Prerequisite: full use remains untested. This is not a repo defect.
No Claude Code login or Anthropic API key in the disposable guest, so the orchestration behaviour cannot run end to end.
Step: claude -p in the guest: 'Not logged in · Please run /login'. Needed for any real plugin session.

]Answers recorded for this run
- Installing the plugin with the README command registers fable-baton as installed: Real input produced the expected result: fable-baton@fable-baton
Source: /plugin install fable-baton@fable-baton
Input: none (the marketplace was added from realgarit/fable-baton and the plugin installed)
Expected: claude plugin list shows fable-baton@fable-baton
Command: claude plugin list
Observed: fable-baton@fable-baton Version: 1.5.3 Scope: user Status: ✔ enabled
- The SessionStart hook injects the orchestration policy into a new session: Real input produced the expected result: # Orchestration policy (fable-baton)
Source: A SessionStart hook injects the orchestration policy into every new session.
Input: {} on stdin with CLAUDE_PLUGIN_ROOT=.
Expected: hook prints the orchestration policy header
Command: env CLAUDE_PLUGIN_ROOT=. bash hooks/session-start.sh
Observed: # Orchestration policy (fable-baton) You are the senior decision-maker in this session. Your value is judgment, not labor: spend your own reasoning only where being the strongest model changes the outcome, and delegate the rest to the tiered agents below via the Agent tool. ## You keep Intent, scope, architecture and approach, decomposition and ordering, tradeoffs (speed/quality/risk/scope), hidden-risk identification, resolving disagreement between agents, reviewing important outputs, deciding when work is good enough, and the final answer to the user. ## You delegate Work whose result i
- The per-prompt reminder prints a delegation check on each prompt: Real input produced the expected result: [fable-baton] Delegation check for this turn
Source: Every prompt gets a short delegation reminder, and when the model does too much inline work in a row, the counter steps in:
Input: UserPromptSubmit payload with session_id baton-cycle-check and a prompt
Expected: hook prints the [fable-baton] delegation check
Command: bash hooks/prompt-nudge.sh
Observed: [fable-baton] Delegation check for this turn: searching, reading files, editing, testing, and verifying go to agents (scout, executor, architect, verifier via the Agent tool); you keep judgment, decisions, and the final answer. Tripwire: reaching for a 3rd consecutive inline Bash/Read/Grep/Edit call means that block belongs to an agent. Skills define what to do, not who does it: delegate their mechanical steps too. Exempt: conversational turns, one quick lookup, a one-line edit. No exemptions in security-context sessions.
- Whether the plugin fires inside a logged-in session cannot be tested in this guest: Requires a logged-in Claude Code session with a Fable 5 or Opus subscription or API key; the guest reports 'Not logged in' and no credentials were obtained.
Source: Install once and every new session in every repo starts this way.
Observed: Requires a logged-in Claude Code session with a Fable 5 or Opus subscription or API key; the guest reports 'Not logged in' and no credentials were obtained.
Examples
- Repository's own offline hook test (run by CI) passes: command completed successfully
Source: AGENTS.md
Input: tests/packaged-hooks.py
Expected: PASS line for installed hooks with stripped modes
Command: python3 tests/packaged-hooks.py
Observed: PASS: all registered hooks work with mode 644 and spaces in the installed path
Cycles
- The per-prompt reminder runs on every user prompt: Triggered one cycle by hand (run-once: the UserPromptSubmit hook command fired by hand with a prompt payload on stdin; no real Claude Code session; normal trigger: UserPromptSubmit event, once per user prompt): [fable-baton] Delegation check for this turn: searching, reading files, editing, testing, and verifying go to agents (scout, executor, architect, verifier via the Agent tool); you keep judgment, decisions, and the final answer. Tripwire: reaching for a 3rd consecutive inline Bash/Read/Grep/Edit call means that block belongs to an agent. Skills define what to do, not who does it: delegate their mechanical steps too. Exempt: conversational turns, one quick lookup, a one-line edit. No exemptions in security-context sessions.
Source: hooks/hooks.json
Input: {"session_id":"baton-cycle-check","prompt":"hello"}
Expected: reminder printed once for the prompt
Command: bash hooks/prompt-nudge.sh
Observed: [fable-baton] Delegation check for this turn: searching, reading files, editing, testing, and verifying go to agents (scout, executor, architect, verifier via the Agent tool); you keep judgment, decisions, and the final answer. Tripwire: reaching for a 3rd consecutive inline Bash/Read/Grep/Edit call means that block belongs to an agent. Skills define what to do, not who does it: delegate their mechanical steps too. Exempt: conversational turns, one quick lookup, a one-line edit. No exemptions in security-context sessions.
Suggested next step (agent-reported): Run the same steps in a guest with a Claude Code login (or ANTHROPIC_API_KEY) and Node 22+, then start a session, run baton-setup, and check that the agents and the [fable-baton] notices appear.
What the agent did
Install the fable-baton Claude Code plugin from the README and run its hooks (policy at session start, per-prompt delegation reminder, inline-call counter).
