walkthrough

walkthrough is a skill for Claude Code from smallnest/goal-workflow. It costs 131 tokens per session (5,066 once invoked), scanned A, original, MIT.

A Markdown walkthrough document made after a code change has been implemented and checked. It explains what changed, lists verification commands and tests, includes visual evidence, and provides a final review checkpoint before merging.

In plain words
What is it for?
Documenting implementation results, unit tests, automated browser tests, screenshots or recordings, and the final Git review before a commit, pull request, or merge.
Why use it?
It gives reviewers a plain-language record of the change and evidence that it works, rather than making them infer everything from a code diff. A code diff is the list of changes between versions.

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

walkthrough 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/md2html.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 376 lines — stays where its author put it; the contents beside it link to each section on GitHub.

walkthrough — Phase 2: The Walkthrough Plan

Once the agent finishes execution and verification, it outputs a walkthrough artifact: a single Markdown file that lets you quickly catch up on what was changed and what is proven to work, and lets you do a staging-check with Git before merging.

This is modeled on Google Antigravity's walkthrough plan: the agent is expected to prove the change works (unit tests + real browser behavior), capture visual evidence, and hand you a review gate — not just dump a diff.

When to use

  • After /goal (or any implementation) plus its verification pass are complete — e.g., after /review-it / /verify / manual testing
  • Before /ship-it, as the last checkpoint before commit/PR/merge
  • User says "walkthrough", "生成 walkthrough", "生成走查文档", "write the walkthrough", "/walkthrough", "Phase 2 walkthrough"

The Job

  1. Determine the change scope — which feature / Issue / branch is being walked through, and which repos it spans
  2. Write the plain-language opening — before/after + why, readable by someone who has never seen the code
  3. Write the Change Summary — the technical detail, for whoever will read the diff next
  4. Run and record Verification Steps — execute the tests and commands, capture real output, label each claim's provenance
  5. Capture Visual Proof — screenshot / record the UI behavior you verified
  6. Build the Review Gate — stage-check the diff with Git, draft the PR description, spell out deploy-order prerequisites
  7. Save to tasks/ and present — write walkthrough-[feature].md, render it to HTML, summarize for the user

Section-by-section

1. 先说人话 / Plain-language opening (读前必读)

The first thing in the file. A PM, QA, a neighbouring team, or you in three months must be able to read only this section and know what changed and why they should care.

Required content:

  • Before / after, concretely — what the caller/user sees, not what the code does:

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.

Changes

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.

walkthrough is a skill published in the GitHub repository smallnest/goal-workflow (293 stars, last pushed 1mo ago), licensed MIT. It adds 131 tokens to every session and 5,066 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-09-14.
