archive-legacy-docs

archive-legacy-docs is a skill for Claude Code, Codex from DasDigitaleMomentum/opencode-processing-skills. It costs 38 tokens per session (1,166 once invoked), scanned A, original, MIT.

A repository cleanup method for collecting scattered or historical documentation in one `docs-legacy/` archive and creating an index of what was moved.

In plain words
What is it for?
Use it when onboarding an older codebase to archive legacy documents, preserve them as reference, and prepare clean `docs/` and `plans/` directories.
Why use it?
It separates old reference material from the current documentation and planning files before new repository guidance is created.

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

archive-legacy-docs 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 5d 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.

Skill: Archive Legacy Docs

This skill prepares a clean, defined repository state before running generate-docs / create-plan on legacy repositories.

It collects existing documentation artifacts that are scattered/historical, moves them into a single archive directory docs-legacy/, and generates a lightweight index docs-legacy/summary.md.

The archived content is intended to be forensic reference, not canonical documentation.


When to Use

Use this skill when:

  • You are onboarding a legacy repo and documentation/plan artifacts are scattered.
  • You want docs/ and plans/ to start from a clean slate.

Do not use this skill when:

  • docs/ and plans/ already follow this framework’s conventions and should be preserved.

Routing Matrix (Who does what)

  • Writes: docs-legacy/** (including docs-legacy/summary.md).
  • Moves: legacy doc files from anywhere in the repo into docs-legacy/.
  • Primary: chooses/approves inclusion & exclusion policy (what counts as legacy docs).
  • legacy-curator (subagent): performs git-aware moves and writes the summary.
  • doc-explorer / implementer: not used.

Execution Model

Key semantics

  • git-aware moves:
    • If a file is tracked by git, move it with git mv.
    • If a file is untracked, move it with filesystem move.
  • flat archive:
    • All archived files end up directly under docs-legacy/ (no path-preserving).
    • Name conflicts are resolved by prefixing with the inferred module and adding a stable disambiguator.

Module inference (draft)

For each legacy document, infer a "module origin" label (best-effort):

  1. If path contains a top-level module directory (e.g. backend/, frontend/, services/<name>/, packages/<name>/), use that.
  2. Else use the first directory segment (<topdir>).
  3. Else use root.

Workflow

0) Primary inputs

Primary should provide:

  • inclusion patterns (defaults suggested below)
  • exclusion patterns (defaults suggested below)
  • whether to treat existing docs/ and plans/ as legacy (default: yes unless they match this framework)

What ships with it

2 files 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.
