ai-sdlc-workflow: Skill for Cursor

.cursor/skills/skill-updater/SKILL.md

skill-updater is a skill for Cursor from phuoctrung-ppt/ai-sdlc-workflow. It costs 21 tokens per session (251 once invoked), scanned A, original, MIT.

A skill for reviewing past project work and proposing updates to the project's instructions or reusable patterns. It looks for recurring problems in retrospectives, decisions, notes, and reviews.

In plain words
What is it for?
It helps scan project memory, identify repeated causes or patterns, and create a pending proposal for a minimal skill or pattern update.
Why use it?
It helps turn repeated lessons into documented guidance without changing the instructions automatically.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is phuoctrung-ppt/ai-sdlc-workflow's own configuration. It tells Cursor how to work on ai-sdlc-workflow itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-sdlc-workflow configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 .cursor/scripts/learning-counter.py get.

Reuse

Borrowing it

Nothing to install: this file belongs to phuoctrung-ppt/ai-sdlc-workflow. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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.

Security

Grade A, and why

skill-updater 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 8d 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.

Skill Updater

Counter (CLI only)

Propose, don't apply. Minimal patch. Update docs/memory/* when durable.

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.
