Agent skill
observe
Watch and report current state of a target system, process, or entity. Use when monitoring status, inspecting live systems, checking current conditions, or observing runtime behavior.

Intent
Observe and report the current state of a specified target without modifying it. This is the foundation for situational awareness and state modeling.
Success criteria:
- Current state accurately captured with timestamp
- Relevant aspects of the target documented
- At least one evidence anchor per observation
- Uncertainty explicitly noted where state is ambiguous
Compatible schemas:

Inputs
| Parameter | Required | Type | Description |
|---|---|---|---|
target |
Yes | string | What to observe (file path, URL, process, system) |
aspects |
No | array[string] | Specific aspects to focus on (e.g., ["status", "errors", "metrics"]) |
depth |
No | string | Observation depth: surface, detailed, exhaustive |
Procedure
-
Identify observation target: Clarify exactly what system, process, or entity to observe
- Validate target is accessible and observable
- Determine appropriate observation method (read file, query API, check process)
-
Select observation aspects: Determine what properties/attributes to capture
- If aspects not specified, observe: status, configuration, recent changes, anomalies
- Prioritize aspects relevant to apparent context or goal
-
Capture current state: Execute observation without modifying target
- Use Read for file-based targets
- Use Bash for process/system state (ps, systemctl status, etc.)
- Record timestamp of observation
-
Document observations: Structure findings with evidence
- Note what was observed and when
- Highlight notable conditions or anomalies
- Record uncertainty where state is unclear
-
Ground claims: Attach evidence anchors to all observations
- Format:
file:linefor file content - Format:

Output Contract
Return a structured object:
observation:
target: string # What was observed
timestamp: string # ISO 8601 timestamp
status: string # Overall status assessment
aspects:
- aspect: string # Name of observed aspect
value: any # Observed value or state
notable: boolean # Whether this is noteworthy
anomalies: array[string] # Unexpected findings
confidence: 0..1 # Based on observation quality
evidence_anchors: ["file:line", "command:output"]
assumptions: [] # What was assumed about the target
next_actions: array[string] # 0-3 suggested follow-ups
Field Definitions
| Field | Type | Description |

string | When observation was made |
observation.status |
string | Summary status (healthy, degraded, error, unknown) |
observation.aspects |
array | List of observed aspects with values |

number | 0.0-1.0 based on observation completeness |
evidence_anchors |
array[string] | References to raw observation data |
Examples
Example 1: Observe Process Status
Input:
target: "web-server process"
aspects: ["running", "memory", "connections"]
Output:
observation:
target: "nginx process (PID 1234)"
timestamp: "2024-01-15T10:30:00Z"
status: "healthy"
aspects:
- aspect: "running"
value: true
notable: false
- aspect: "memory"
value: "125MB RSS"
notable: false
- aspect: "connections"
value: 847
notable: true
anomalies:
- "Connection count higher than typical (avg: 200)"
confidence: 0.95
evidence_anchors:
- "command:ps aux | grep nginx"
- "command:netstat -an | grep :80"
assumptions:
- "Process identified by name 'nginx'"
next_actions:
- "Monitor connection trend over time"
- "Check for connection leak if count continues rising"
Example 2: Observe File State
Input:
target: "config/database.yml"
aspects: ["content", "permissions", "modified"]
Output:
observation:
target: "config/database.yml"
timestamp: "2024-01-15T10:35:00Z"
status: "present"
aspects:
- aspect: "content"
value: "PostgreSQL configuration with production credentials"
notable: true
- aspect: "permissions"
value: "644"
notable: true
- aspect: "modified"
value: "2024-01-14T15:22:00Z"
notable: false
anomalies:
- "File permissions allow group/other read (sensitive credentials)"
confidence: 0.9
evidence_anchors:
- "config/database.yml:1-25"
- "command:ls -la config/database.yml"
assumptions:
- "File contains database credentials based on content inspection"
next_actions:
- "Review file permissions for security"
- "Consider using environment variables for credentials"
Verification
- Observation timestamp is current (within observation window)
- At least one aspect was observed and documented
- Evidence anchors exist for each notable observation
- Target was not modified during observation
- Anomalies are supported by evidence
Verification tools: Read (to verify file observations)
Safety Constraints
mutation: falserequires_checkpoint: falserequires_approval: falserisk: low
Capability-specific rules:
- NEVER modify the target during observation
- Do not access targets outside authorized scope
- Report access failures rather than attempting workarounds
- Note uncertainty when observations may be stale or incomplete
Composition Patterns
Commonly follows:
search- Observe specific targets found through searchretrieve- Observe content retrieved by reference
Commonly precedes:
state- Observations feed into world state modelingdetect- Observations provide data for pattern detectioncompare- Observations enable comparison with expected state
Anti-patterns:
- Never use observe for modification (use
mutate) - Avoid observe for pattern matching (use
detect)
Workflow references:
- See
reference/workflow_catalog.yaml#debug_code_changefor observation in debugging - See
reference/workflow_catalog.yaml#world_model_buildfor observation in modeling
