context-management

context-management is a skill for Claude Code from OneDro1d/dark-factory. It costs 75 tokens per session (522 once invoked), scanned A, original, Apache-2.0.

A skill for maintaining the project’s shared record of services, data flows, known bugs, and architecture decisions. It keeps that record brief, sourced, and reusable.

In plain words
What is it for?
Use it to record a confirmed root cause, architecture decision, service or contract change, or to compress and correct project context.
Why use it?
It prevents future agents and developers from repeating the same investigation or relying on stale notes. Confirmed facts, decisions, and service changes remain connected to their source.

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

context-management 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 8d 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

Context Management (analyze once, reuse forever)

Goal: keep .claude/context/ the single, terse, trustworthy memory so agents never re-scan the repo to re-learn what's known. This is the main token-saving lever.

The store

  • SERVICE-MAP.md — components + flows (one line each).
  • FINDINGS.md — confirmed bugs/root causes (append-only ledger, status-tagged).
  • DECISIONS.md — architecture decisions/rulings (ADR log).
  • <service>/CLAUDE.md — deep per-service detail.
  • shared-models CLAUDE.md — contract index.

When to write

  • Confirmed root cause → new F-### in FINDINGS.md (symptom, cause, file:line, status). So it's never re-investigated.
  • Design/architecture decision → new D-### in DECISIONS.md (decision, why, source).
  • New/changed service, routing key, table, object-store key → update SERVICE-MAP.md + the service CLAUDE.md + (if a contract) the shared-models index.
  • Status change (OPEN→FIXED) → update the existing entry, don't duplicate.

How to write (compression rules)

  • One fact per entry. Cite a source (file:line, ruling, ticket) for every claim — no guessing.
  • Prefer tables/IDs over prose. Replace, don't append, when a fact changes.
  • If notes have grown long, distill to the durable fact and delete the scratch.
  • Keep each context file roughly a screen — if it's growing, compress.

Read-first reminder for every agent

SERVICE-MAP → FINDINGS → DECISIONS → the one relevant CLAUDE.md → source. Stop as soon as you have enough.

Don't

  • Don't record session chatter or anything the code/git already states.
  • Don't let the store drift from code — if you find a stale entry, fix it (cite the code).

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.
