What is exec-plan-runner?

An automated workflow for carrying an issue or ExecPlan through preparation, implementation, scope checks, verification, self-review, pushing changes, and opening a pull request. An ExecPlan is a written plan for completing a development task.

It is for running issues or ExecPlans from start to pull request with commands such as /run-issue, /run-plan, and /finish-task.

It removes the need to wait for a person between each stage of a planned task while still checking the work before review.

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	$0.00168	$0.08942
Opus 5.5	$0.00067	$0.03577
Sonnet 5.5	$0.00034	$0.01788
Haiku 4.5	$0.00017	$0.00894

Measured today against content hash 4648ff6e0bd1, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

exec-plan-runner 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 today.

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.

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.
