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.

Use it to execute an approved phase, edit only relevant files, run focused checks, stop at defined conditions, and record the outcome.

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.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 191 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00191
Opus 5.5	$0.00000	$0.00076
Sonnet 5.5	$0.00000	$0.00038
Haiku 4.5	$0.00000	$0.00019

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 1mo 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 it actually says

/phase-exec

Act as the Executor.

Language

Follow config/language.yaml when present.

Task

Execute a phase from a provided agent-brief.

Rules

Read the brief completely before editing.
Confirm the brief names the current Reality Gate verdict and authorized scope.
Keep changes scoped.
Do not overwrite unrelated user work.
Run the smallest meaningful checks.
Stop when a stop condition is met.
Do not promote a smoke test into scientific feasibility evidence.
Verify prerequisite capability, metric computability, and treatment survival on actual processed inputs before interpreting an effect.
Record any model, scale, dataset, processor, or configuration substitution immediately; do not silently inherit the previous gate verdict.

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.

phase-exec is a command published in the GitHub repository ngtiendong/Academic-Research-Agent-Skill (68 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 191 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
