claude-supervision

claude-supervision is a skill for Claude Code from drippy-passport968/agent-supervision-skills. It costs 117 tokens per session (7,077 once invoked), scanned A, original, MIT.

A workflow for handing coding tasks to the local Claude Code command-line tool and checking its work afterward. It stores the result and examines the files and claims instead of accepting the handoff without review.

In plain words
What is it for?
Use it to delegate coding, resume multi-step work, run background sessions, or request structured output and code reviews from Claude Code. It requires PowerShell 7+, the Claude Code CLI, and authentication.
Why use it?
It provides a way to use Claude Code for substantial or background tasks while keeping an independent check on what actually happened. It also covers setup, authentication, time limits, and recovery of session output.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

ModelPer sessionOnce invoked
Fable 5.1 $0.00117 $0.07077
Opus 5.5 $0.00047 $0.02831

Security

Grade A, and why

claude-supervision scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/claude-bg.ps1, scripts/claude-list-sessions.ps1, scripts/claude-review.ps1, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 491 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Claude Supervision

Hand work to the local claude CLI (Anthropic's Claude Code) and supervise the result — read what Claude actually did, inspect artifacts, verify claims, only then answer the user.

Supervision, not blind delegation.

This is the Claude-Code analog of kimi-supervision and codex-supervision. Use it when you (Codex, another Claude session, a CI script, etc.) want to delegate to Claude Code non-interactively and need the answer + artifacts in a structured place.

Requirements

  • PowerShell 7+ (pwsh.exe). claude-setup.ps1 refuses to mark ready=true on PS 5.1.
  • Claude Code CLI (claude from @anthropic-ai/claude-code). Install: npm install -g @anthropic-ai/claude-code.
  • Authentication: claude auth login (interactive once), OR $env:ANTHROPIC_API_KEY / $env:ANTHROPIC_AUTH_TOKEN. Verified by claude auth status (JSON output, exit 0=in / 1=out).

What this skill provides

Scripts under scripts/:

  • common.ps1 — claude path resolution, env hygiene, async I/O, timeout, artifact capture, secret-redacted CLI arg recording, native session JSONL recovery (reads ~/.claude/projects/<encoded-cwd>/<uuid>.jsonl when stdout is unexpectedly empty)
  • claude-setup.ps1 — claude auth status JSON probe + PS 7+ + writable state dir
  • claude-task.ps1 — delegate a task via claude --print (foreground, blocking)
  • claude-review.ps1 — multi-agent cloud-hosted review via claude ultrareview
  • claude-bg.ps1 — manage background sessions: --bg / agents / logs / stop / respawn / rm / daemon status
  • claude-list-sessions.ps1 — inspect this wrapper's own session artifacts

These scripts:

  • prefer the native claude.exe at $USERPROFILE\.local\bin\ (no .cmd shim chain → no Windows stdio race like codex)
  • read/write UTF-8 throughout; set Console.OutputEncoding to UTF-8
  • pass the prompt via stdin (no argv length limits, no quoting hell on multi-line/unicode text)
  • async stdout/stderr reads with ReadToEndAsync (no pipe-buffer deadlock)
  • -TimeoutSec with hard kill (Process.Kill($true) with Kill() fallback for older runtimes) and classification='timeout'
  • always write last-prompt.txt, last-response.txt, stderr.log, session.json to the session dir
  • session ID format YYYYMMDD-HHmmss-fff-<PID>-<rand>-<mode> (no same-millisecond collisions)
  • redact secrets in --settings / --mcp-config / --agents / --json-schema / --*-system-prompt inline JSON before serializing to session.json
  • truncate long inline JSON args in session.json for readability

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
