make_plan

A planning tool that creates a folder of documents describing a software feature before coding starts.

In plain words
What is it for?
Use it to plan a feature or task that needs detailed requirements, multiple technical components, and a defined testing approach.
Why use it?
It turns an unclear request into recorded requirements, an analysis of the existing code, technical details, tests, and an execution checklist.

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

make_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 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.

How it starts

The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implementation Plan Creation (make_plan)

Create a detailed, multi-document implementation plan for a software feature or task. This skill covers plan creation only. To execute a finished plan, use the exec_plan skill.

CodeOps Skills Version: 3.20.0

What you produce

A folder plans/<feature-name>/ containing:

plans/<feature-name>/
├── 00-ambiguity-register.md   # Zero-Ambiguity Gate register (audit trail)
├── 00-index.md                # Overview and navigation
├── 01-requirements.md         # Requirements and scope
├── 02-current-state.md        # Current implementation analysis
├── 03-XX-<component>.md       # Technical spec per component (one or more)
├── 07-testing-strategy.md     # Spec test cases + verification
└── 99-execution-plan.md       # Phases, sessions, task checklist

The full templates for every document live in templates.md — read it before writing any plan document in Phase 2.

Resolve paths first (layout-aware)

Determine the layout via ../../_shared/layout-convention.md before creating the plan folder:

  • Flat layout (no marker): the plan folder is plans/<feature-name>/; 00-index.md declares > **Implements**: RD-NN — exactly as flat layout always has.
  • Nested layout (marker present): the plan folder is codeops/features/<f>/plans/<plan>/. Ask/confirm the target feature first (create the feature folder lazily if new — never guess). 00-index.md declares a feature-qualified > **Implements**: <feature>/RD-NN, and any > **Source** link points at the feature's own requirements/ dir. Everywhere below that says plans/<feature-name>/ means this nested plan path.

Lightweight tasks (mini-plan path — both layouts)

Not every change is a feature. Ad-hoc work (a bugfix, chore, small change) is a task (T-NN), and a non-trivial task gets a single mini-plan, not the full multi-document set. When the work is a task (see the routing rule in ../../_shared/layout-convention.md):

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.

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.

make_plan is a skill published in the GitHub repository blendsdk/claude-codeops (4 stars, last pushed 1mo ago), licensed MIT. It adds 126 tokens to every session and 3,964 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 2026-08-31.
