observe

observe is a skill for Claude Code from synaptiai/agent-capability-standard. It costs 35 tokens per session (1,550 once invoked), scanned A, original, Apache-2.0.

A read-only monitoring skill for reporting the current state of a file, URL, process, system, or other target, with timestamps and evidence.

In plain words
What is it for?
Use it to inspect status, configuration, recent changes, errors, metrics, or unusual conditions.
Why use it?
It provides a structured view of what is happening without changing the system being checked.

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

observe 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

  • schemas/output_schema.yaml

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

  1. 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)
  2. 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
  3. 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
  4. Document observations: Structure findings with evidence

    • Note what was observed and when
    • Highlight notable conditions or anomalies
    • Record uncertainty where state is unclear
  5. Ground claims: Attach evidence anchors to all observations

    • Format: file:line for file content
    • Format: command:output for system observations

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

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

observe is a skill published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 7d ago), licensed Apache-2.0. It adds 35 tokens to every session and 1,550 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
