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.

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 | $0.00000 | $0.14208 |
| Opus 5 | $0.00000 | $0.07104 |
| Sonnet 5 | $0.00000 | $0.02842 |
| Haiku 4.5 | $0.00000 | $0.01421 |
Grade A, and why
project:plan-and-do scanned grade A with 1 finding 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Bash(curl:*) How it starts
The opening of the file, as written. The whole thing — 978 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plan and Do Workflow
Branch Protection
All commits go to the NEW BRANCH created by this skill. When you start on a feature branch (not main/master) you may choose to keep it instead of creating a new one (Step 4.4) — then commits go to that branch. When the skill creates a new branch, the original branch always stays clean. State file written to disk first, committed after switching to new branch.
PR Target Rule: PRs always target original_branch — the branch that was active when the skill started. This branch is captured in Step 4.4 via git branch --show-current and stored in config.original_branch. Never default to main/master for PRs.
Non-git mode: If the project directory is not a git repository (e.g., ZIP download), all git operations (branch, commit, push, PR) are skipped. The skill still runs: state file, PRD, plan, implementation, and review all work without git.
Review scope: Code review (Step 10) compares against original_head — the starting branch's commit captured at Step 4.4 — not main/master.
PLAN MODE CHECK
If in plan mode (system reminders indicate plan mode active):
ERROR: This skill cannot run in plan mode.
Please exit plan mode and run this skill again.
STOP immediately.
If NOT in plan mode → continue.
What ships with it
2 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.

project:plan-and-do is a skill published in the GitHub repository atra-consulting/coding-with-ai-lab (5 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 14,208 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
