phase-exec

phase-exec is a command for Claude Code from ngtiendong/Academic-Research-Agent-Skill. It costs 0 tokens per session (136 once invoked), scanned A, original, MIT.

A controlled procedure for carrying out one phase from an agent brief, which is a written plan for the agent's work. It checks the approved scope and Reality Gate decision before editing, then reports changes, checks, results, blockers, and next steps.

In plain words
What is it for?
Use it to execute an approved phase, edit only relevant files, run focused checks, stop at defined conditions, and record the outcome.
Why use it?
It keeps research or engineering work limited to what has been approved and prevents a small smoke test from being treated as proof that a larger scientific project will work.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 136 The whole file, excluding the scripts and references it only reads on demand.

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.

Security

Grade A, and why

phase-exec 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 7d ago.

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.

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.
