A skill for viewing and managing SubFrame Sub-Tasks, which are project tasks stored as individual Markdown files. It covers task status, details, dependencies, notes, and completion steps.

Use it to list tasks, read task details, start or complete tasks, and create new tasks from conversation.

It keeps the project's task records synchronized with the work being discussed. It makes pending work, blockers, and completed steps easier to track.

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 Rogue Agent · line 101
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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	$0.00032	$0.00776
Opus 5.5	$0.00013	$0.00310
Sonnet 5.5	$0.00006	$0.00155
Haiku 4.5	$0.00003	$0.00078

Security

Grade A, and why

sub-tasks 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.

SubFrame Sub-Tasks

Manage the project's Sub-Task system. Sub-Tasks are SubFrame's project task tracking stored as individual markdown files in .subframe/tasks/.

Dynamic Context

Current task index: !cat .subframe/tasks.json 2>/dev/null || echo "No tasks.json found"

Instructions

Argument: $ARGUMENTS

Task File Format

Each task is a markdown file in .subframe/tasks/ with YAML frontmatter:

---
id: task-abc123
title: My task title
status: pending
priority: medium
category: feature
description: What needs to be done
userRequest: The user's original words
acceptanceCriteria: How to verify completion
blockedBy: []
blocks: []
createdAt: 2024-01-01T00:00:00.000Z

Operations

List tasks

Read .subframe/tasks.json for the index overview, or glob .subframe/tasks/*.md and read frontmatter.

Get task details

Read the specific .subframe/tasks/<id>.md file.

Start a task (pending → in_progress)

Edit the task's frontmatter: set status: in_progress and update updatedAt.

Complete a task

Edit the task's frontmatter: set status: completed, set completedAt to current ISO timestamp, update updatedAt.

Add a new task

Create a new .subframe/tasks/<id>.md file with:

Generate id: task- + 8 random alphanumeric chars
Set status: pending, createdAt and updatedAt to current ISO timestamp
completedAt: null
Include all required fields in frontmatter

Update a task

Edit the frontmatter fields as needed. Always update updatedAt.

Archive completed tasks

Move completed .md files to .subframe/tasks/archive/YYYY/ (create directory if needed).

After Any Write Operation

Regenerate the .subframe/tasks.json index by reading all .subframe/tasks/*.md files (excluding archive/) and building the JSON structure with tasks grouped by status (pending, inProgress, completed).

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.

sub-tasks is a skill published in the GitHub repository Codename-11/SubFrame (10 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 776 once invoked, about $0.0001 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.
