context-agent

A session-memory helper that saves summaries, decisions, unfinished tasks, errors, changed files, and technical findings for later sessions.

In plain words
What is it for?
Use it to save context at the end of a session and load a briefing with the relevant history at the start of the next one.
Why use it?
It reduces the need to reconstruct previous work when a new coding session begins.

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-agent 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 2d 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.

  • When the user mentions "resumo sessao" or related topics
  • When the user mentions "continuidade sessao" or related topics

Do Not Use This Skill When

  • The task is unrelated to context agent
  • A simpler, more specific tool can handle the request
  • The user needs general-purpose assistance without domain expertise

How It Works

Continuidade perfeita entre sessões do Claude Code. Captura, comprime e restaura contexto automaticamente — tópicos, decisões, tarefas, erros, arquivos modificados e descobertas técnicas.

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.
