# Autonomous Agents

## Overview

This public intake copy packages `plugins/antigravity-awesome-skills/skills/autonomous-agents` from `https://github.com/sickn33/antigravity-awesome-skills` into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review.

# 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. 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.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Capabilities, Scope, Tooling, Patterns, Basic ReAct Implementation, LangGraph ReAct (Production).

## When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

## Operating Table

| Situation | Start here | Why it matters |
| --- | --- | --- |
| First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow |
| Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source |
| Workflow execution | `SKILL.md` | Starts with the smallest copied file that materially changes execution |
| Supporting context | `SKILL.md` | Adds the next most relevant copied source file without loading the entire package |
| Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts |

## Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. # Combine steps where possible # Prefer fewer, more capable steps over many small ones # Use structured outputs (JSON schemas) # Add validation at each step # Use better models for critical steps
2. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
3. Read the overview and provenance files before loading any copied upstream support files.
4. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
5. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
6. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
7. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.

### Imported Workflow Notes

#### Imported: Reduce step count

# Combine steps where possible
# Prefer fewer, more capable steps over many small ones

#### Imported: Increase per-step reliability

# Use structured outputs (JSON schemas)
# Add validation at each step
# Use better models for critical steps

#### Imported: Capabilities

- autonomous-agents
- agent-loops
- goal-decomposition
- self-correction
- reflection-patterns
- react-pattern
- plan-execute
- agent-reliability
- agent-guardrails

## Examples

### Example 1: Ask for the upstream workflow directly

```text
Use @autonomous-agents-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
```

**Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

### Example 2: Ask for a provenance-grounded review

```text
Review @autonomous-agents-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
```

**Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

### Example 3: Narrow the copied support files before execution

```text
Use @autonomous-agents-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
```

**Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

### Example 4: Build a reviewer packet

```text
Review @autonomous-agents-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.
```

**Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet.

### Imported Usage Notes

#### Imported: Track context usage

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):
        # Always keep: system prompt
        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

## Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

- Reliability over autonomy - every step compounds error probability
- Constrain scope - domain-specific beats general-purpose
- Treat outputs as proposals, not truth
- Build guardrails before expanding capabilities
- Human-in-the-loop for critical decisions is non-negotiable
- Log everything - every action must be auditable
- Fail safely with rollback, not silently with corruption

## Troubleshooting

### Problem: The operator skipped the imported context and answered too generically

**Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-awesome-skills/skills/autonomous-agents`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### Problem: The task drifted into a different specialization

**Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
**Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

                if attempt == max_retries - 1:
                    raise
                self.log_retry(step, attempt, e)

#### Imported: Design for partial failure

### Agent Takes Dangerous Actions

Severity: HIGH

Situation: Agent with broad permissions

Symptoms:
Agent deletes production data. Sends emails to wrong recipients.
Makes purchases without approval. Modifies settings it shouldn't.
Actions that can't be undone.

Why this breaks:
Agents optimize for their goal. Without guardrails, they'll take the
shortest path - even if that path is destructive. An agent told to
"clean up the database" might interpret that as "delete everything."

Broad permissions + autonomy + goal optimization = danger.

### Error Probability Compounds Exponentially

Severity: CRITICAL

Situation: Building multi-step autonomous agents

Symptoms:
Agent works in demos but fails in production. Simple tasks succeed,
complex tasks fail mysteriously. Success rate drops dramatically
as task complexity increases. Users lose trust.

Why this breaks:
Each step has independent failure probability. A 95% success rate
per step sounds great until you realize:
- 5 steps: 77% success (0.95^5)
- 10 steps: 60% success (0.95^10)
- 20 steps: 36% success (0.95^20)

This is the fundamental limit of autonomous agents. Every additional
step multiplies failure probability.

Recommended fix:

#### Imported: Break into checkpointed segments

# Human review at each segment
# Resume from last good checkpoint

### API Costs Explode with Context Growth

Severity: CRITICAL

Situation: Running agents with growing conversation context

Symptoms:
$47 to close a single support ticket. Thousands in surprise API bills.
Agents getting slower as they run longer. Token counts exceeding
model limits.

Why this breaks:
Transformer costs scale quadratically with context length. Double
the context, quadruple the compute. A long-running agent that
re-sends its full conversation each turn can burn money exponentially.

Most agents append to context without trimming. Context grows:
- Turn 1: 500 tokens → $0.01
- Turn 10: 5000 tokens → $0.10
- Turn 50: 25000 tokens → $0.50
- Turn 100: 50000 tokens → $1.00+ per message

### Demo Works But Production Fails

Severity: CRITICAL

Situation: Moving from prototype to production

Symptoms:
Impressive demo to stakeholders. Months of failure in production.
Works for the founder's use case, fails for real users. Edge cases
overwhelm the system.

Why this breaks:
Demos show the happy path with curated inputs. Production means:
- Unexpected inputs (typos, ambiguity, adversarial)
- Scale (1000 users, not 3)
- Reliability (99.9% uptime, not "usually works")
- Edge cases (the 1% that breaks everything)

The methodology is questionable, but the core problem is real.
The gap between a working demo and a reliable production system
is where projects die.

Recommended fix:

#### Imported: Test at scale before production

# Run 1000+ test cases, not 10
# Measure P95/P99 success rate, not average
# Include adversarial inputs

#### Imported: Build observability first

import structlog
logger = structlog.get_logger()

class ObservableAgent:
    def execute(self, task):
        with logger.bind(task_id=task.id):
            logger.info("task_started")
            try:
                result = self._execute(task)
                logger.info("task_completed", result=result)
                return result
            except Exception as e:
                logger.error("task_failed", error=str(e))
                raise

#### Imported: Have escape hatches

# Human takeover when confidence < threshold
# Graceful degradation to simpler behavior
# "I don't know" is a valid response

#### Imported: Deploy incrementally

# Monitor error rates at each stage

### Agent Fabricates Data When Stuck

Severity: HIGH

Situation: Agent can't complete task with available information

Symptoms:
Agent invents plausible-looking data. Fake restaurant names on expense
reports. Made-up statistics in reports. Confident answers that are
completely wrong.

