archive

archive is a skill for Claude Code, Codex from bks-lab/open-bridge. It costs 90 tokens per session (538 once invoked), scanned A, original, MIT.

A periodic workflow for collecting work logs, summarising a completed period, saving proposed lasting facts to a memory store, and resetting the period log.

In plain words
What is it for?
Archiving weekly, bi-weekly, monthly, quarterly, or yearly periods; proposing memories for confirmation; resetting log.md; and checking upstream changes.
Why use it?
It turns old work notes into reusable knowledge while preserving an archive and keeping the active log manageable.

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 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.

What it actually says

Archive

Periodic archive workflow. Read the referenced file ONLY when triggered.

The period is configurablebridge-config.yaml work.archive_cadence (weekly default, then bi-weekly / monthly / quarterly / yearly). The same key drives /briefing's staleness warning, so the reminder and the archiver always agree on what "overdue" means.

Archiving distils before it resets: work/archive/ has no reader, so without a distil step archiving would be forgetting with a backup. Phase 5 proposes durable facts for the memory base — which is loaded every session — and never writes one without confirmation (rules/learning-autonomy.md).

Arguments

Argument Effect Default
(none) Archive the oldest closed period, per work.archive_cadence
--force Archive the current (in-progress) period too false
--no-distil Skip Phase 5; archive without proposing memories false

Prerequisites

bridge-config.yaml with work.enabled: true. If not: inform and exit.

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.
