agent-invocation-tracking

agent-invocation-tracking is a skill for Claude Code, Codex from paruff/uFawkesAI. It costs 37 tokens per session (547 once invoked), scanned A, original, MIT.

An observability guide for recording when an AI agent starts and finishes work, how long it takes, and whether it succeeds.

In plain words
What is it for?
Use it when adding OpenTelemetry tracking to agent invocations, including task triggers, input files, duration, loaded skills, and findings.
Why use it?
It creates measurements that show which agents are used often, run slowly, or fail frequently.

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

agent-invocation-tracking 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 4d 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.

Skill: Agent Invocation Tracking

Load trigger: "load agent-invocation-tracking skill" > DORA: Cap 2 (Observability) Token cost: Low

Purpose

Track when agents start, complete, and how long they take. Enables answering: "Which agents are used most? Which take longest? Which fail most often?"

Span Specification

agent.invocation.started

Emit when the agent begins processing.

Attributes:

Attribute Type Description
agent.name string Agent identifier (matches filename without .md)
session_id string Unique invocation identifier
mode string Operational mode (if agent supports multiple)
trigger string What triggered this invocation (human request, CI, direct invocation)
input_files string[] Files read as context for this invocation

agent.invocation.completed

Emit when the agent finishes.

Attributes (all from started, plus):

Attribute Type Description
duration_ms integer Wall-clock duration in milliseconds
total_skills_loaded integer Count of skills loaded during invocation
total_findings integer Count of findings produced
decision string Final decision (PASS/FAIL/BLOCKED/APPROVE/REQUEST_CHANGES/ESCALATE)

agent.invocation.failed

Emit when the agent encounters an error it cannot recover from.

Attributes (all from started, plus):

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.
