Safety: No problems traced to this repository code in these checks.
No problems traced to this repository code in these checks.
OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.
A short run cannot establish that code is safe.
Connections show IP addresses; proxies can hide the final hostname.
Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.
Answers recorded for this run
- PONYTAIL_DEFAULT_MODE sets the default level: Real input produced the expected result: level: ultra
Source: An optional `~/.config/ponytail/config.json` or `PONYTAIL_DEFAULT_MODE` env var can set the default level, but nothing is required.
Input: PONYTAIL_DEFAULT_MODE=ultra
Expected: activation text reports level ultra
Command: env PONYTAIL_DEFAULT_MODE=ultra CLAUDE_CONFIG_DIR=/tmp/ponytail-claude-cfg node hooks/ponytail-activate.js
Observed: level: ultra # Ponytail You are a lazy senior developer. The best code is the code never written. You solve the whole problem with the least new code. End your reply with one or two lines: what you skipped or did not check, and any risk the user must know. Active for the whole session until the user says "stop ponytail" or "normal mode". Switch level: `/ponytail lite|full|ultra`. ## Before you write Read the task and the code it touches. List every place your change must reach: callers, tests, fixtures, config, exports. Check what your change could break for users: data it would destroy o
- Startup text shows the current mode: Real input produced the expected result: level: full
Source: Startup and mode-change text shows the current mode.
Input: no PONYTAIL_DEFAULT_MODE set
Expected: activation text reports level full (the default)
Command: env -u PONYTAIL_DEFAULT_MODE CLAUDE_CONFIG_DIR=/tmp/ponytail-claude-cfg node hooks/ponytail-activate.js
Observed: level: full # Ponytail You are a lazy senior developer. The best code is the code never written. You solve the whole problem with the least new code.

Examples
- CI rule-copy check passes: command completed successfully
Source: .github/workflows/test.yml
Input: repo at pinned commit
Expected: Rule copies match AGENTS.md; 10 rule invariants present
Command: node scripts/check-rule-copies.js
Observed: Rule copies match AGENTS.md; 10 rule invariants present in SKILL.md and AGENTS.md.
- Examples are illustrative outputs, not runnable programs: examples/ holds markdown before/after code samples with no runnable entrypoint; the runnable offline checks are the node test suite (CI runs node --test; 144/144 passed with pandas installed in /tmp/venv-ponytail) and the rule-copy check above
Source: examples/README.md
Expected: documented command completes successfully
Observed: examples/ holds markdown before/after code samples with no runnable entrypoint; the runnable offline checks are the node test suite (CI runs node --test; 144/144 passed with pandas installed in /tmp/venv-ponytail) and the rule-copy check above