Why this breaks:
LLMs are trained to be helpful and produce plausible outputs. When
stuck, they don't say "I can't do this" - they fabricate. Autonomous
agents compound this by acting on fabricated data without human review.

The agent that fabricated expense entries was trying to meet its goal
(complete the expense report). It "solved" the problem by inventing data.

Recommended fix:

#### Imported: Validate against ground truth

def validate_expense(expense):
    # Cross-check with external sources
    if expense.restaurant:
        if not verify_restaurant_exists(expense.restaurant):
            raise ValidationError("Restaurant not found")

    # Check for suspicious patterns
    if expense.amount == round(expense.amount, -1):
        flag_for_review("Suspiciously round amount")

#### Imported: Require evidence

system_prompt = '''
For every factual claim, cite the specific tool output that
supports it. If you cannot find supporting evidence, say
"I could not verify this" rather than guessing.
'''

#### Imported: Use structured outputs

from pydantic import BaseModel

class VerifiedClaim(BaseModel):
    claim: str
    source: str  # Must reference tool output
    confidence: float

#### Imported: Detect uncertainty

# Train to output confidence scores
# Flag low-confidence outputs for human review
# Never auto-execute on uncertain data

### Integration Is Where Agents Die

Severity: HIGH

Situation: Connecting agent to external systems

Symptoms:
Works with mock APIs, fails with real ones. Rate limits cause crashes.
Auth tokens expire mid-task. Data format mismatches. Partial failures
leave systems in inconsistent state.

Why this breaks:
The companies promising "autonomous agents that integrate with your
entire tech stack" haven't built production systems at scale.
Real integrations have:
- Rate limits (429 errors mid-task)
- Auth complexity (OAuth refresh, token expiry)
- Data format variations (API v1 vs v2)
- Partial failures (webhook received, processing failed)
- Eventual consistency (data not immediately available)

Recommended fix:

#### Imported: Build robust API clients

from tenacity import retry, stop_after_attempt, wait_exponential

class RobustAPIClient:
    @retry(
        stop=stop_after_attempt(3),
        wait=wait_exponential(multiplier=1, min=4, max=60)
    )
    async def call(self, endpoint, data):
        response = await self.client.post(endpoint, json=data)
        if response.status_code == 429:
            retry_after = response.headers.get("Retry-After", 60)
            await asyncio.sleep(int(retry_after))
            raise RateLimitError()
        return response

#### Imported: Handle auth lifecycle

class TokenManager:
    def __init__(self):
        self.token = None
        self.expires_at = None

    async def get_token(self):
        if self.is_expired():
            self.token = await self.refresh_token()
        return self.token

    def is_expired(self):
        buffer = timedelta(minutes=5)  # Refresh early
        return datetime.now() > (self.expires_at - buffer)

#### Imported: Use idempotency keys

# Every external action should be idempotent
# If agent retries, external system handles duplicate

#### Imported: Separate read/write permissions

# Agent can read anything
# Write requires explicit approval

#### Imported: Dangerous actions require confirmation

DANGEROUS_ACTIONS = [
    "delete_*",
    "send_email",
    "transfer_money",
    "modify_production",
    "revoke_access",
]

async def execute_action(action):
    if matches_dangerous_pattern(action):
        approval = await request_human_approval(action)
        if not approval:
            return ActionRejected(action)
    return await actually_execute(action)

#### Imported: Dry-run mode for testing

# Agent describes what it would do
# Human approves the plan
# Then agent executes

#### Imported: Audit logging for everything

# Every action logged with context
# Who authorized it
# What changed
# How to reverse it

### Agent Runs Out of Context Window

Severity: MEDIUM

Situation: Long-running agent tasks

Symptoms:
Agent forgets earlier instructions. Contradicts itself. Loses track
of the goal. Starts repeating itself. Model errors about token limits.

Why this breaks:
Every message, observation, and thought consumes context. Long tasks
exhaust the window. When context is truncated:
- System prompt gets dropped
- Early important context lost
- Agent loses coherence

Recommended fix:

#### Imported: Use external memory

# Don't keep everything in context
# Store in vector DB, retrieve when needed
# See agent-memory-systems skill

#### Imported: Hierarchical summarization

# Recent: full detail
# Medium: key points
# Old: compressed summary

### Can't Debug What You Can't See

Severity: MEDIUM

Situation: Agent fails mysteriously

Symptoms:
"It just didn't work." No idea why agent failed. Can't reproduce
issues. Users report problems you can't explain. Debugging is
guesswork.

Why this breaks:
Agents make dozens of internal decisions. Without visibility into
each step, you're blind to failure modes. Production debugging
without traces is impossible.

Recommended fix:

#### Imported: Structured logging

import structlog

logger = structlog.get_logger()

class TracedAgent:
    def think(self, context):
        with logger.bind(step="think"):
            thought = self.llm.generate(context)
            logger.info("thought_generated",
                thought=thought,
                tokens=count_tokens(thought)
            )
            return thought

    def act(self, action):
        with logger.bind(step="act", action=action.name):
            logger.info("action_started")
            try:
                result = action.execute()
                logger.info("action_completed", result=result)
                return result
            except Exception as e:
                logger.error("action_failed", error=str(e))
                raise
