proactive-agent

proactive-agent is a skill for Claude Code, Codex from 1mancompany/OneManCompany. It costs 50 tokens per session (3,941 once invoked), scanned A, original, Apache-2.0.

A set of practices for making an AI agent proactive, persistent, searchable, and safer. It includes ways to preserve important context when a conversation is shortened and to recover afterward.

In plain words
What is it for?
Use it to guide proactive check-ins, suggestions, context logging, recovery after context limits, skill-installation checks, network warnings, and protection against leaking context.
Why use it?
It helps an agent retain decisions and corrections, find information across available sources, and handle context loss or security risks more carefully.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium System Prompt Leakage · line 34
    Skill contains patterns that could indirectly extract system prompts through rephrasing, translation, summarization, or side-channel techniques.
    Fix: Guard against indirect extraction by refusing to summarize, translate, or rephrase system instructions. Add explicit anti-extraction clauses.

  • medium Excessive Agency · line 292
    Skill grants unrestricted tool access without appropriate constraints. An agent with unfettered tool access can perform arbitrary actions including file modification, network requests, and code execution.
    Fix: Restrict tool access to only the tools required for the skill's stated purpose. Use an explicit allowlist rather than granting blanket access.
  • medium Excessive Agency · line 385
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

proactive-agent scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Proactive Agent 🦞

By Hal Labs — Part of the Hal Stack

A proactive, self-improving architecture for your AI agent.

Most agents just wait. This one anticipates your needs — and gets better at it over time.

What's New in v3.0.0

  • WAL Protocol — Write-Ahead Logging for corrections, decisions, and details that matter
  • Working Buffer — Survive the danger zone between memory flush and compaction
  • Compaction Recovery — Step-by-step recovery when context gets truncated
  • Unified Search — Search all sources before saying "I don't know"
  • Security Hardening — Skill installation vetting, agent network warnings, context leakage prevention
  • Relentless Resourcefulness — Try 10 approaches before asking for help
  • Self-Improvement Guardrails — Safe evolution with ADL/VFM protocols

The Three Pillars

Proactive — creates value without being asked

Anticipates your needs — Asks "what would help my human?" instead of waiting

Reverse prompting — Surfaces ideas you didn't know to ask for

Proactive check-ins — Monitors what matters and reaches out when needed

Persistent — survives context loss

WAL Protocol — Writes critical details BEFORE responding

Working Buffer — Captures every exchange in the danger zone

Compaction Recovery — Knows exactly how to recover after context loss

Self-improving — gets better at serving you

Self-healing — Fixes its own issues so it can focus on yours

Relentless resourcefulness — Tries 10 approaches before giving up

Safe evolution — Guardrails prevent drift and complexity creep

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.

proactive-agent is a skill published in the GitHub repository 1mancompany/OneManCompany (414 stars, last pushed 14d ago), licensed Apache-2.0. It adds 50 tokens to every session and 3,941 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
