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.

SkillSpector: 1 finding, up to high
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 →
- high Memory Poisoning · line 370 Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.
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 | $0.00110 | $0.03175 |
| Opus 5 | $0.00055 | $0.01588 |
| Sonnet 5 | $0.00022 | $0.00635 |
| Haiku 4.5 | $0.00011 | $0.00317 |
Grade A, and why
gtd-coach 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 12d 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.

GTD Coach - Personal Goal Achievement System
Overview
This skill transforms annual goals or detailed plans into an actionable, trackable execution system. It provides daily guidance, task management, progress tracking, and regular reviews to ensure users achieve their objectives.
Key Features:
- Converts goals into structured SOPs with timelines
- Generates daily prioritized task lists
- Breaks down tasks into specific steps
- Tracks progress across conversations using memory
- Triggers appropriate reviews (daily/weekly/monthly/quarterly)
- Adapts plans based on progress and feedback
Memory Integration
This skill uses Claude's memory system to persist user data across conversations. This enables:
- No repeated input: User sets goal once, Claude remembers
- Progress continuity: Each conversation picks up where the last ended
- Automatic updates: Progress is saved at end of each session
Memory Structure
Claude stores the following in memory:
GTD Goal: [One-line goal statement]
GTD Target Date: [YYYY-MM-DD]
GTD Current Phase: [Q1-Validate/Q2-Scale/Q3-Systematize/Q4-Achieve]
GTD Progress: [X]% toward goal
GTD Last Session: [YYYY-MM-DD]
GTD Language: [English/中文/日本語]
GTD Weekly Status: [Week X - X/Y tasks completed]
GTD Key Metrics: [metric1:value, metric2:value]
GTD Active Tasks: [task1|status, task2|status]
GTD Blockers: [blocker1, blocker2]
Memory Operations
On First Use (Goal Setup):
- Guide user through goal definition
- Save goal framework to memory using
memory_user_editstool - Generate initial SOP and timeline
On Subsequent Sessions:
- Check memory for existing goal data
- Calculate current date position in timeline
- Generate today's tasks based on progress
- Resume from last session's state
On Session End:
- Summarize completed tasks
- Update progress percentage in memory
- Record any blockers or adjustments
- Save updated state for next session

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gtd-coach is a skill published in the GitHub repository iamzifei/gtd-coach-plugin (39 stars, last pushed 10d ago), licensed MIT. It adds 110 tokens to every session and 3,175 once invoked, about $0.0006 per session on Opus 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 2026-08-30.
