sr:plan is a skill for Claude Code from huuanh20/awesome-ai-agent-skills. It costs 52 tokens per session (1,150 once invoked), scanned A, original, MIT.

A planning role in a software requirements workflow. It reads a software specification and creates detailed blueprints for each major section.

In plain words
What is it for?
Use it to plan requirements, interfaces, functional behavior, performance needs, actors, assumptions, and related software details.
Why use it?
It breaks a large specification into concrete planning documents that developers can follow.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool; installed under .agents/ (shared by several agents).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python .claude/scripts/plan_validator.py --dir projects/{slug}/plan/ --stats.

Good fit Use it to plan requirements, interfaces, functional behavior, performance needs, actors, assumptions, and related software details.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

sr:plan 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.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sr:plan

Goal: produce 12 plan files — one per SRS section — that serve as unambiguous blueprints for SRS generation. No summarizing, no truncation.


Step 0 — Identify Project

AskUserQuestion: "Which project to plan? (slug)"

Read projects/{slug}/spec.md. If missing, tell user to run /sr:spec first. Load .claude/skills/srs-workflow/references/plan-structure-guide.md.


Step 1 — Write Plan Files

Create all files under projects/{slug}/plan/. For each file, follow the detailed spec in plan-structure-guide.md for what must be included.

Write in this order (each file before proceeding to next):

  1. 00-overview.md — master map, FR/NFR count totals, actor table, assumptions
  2. 01-introduction.md — §1.1 Purpose, §1.2 Scope (IN/OUT table), §1.3 Definitions, §1.4 References, §1.5 Overview
  3. 02-overall-description.md — §2.1 Perspective, §2.2 Functions, §2.3 User Characteristics, §2.4 Constraints, §2.5 Assumptions, §2.6 Apportioning
  4. 03-01-external-interfaces.md — UI screens, hardware, software APIs, communication protocols
  5. 03-02-functional-requirements.md — ALL FRs with "shall" stubs + GWT stubs + priority
  6. 03-03-performance.md — ALL NFRs with numeric Response Measure or [TBD]
  7. 03-04-database.md — entities, retention, volumes, PII fields
  8. 03-05-design-constraints.md — imposed tech stack, compliance-driven constraints
  9. 03-06-system-attributes.md — reliability, availability, security, maintainability, portability, usability
  10. 03-07-other-requirements.md — i18n, legal, operational, transition, training
  11. appendix-a-glossary.md — all domain terms needing precise definitions
  12. appendix-b-open-issues.md — every [NEEDS USER INPUT] from all plan files, with owner + resolve-by

FR numbering rules (enforced across all plan files):

  • Sequential: FR-01, FR-02, FR-03 … no resets between sections
  • Format: FR-NN [Essential|Conditional|Optional]
  • Every FR must have: Requirement (shall clause) + Given/When/Then stubs
  • Tag unclear items: [NEEDS USER INPUT: {specific question}]

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.
