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 | $0.00090 | $0.01885 |
| Opus 5 | $0.00045 | $0.00942 |
| Sonnet 5 | $0.00018 | $0.00377 |
| Haiku 4.5 | $0.00009 | $0.00188 |
Grade A, and why
nx-workspace 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.
This is a copy
100% identical to nx-workspace — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nx Workspace Exploration
This skill provides read-only exploration of Nx workspaces. Use it to understand workspace structure, project configuration, available targets, and dependencies.
Keep in mind that you might have to prefix commands with npx/pnpx/yarn if nx isn't installed globally. Check the lockfile to determine the package manager in use.
Listing Projects
Use nx show projects to list projects in the workspace.
The project filtering syntax (-p/--projects) works across many Nx commands including nx run-many, nx release, nx show projects, and more. Filters support explicit names, glob patterns, tag references (e.g. tag:name), directories, and negation (e.g. !project-name).
# List all projects
nx show projects
# Filter by pattern (glob)
nx show projects --projects "apps/*"
nx show projects --projects "shared-*"
# Filter by tag
nx show projects --projects "tag:publishable"
nx show projects -p 'tag:publishable,!tag:internal'
# Filter by target (projects that have a specific target)
nx show projects --withTarget build
# Combine filters
nx show projects --type lib --withTarget test
nx show projects --affected --exclude="*-e2e"
nx show projects -p "tag:scope:client,packages/*"
# Negate patterns
nx show projects -p '!tag:private'
nx show projects -p '!*-e2e'
# Output as JSON
nx show projects --json
Project Configuration
Use nx show project <name> --json to get the full resolved configuration for a project.
Important: Do NOT read project.json directly - it only contains partial configuration. The nx show project --json command returns the full resolved config including inferred targets from plugins.
You can read the full project schema at node_modules/nx/schemas/project-schema.json to understand nx project configuration options.
# Get full project configuration
nx show project my-app --json
# Extract specific parts from the JSON
nx show project my-app --json | jq '.targets'
nx show project my-app --json | jq '.targets.build'
nx show project my-app --json | jq '.targets | keys'
# Check project metadata
nx show project my-app --json | jq '{name, root, sourceRoot, projectType, tags}'
What ships with it
1 file 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.

nx-workspace is a skill published in the GitHub repository lukascivil/json-difference (58 stars, last pushed 22d ago), licensed MIT. It adds 90 tokens to every session and 1,885 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to nx-workspace, differing in 4 lines, and is treated as a copy.
Other skills, from other repositories
task-manager
Capture actionable user requests as persistent tasks, update task status as work progresses, and keep a shared task store in sync. Use when a user asks an agent to do work, check progress, block a task, complete a task, or manage the Kanban board.
todo
Maintain a shared workspace TODO list with blocked tasks.
blazediff
Run, author, or update BlazeDiff visual regression tests. Trigger on "visual test", "screenshot regression", "blazediff", "/blazediff".
image-compare
Compare two image files on disk and report what changed, region by region. Trigger on "what changed between these two images", "diff these PNGs", "did this render drift", "compare screenshots/exports/renders".
task-manager
Capture actionable user requests as persistent tasks, update task status as work progresses, and keep a shared task store in sync. Use when a user asks an agent to do work, check progress, block a task, complete a task, or manage the Kanban board.
claim-issue
Atomically claim an issue for a developer (human or agent) via the cross-developer lock ref, so two devs never pick up the same task. Syncs with origin first, refuses if already claimed or already done on main, and pushes the claim immediately without touching main or triggering CI.
