go

go is a skill for Claude Code from napalmpapalam/skills. It costs 111 tokens per session (3,072 once invoked), scanned A, original, MIT.

A guided way to plan and build a feature in small, complete slices. Each slice goes through the layers it needs, compiles and runs, and is intended to be one reviewable pull request.

In plain words
What is it for?
Use it to break a new feature or project into working increments, plan the next slice, or continue development from an existing plan.
Why use it?
It keeps large features from becoming one risky, difficult-to-review change. A living document carries the plan and lessons from one slice to the next.

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

go 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 9d 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Go

Plan and ship a feature as vertical slices driven by one living doc — one slice ("a go") at a time. This encodes a fixed method so it never has to be re-explained per feature.

The method is depth-first and just-in-time: build one complete, working layer at a time, fold what you learned back into the doc, then the user clears the chat and starts the next slice from that doc.

Principles (non-negotiable)

  • Every slice compiles and runs. A slice is a complete thin path through all the layers it touches — never a horizontal spec fragment. After each slice the project is green: it builds, runs, and the new behavior works.
  • A slice is one reviewable PR. Target ≤1000 lines changed, hard cap 1500, lock files excluded. A big feature is several slices, each mergeable on its own, so cross-review stays sane.
  • No dead code. Build only what this slice needs. No config, interface, or scaffold for a future slice that hasn't arrived. If it isn't used now, it isn't in scope.
  • One slice per session. Planning and building are separate sessions too — a new doc is handed over, not built on (Step 2.5). After a slice lands, the user runs /clear and starts the next one fresh from the doc. Don't try to do two slices in one go.
  • What before how. The user often knows the end state, not the path. Settle how the slice will work before writing code (see Step 1).
  • Slices are scaffolding, not vocabulary. "Slice", "go", slice numbers, and the doc itself are your planning frame — they mean nothing to anyone reading the repo. Never let them leak into commit messages, PR titles or descriptions, source comments, doc comments, READMEs, identifiers, or test names. Describe the change by what it does, not by where it sat in the plan.
    • feat: slice 2 — transcript loading · ✅ feat(transcript): load a session JSONL into scrollable lines
    • /// Reading measure, in columns. Configurable in slice 4. · ✅ /// Reading measure, in columns. — a not-yet-built option is not a fact about the code; if the constraint is real, say it without the slice number.
    • ❌ a PR description opening "This is the second go on the quotr doc." · ✅ open with what the PR changes and why.

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.
