archive

archive is a skill for Claude Code, Codex from SSBun/csl-agent-kit. It costs 60 tokens per session (647 once invoked), scanned A, original, MIT.

A tool for preserving an exact, visible section of a Pi conversation as a transcript.

In plain words
What is it for?
Archiving a selected range of user and agent messages when you need to keep the original wording.
Why use it?
It prevents important conversation history from being lost or replaced with an approximate summary.

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 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/archive-session.mjs), 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Archive Conversation

Save a verbatim historical transcript from the current Pi session. The command argument is a selection instruction, never transcript content.

Workflow

  1. Require a non-empty selection instruction; ask what to preserve when missing.

  2. Resolve the source boundary:

    • For /archive, use the host-provided session file, workspace, and source leaf.
    • For natural Pi invocation, use PI_SESSION_FILE, list the active branch, and exclude the current archive request.
    • Without a raw Pi session file or reliable endpoint, stop rather than reconstructing from memory or compacted context.
  3. Inspect visible messages:

    node <skill-dir>/scripts/archive-session.mjs list --session <session-file> [--leaf <source-leaf>] [--limit 200]
    

    Increase the limit only when the requested segment is older.

  4. Map the instruction to one contiguous inclusive message-ID range. A topic is sufficient only when it identifies one clear segment. If multiple ranges or endpoints are plausible, ask one focused clarification before writing.

  5. Inspect exact candidate text when needed:

    node <skill-dir>/scripts/archive-session.mjs show --session <session-file> [--leaf <source-leaf>] --from <message-id> --to <message-id>
    
  6. Derive a short title in the user's language and save:

    node <skill-dir>/scripts/archive-session.mjs save --session <session-file> [--leaf <source-leaf>] --workspace <workspace> --from <message-id> --to <message-id> --selection <original-instruction> --title <title>
    
  7. Report only the saved path and message count.

Exactness Contract

  • Preserve selected User and Agent text in branch order without summarizing, correcting, translating, escaping, or normalizing whitespace.
  • Include only text blocks from standard user and assistant messages.
  • Exclude system/developer prompts, thinking, tool calls/results, images, custom entries, compaction summaries, and abandoned branches.
  • The script owns extraction and writing; never copy transcript text manually.
  • Exclude the /archive dispatch turn unless explicitly requested.
  • V1 supports one contiguous range. For tool data or disjoint ranges, explain the boundary and ask for one supported range.

Files

What ships with it

3 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.

archive is a skill published in the GitHub repository SSBun/csl-agent-kit (10 stars, last pushed 5d ago), licensed MIT. It adds 60 tokens to every session and 647 once invoked, about $0.0003 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 2026-08-31.
