fold: Skill for Claude Code

.claude/skills/roadmap/SKILL.md

roadmap is a skill for Claude Code from fold-run/fold. It costs 75 tokens per session (1,122 once invoked), scanned A, original, Apache-2.0.

A set of instructions for handling dependency and security-vulnerability work in the fold project, a Go software project. It covers vulnerability scans, Dependabot update requests, and upgrades to the MCP software-development kit or Go toolchain.

In plain words
What is it for?
Use it when vulnerability checks fail, CI reports a security issue, a Dependabot request needs review, or a project dependency or Go version must be updated.
Why use it?
It helps distinguish whether a failing security check comes from a code change, a newly published advisory, or an automated update process.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

This is fold-run/fold's own configuration. It tells Claude Code how to work on fold itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything fold configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go test ./internal/doclint # every Markdown link and anchor resolves.

Reuse

Borrowing it

Nothing to install: this file belongs to fold-run/fold. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Copy the file
curl -O https://raw.githubusercontent.com/fold-run/fold/main/.claude/skills/roadmap/SKILL.md
Clone the repo
git clone --depth 1 https://github.com/fold-run/fold

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

roadmap 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 2mo 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The gap list and the roadmap

These are not marketing documents. gateway/era_test.go and gateway/listen_test.go fail with messages that point the reader at them, and CLAUDE.md's fourth rule makes updating them a merge condition. A gap here is load-bearing text.

Two surfaces, different jobs:

  • README "Not implemented" — what fold does not do today, with the reason. Read by someone evaluating fold, so each entry has to survive a skeptic: name the gap, name the cause (structural, waiting on someone else, or deliberate), and say what would close it.
  • docs/roadmap.md — what fold intends, in three horizons plus "Non-goals" and "Deprecations on the clock". No dates, deliberately.

Every "Not implemented" entry has a roadmap counterpart. The README says what is missing; the roadmap says whether it is coming.

The four vetoes

docs/roadmap.md "How to read this" names what kills an item regardless of demand:

  1. the v1 compatibility contract and the frozen defaults,
  2. the invisibility rule,
  3. the added-latency gate,
  4. audit as the single exit door.

A feature that requires breaking one does not get built — it gets a non-goal entry with the reasoning written down. That conversion is the main judgement this skill exists for. Content inspection is the worked example: it is a non-goal because inspecting bodies means buffering and rewriting, which conflicts with (2) and (3) — and the entry still offers the fold-shaped answer (the decision hook) rather than stopping at "no".

A non-goal entry that only says no is incomplete. Say what the veto was and what someone with that need should do instead.

Closing a gap

When a change closes one, the same PR does all of it:

  • Remove or narrow the README "Not implemented" entry — narrowing is common and honest: three consequences, one addressed, two named.
  • Update the roadmap counterpart (move it out of its horizon, or strike it).
  • Find the canary. If the gap was waiting on someone else, there is probably a test that fails when the wait ends. Flip or delete it, and never "fix" one by loosening the assertion.
  • CHANGELOG entry if it ships in a release.

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.
