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 | $0.00012 | $0.00841 |
| Opus 5 | $0.00006 | $0.00420 |
| Sonnet 5 | $0.00002 | $0.00168 |
| Haiku 4.5 | $0.00001 | $0.00084 |
Grade A, and why
version-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 2d 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.
What it actually says
Analyze all changes in the current branch (including committed, uncommitted, staged, and unstaged changes) compared to origin/main and generate one or more Nx version plan files as needed.
First, determine the current branch and find all changes compared to origin/main:
- Check the current branch with
git branch --show-current - If on
mainbranch, compare againstorigin/mainto include unpushed commits:- Get unpushed commits:
git log --oneline origin/main..HEAD - Get the full diff:
git diff origin/main..HEAD - Also check for any uncommitted changes:
git statusandgit diff
- Get unpushed commits:
- If on a feature branch:
- Find the merge base:
git merge-base HEAD origin/main - Get all commits in the branch:
git log --oneline <merge-base>..HEAD - Get the full diff of all changes:
git diff <merge-base>..HEAD - Also check for any uncommitted changes:
git statusandgit diff
- Find the merge base:
If there are no changes at all (neither in commits nor uncommitted), inform the user that no version plan is needed.
Then, check existing version plans in .nx/version-plans/ to ensure you're not creating duplicate or similar plans.
Analyze the changes to determine if they should be grouped into one or multiple version plans:
- Group related changes together (e.g., all changes for a single feature)
- Create separate plans for unrelated changes (e.g., a bug fix and a new feature)
- Consider the scope and impact of changes when deciding how to group them
For each version plan needed:
- Determine the appropriate semantic version bump:
- patch: Bug fixes, typo corrections, documentation changes, internal refactors that don't affect functionality
- minor: New features, enhancements, non-breaking improvements
- major: Breaking changes, API modifications, removal of features
- Create a concise, single-line changelog entry
- Generate a descriptive filename (using kebab-case)
Create the version plan file(s) in .nx/version-plans/ for each distinct change or group of related changes.
The file format should be:
---
__default__: version-type
---
Single line changelog entry describing the changes
Examples:
-
Bug fix (patch):
- Filename:
fix-memory-leak-in-parser.md - Content:
--- __default__: patch --- Fix memory leak in parser when handling large files - Filename:
-
New feature (minor):
- Filename:
add-authentication-feature.md - Content:
--- __default__: minor --- Add authentication feature with OAuth support - Filename:
-
Breaking change (major):
- Filename:
remove-deprecated-api-methods.md - Content:
--- __default__: major --- Remove deprecated API methods from v1.x - Filename:
Important:
- Always use
__default__since this repository releases the same version for all projects - The changelog entry must be a single line without bullet points or multiple paragraphs
- Create separate version plans for unrelated changes (don't combine a bug fix with a new feature)
- Each filename should be descriptive, unique, and clearly indicate what changed
- Avoid creating plans for changes that already have similar plans in the directory
- Consider creating multiple plans when:
- Changes affect different areas of the codebase
- Changes have different semantic version impacts
- Changes represent distinct features or fixes
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.

version-plan is a command published in the GitHub repository phuctm97/modelfetch (145 stars, last pushed 8mo ago), licensed MIT. It adds 12 tokens to every session and 841 once invoked, about $0.0001 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 2026-08-30.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
