The Agent Skills Directory

[COMMAND_EXECUTION]: The skill configures the Claude Code environment to execute a local shell script (.claude/statusline.sh) via the settings.json configuration file. This is the documented and intended mechanism for implementing custom status bars in the target environment.
[INDIRECT_PROMPT_INJECTION]: The provided status bar script ingests JSON data from the host environment's standard input. While this involves processing external data, the script's capabilities are limited to information display.
- Ingestion points: templates/statusline.sh reads input from standard input using cat and parses it with jq.
- Boundary markers: Absent; the script relies on the expected structure of the environment-provided JSON.
- Capability inventory: The script utilizes standard tools (git, jq, sed, awk) and an optional utility (ccusage) exclusively for read-only status reporting.
- Sanitization: Variable content is handled safely using printf with %s placeholders, which prevents typical command or format string injection during the display phase.
