aio-plan

aio-plan is a skill for Claude Code, Codex from aiocean/claude-plugins. It costs 42 tokens per session (1,125 once invoked), scanned A, original, MIT.

A planning step that turns project discovery and dependency mapping into a step-by-step implementation plan. It belongs to a workflow that follows aio-discover and aio-map.

In plain words
What is it for?
Use it after discovery and dependency mapping when you need to decide what implementation work should happen and in what order.
Why use it?
It helps turn gathered information into an ordered plan before coding begins.

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

aio-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 4d 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.

Plan — Implementation Planning

Environment

  • GitNexus: !npx gitnexus status 2>/dev/null && echo "AVAILABLE" || echo "NOT INSTALLED"

Synthesize discovery and mapping results into a concrete, actionable implementation plan.

Prerequisites

  • Run /discover and /map first (or have equivalent understanding)
  • GitNexus indexed (npx gitnexus analyze) for convention/duplication checks

Workflow

Step 1: Duplication check (GitNexus)

Search if similar features already exist using the GitNexus MCP query tool:

query("similar feature or pattern")

Prevents building what already exists.

Step 2: Convention check (GitNexus)

Search for existing patterns to follow:

query("how are [similar things] implemented")

Examples: "tauri command structure", "hook cleanup pattern", "error handling in rust"

Step 3: Context enrichment (GitNexus)

For each file you plan to modify, get full context:

context(file)

This reveals dependencies, dependents, and all symbols — helps identify:

  • Functions that will be affected by your changes
  • Files that import the file you're changing (blast radius)
  • Existing symbols you can reuse instead of creating new ones

For the most critical change, check impact:

impact(file)

Step 4: Write the plan

## Plan: [Feature/Fix Name]

### Goal
[One sentence: what and why]

### Discovery Summary
[Key findings from /discover]

### Approach
[High-level strategy: which layer handles what]

### Changes

#### 1. `file path` — [what changes]
- [ ] Add/modify function `X` to do Y
- [ ] Update type `Z`
- Reason: [why this file]

#### 2. `file path` — [what changes]
- [ ] ...

### Risks
- **[Risk]**: [Mitigation]

### Convention Check
- Follows: [existing pattern found]
- Deviates: [if any, with justification]

### NOT Doing
[Explicitly list out-of-scope items]

Step 5: Create baseline

Run /aio-snapshot before starting implementation.

Step 6: Execution handoff

After the plan is approved, choose an execution strategy:

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.

aio-plan is a skill published in the GitHub repository aiocean/claude-plugins (4 stars, last pushed yesterday), licensed MIT. It adds 42 tokens to every session and 1,125 once invoked, about $0.0002 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.
