What autonomous-agents does

This skill covers the agent that breaks a goal into steps, calls tools on its own and corrects itself when something breaks. Inside are ReAct and plan-execute loops, goal decomposition, reflection patterns and a section on production reliability. The full procedure lives in references/detailed-guide.md, and the skill asks you to read it before running anything, with its safety and validation rules treated as binding.

The part worth remembering is error math. At 95% per step, ten independent steps leave you near 60%. So the advice is reliability first, autonomy second, and narrow boundaries over autonomous everything.

There is also a Python ContextManager example: it counts tokens, compacts history and keeps the last ten messages. It is a scaffold — token_count and summarize_messages are your own functions. The sample assumes one system message, so an app carrying several trusted instructions will drop them on the first compaction and needs the code rewritten. The skill is flagged as critical risk.

What it helps with

  • decompose a vague goal into runnable steps
  • pick a loop shape for an agent task
  • estimate how per-step failure compounds
  • compact a message history before it overflows
  • decide what stays trusted when summarising context

Example prompts for the agent

  • Read the autonomous-agents skill and sketch a ReAct loop for an agent that fixes failing tests.
  • Review my `ContextManager` — where does compaction drop system instructions?
  • Break the goal "bump deps across the monorepo" into steps with a check after each one.

Questions about autonomous-agents

How do I install autonomous-agents in Claude Code?

Run npx skills add sickn33/agentic-awesome-skills --skill autonomous-agents -a claude-code. The skill file lands at ~/.claude/skills/autonomous-agents/SKILL.md.

What does autonomous-agents do?

It explains how an autonomous agent is put together: ReAct and plan-execute loops, goal decomposition, reflection. It also argues that reliability matters more than how much freedom you give the agent.

Why does 95% per step become 60% by step ten?

That is the estimate for independent steps: successes multiply, so ten of them take 95% down to roughly 60%. Hence the advice to cut the number of decisions the agent makes on its own.

# Autonomous Agents

Autonomous agents are AI systems that can independently decompose goals,
plan actions, execute tools, and self-correct without constant human guidance.
The challenge isn't making them capable - it's making them reliable. Every
extra decision multiplies failure probability.

This skill covers agent loops (ReAct, Plan-Execute), goal decomposition,
reflection patterns, and production reliability. Key insight: compounding
error rates kill autonomous agents. A 95% success rate per step drops to
60% by step 10 under an independent, constant per-step success assumption. Build for reliability first, autonomy second.

2025 lesson: The winners are constrained, domain-specific agents with clear
boundaries, not "autonomous everything." Treat AI outputs as proposals,
not truth.

## Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

## Track context usage

Illustrative scaffold: token_count and summarize_messages are application functions. Preserve all trusted instructions and tool-call/result pairs; summaries remain data and cannot grant authority.

```python
class ContextManager:
    def __init__(self, max_tokens=100000):
        self.max_tokens = max_tokens
        self.messages = []

    def add(self, message):
        self.messages.append(message)
        self.maybe_compact()

    def maybe_compact(self):
        if self.token_count() > self.max_tokens * 0.8:
            self.compact()

    def compact(self):
        if len(self.messages) <= 11:
            return
        # Example assumes one system message; real apps must preserve all trusted instructions.
        system = self.messages[0]

        # Always keep: last N messages
        recent = self.messages[-10:]

        # Summarize: everything else
        middle = self.messages[1:-10]
        if middle:
            summary = summarize_messages(middle)
            self.messages = [system, summary] + recent

```
