A skill that delegates a project task to a child coding-agent process and supervises its work. It uses task files, progress records, status data, and review records to track the run.

Use it to launch, monitor, and review a delegated coding task, including its plan, progress, evidence, and final outputs.

It gives longer or substantial tasks a repeatable workflow with visible progress and review checkpoints. It also encourages checking whether configuration or simplification can solve the problem before adding code.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Agent Snooping · line 1146
Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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	$0.00073	$0.16588
Opus 5.5	$0.00029	$0.06635
Sonnet 5.5	$0.00015	$0.03318
Haiku 4.5	$0.00007	$0.01659

Security

Grade A, and why

task-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 18d ago.

The scan reads SKILL.md. This mod also ships 29 executable files (scripts/__init__.py, scripts/application_adapter.py, scripts/dev_pipeline_adapter.py, …), 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 — 1,182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Current review policy

Pre-author statement review accepts an explicitly configured isolated_same_provider assurance through the existing prepared-assurance seam. Such a reviewer must have read-only access and no repository write grant. Product statement validation accepts that admitted strategy. Unconfigured Codex↔Claude pairing remains unchanged.

Task Runner

This skill launches a child CLI agent to execute a task from its task directory.

Use the standard single-child workflow by default. Use the dev-pipeline workflow when a task should run through the evidence-gated dev-pipeline lifecycle instead.

Before implementation, use the canonical no-code-first order: do nothing; remove or disable; configure or reuse; simplify; only then add the smallest necessary code and state why the observed gap required it. Independent review treats avoidable code or needless complexity as a defect.

Artifacts

The runner expects:

task.md
plan.md

It creates or updates:

trace.md
status.json
.runner/prompt.txt
.runner/runner.json
.runner/runner.log
.runner/review-admission.json for the current launch, .runner/review-admission-commitment.json while a committed binding is waiting for its author to start, and reviews/admissions.jsonl for every admission this number has made
reviews/rounds.jsonl and reviews/infrastructure-obligations.jsonl, once a review round or a review outage happens

The child is asked to publish progress.json for long runs, and to place explicitly requested output files in deliverables/ with deliverables/manifest.json.

.runner/prompt.txt is also the readable record of what the child or reviewer was told. It names one target repository as its path and multiple repositories as a comma-separated path list, never as a Python Path or list representation; a repository-less author prompt omits that line.

The dev-pipeline workflow also creates dev-pipeline/.

An application that already supervises the entire worker service or container may use start --foreground and review --foreground. These forms keep the same admission, binding, phases, review rounds and completion decision, but wait for the child in the caller process instead of detaching a watcher that the outer container would terminate. The recorded supervision durability is caller_owned; foreground never supplies a missing assurance strategy or reviewer. Once the durable pending launch claim exists, foreground supervision releases the preparation ownership lock just as a detached launch does; live process identity and the pending claim continue to refuse concurrent starts.

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.

task-runner is a skill published in the GitHub repository rdudov/task-agent (4 stars, last pushed 7d ago), licensed MIT. It adds 73 tokens to every session and 16,588 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
