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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01361 |
| Opus 5 | $0.00018 | $0.00681 |
| Sonnet 5 | $0.00007 | $0.00272 |
| Haiku 4.5 | $0.00004 | $0.00136 |
Grade A, and why
rudder-import-and-evolve 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 — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Import and Evolve Workflow
This skill teaches how to import existing RudderStack resources into CLI management and safely evolve your tracking schema over time.
When to Use This Skill
- You have existing tracking plans, events, or properties in RudderStack
- You want to manage them via YAML files and git
- You need to make changes without breaking production SDKs
- You're migrating from UI-based management to CLI

Step 1: Authenticate
rudder-cli auth login
Select your workspace when prompted.
Step 2: Verify Connection
rudder-cli workspace info
Should show your workspace name and ID.
Step 3: Import Resources
rudder-cli import workspace
This imports:
- Events
- Properties
- Categories
- Custom types
- Tracking plans
- Event stream sources (if applicable)
- Transformations and libraries
Step 4: Review Imported Files

│ ├── events/

│ ├── properties/
│ │ └── *.yaml
│ ├── categories/
│ │ └── *.yaml
│ └── custom-types/
│ └── *.yaml
└── tracking-plans/
└── *.yaml
Each file includes import metadata:
version: "rudder/v1"
kind: "event"
metadata:
name: "events"
import:
id: "evt_abc123xyz" # Links to workspace resource
workspace: "ws_xyz789"
spec:
name: "Product Viewed"
# ... rest of spec
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.

rudder-import-and-evolve is a skill published in the GitHub repository rudderlabs/rudder-agent-skills (18 stars, last pushed 7d ago), licensed MIT. It adds 37 tokens to every session and 1,361 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 2026-08-30.
Other skills, from other repositories
branch-and-worktree-workflow
Isolates feature work in its own branch or worktree and integrates it cleanly when done. Use this when starting work that should not disturb the current workspace, when several efforts must proceed in parallel on one repository, or when implementation is finished and the change needs merging, rebasing, or splitting…
pdlc-ship
A software release workflow that runs tests, updates the version and change log, creates a Git tag, and starts CI/CD, the automated build and deployment process.
iterate
Diverge-converge workflow: spin up N agents on isolated worktrees, each exploring a different approach to the same problem. Compare results side-by-side (with optional preview ports), pick a winner, merge it back. Use when the user says /iterate, 'try multiple approaches', 'explore different directions', or wants to…
pdlc-changelog
A changelog updater that reads recent Git commits and records user-facing changes in a service or application’s CHANGELOG.md. A changelog is a history of additions, fixes, and other notable changes.
chunk-pr
Analyzes a large pull request (or branch, or commit range) and proposes a sequence of smaller, logically-grouped, merge-safe PRs following review best practices — dependency first, one concern per PR, mergeable in order. Suggests a plan; the user approves. On approval, creates chunk branches, cherry-picks commits…
repo-timeline
Analyzes a repository or branch and generates a meaningful, engineer-friendly timeline of changes — grouping commits into logical units with short and detailed descriptions, using git history, changelogs, GitHub PRs, and Linear tickets. Use when you want to understand what changed, when, and why in a codebase.
