md and ≠ README.md. Write the names (without .md) as a JSON array to .hall-cache/personas/.advisory-roster.json.
# On rate_limit/secondary-rate-limit error: gh api repos/MockaSort-Studio/hall-of-automata/contents/roster --jq '[.[] | select(.type=="file" and (.name|endswith(".md")) and .name!="old-major.md" and .name!="README.md") | .name[:-3]]' > .hall-cache/personas/.advisory-roster.json

Fetch and write persona files via Bash (the Write tool fails on new files; gh api writes directly):

--refresh limitation: Stack changes regenerated in --refresh don't take effect in the current context window — the @-import chain is evaluated only at conversation start. A fresh cc session is required for persona or methodology changes to apply. See Step 5.
Read skills/hall-open/session-setup.md (resolve against $CLAUDE_PLUGIN_ROOT) and execute the session setup procedure exactly as specified.
Read the first 30 lines of README.md and write a 2–4 sentence brief to .hall-cache/session/context.md. If no README: Project context: not available.
Standalone mode: if STANDALONE=true, call get_file_contents MCP (owner=$ORG, repo=$REPO_NAME, path=CLAUDE.md). On success, write decoded content to ~/.hall/context/target-claude.md; incorporate as supplemental project context in context.md. On 404: skip silently; synthesise from README only.
Read .hall-cache/session/CLAUDE-stack.md and each @-imported file in order; apply as operating instructions. Skip if resume mode and --refresh was not passed — stack already loaded via CLAUDE.md @-imports. On --refresh: always run this step regardless of mode; @-import chains are not re-evaluated mid-session, so the explicit read makes regenerated stack content active immediately.
Read skills/hall-open/invoker-gate.md (resolve against $CLAUDE_PLUGIN_ROOT) and execute the invoker detection procedure exactly as specified.
ls .hall-cache/plans/ 2>/dev/null || true
List existing plans with status. Ask whether to resume or start fresh. Then ask what the invoker wants to build — one sentence, in character as Old Major.
