安全使用建议
This skill appears to be what it says: a read-only local sentinel that checks two ~/.willow JSON files and prints a simple status. Before installing, consider: 1) Confirm python3 is available on your agent host (the script uses python3 but the metadata only lists bash). 2) The script intentionally 'fails open' (missing/unreadable files default to STATUS_OK) — if you prefer safer behavior, modify it to fail closed or surface an explicit error instead of allowing large operations to continue. 3) Ensure the ~/.willow files are stored with appropriate file permissions (they contain local session state). 4) The sentinel doesn't invoke remote services or exfiltrate data, but it does advise you to call other skills (/strategic-compact, /handoff); review those skills' permissions before following escalation steps.
功能分析
Type: OpenClaw Skill
Name: willow-context-sentinel
Version: 1.0.0
The willow-context-sentinel skill is a diagnostic utility designed to help the AI agent manage its context window by monitoring local state files (~/.willow/anchor_state.json). The shell script (check_context.sh) performs read-only operations to check prompt counts and service status, using standard Python JSON parsing without any signs of data exfiltration, malicious execution, or harmful prompt injection.
能力评估
Purpose & Capability
The skill is a local context sentinel that reads Willow state files under the user's home directory to decide CONTEXT_OK / COMPACT_NOW / HANDOFF_NOW / POSTGRES_DOWN. The required binary (bash) matches the runtime use. The only small mismatch is that the script invokes python3 but python3 is not declared in the metadata; otherwise the resources requested align with the described purpose.
Instruction Scope
Instructions and the script are narrowly scoped to reading ~/.willow/anchor_state.json and ~/.willow/session_anchor.json and printing a single-line status. The SKILL.md and script consistently describe read-only behavior. Note: the skill intentionally 'fails open' (missing or unreadable files default to STATUS_OK) which is an operational choice that can hide context problems; also SKILL.md examples reference calling other skills (/strategic-compact, /handoff) but the sentinel itself only outputs a status and does not invoke those skills.
Install Mechanism
Instruction-only skill with a small shipped shell script; no install spec, no downloads, and nothing written to disk beyond the included code file. Low install risk.
Credentials
The skill requests no environment variables or credentials. It reads files in $HOME/.willow, which is appropriate for a Willow-specific sentinel. One minor proportionality issue: the script uses python3 for JSON parsing but python3 is not declared as a required binary in the skill metadata.
Persistence & Privilege
always is false and the skill does not request persistent or elevated privileges, nor does it modify other skills or system configuration. Autonomous model invocation is allowed by default but that is normal and the skill's behavior is read-only.

版本历史
v1.0.0
Initial release of context sentinel cascading protocol for Willow/OpenClaw on Linux:
- Monitors `prompt_count` to detect session context usage.
- Outputs one of four statuses: `STATUS_OK`, `COMPACT_NOW`, `HANDOFF_NOW`, or `POSTGRES_DOWN`.
- Directs automatic invocation of `strategic-compact` or `handoff` workflows when limits are reached.
- Checks Postgres availability via `session_anchor.json`.
- Safe, read-only operation; integrates easily with session heartbeat processes.
