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 | $0.00095 | $0.03063 |
| Opus 5 | $0.00048 | $0.01532 |
| Sonnet 5 | $0.00019 | $0.00613 |
| Haiku 4.5 | $0.00010 | $0.00306 |
Grade A, and why
agent-development 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 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.
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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
6 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.

agent-development is a skill published in the GitHub repository proxify-dev/agentic-playbook (2 stars, last pushed 9d ago), with no licence file. It adds 95 tokens to every session and 3,063 once invoked, about $0.0005 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 2026-08-31.
Other skills, from other repositories
project-context
Create and commit a current-work Handoff when the user says "交接", "交接当前工作", "handoff this work", or equivalent; also restore project memory and continue prior work through PowerContext.
aidd-dev:00:sdlc
Pure orchestrator for the full AIDD development flow. Use when a human (or Gardener) needs to take a free-form request from idea to shipped code, end-to-end. Coordinates spec generation, planning, implementation, and review by composing other skills and agents. Holds no business logic of its own — every step is…
aidd-pm:05:spec
Generates and refines a project spec from a free-form human request. The spec is the immutable target a planner consumes. Use when starting a new run, when an existing spec needs refinement after review, or when a human wants to draft a spec collaboratively.
aidd-context:02:project-init
Initialize or refresh the project memory bank, scaffold the rules directory, and ensure AI context files contain the project memory block. Use when running aidd init for the first time, bootstrapping a new project, or re-running the init flow on an existing project. Do NOT use for updating individual memory files…
aidd-dev:08:for-sure
Iterative agent loop that tracks attempts and retries until a success condition is met. Use when the user says "for sure", "make sure", "keep trying until", "loop until done", "don't stop until", or needs guaranteed completion of a task with explicit success criteria.
