What it does

Analyze Io Traces is an agent skill from moeru-ai/airi. Read and analyze AIRI IO traces that Tamagotchi saved to local files. Use when the user asks why a chat, speech, or audio turn was slow, failed, or behaved wrongly, and recording is enabled in Settings System Developer.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 💖🧸 Self hosted, you-owned Grok Companion, a container of souls of waifu, cyber livings to bring them into our worlds, wishing to achieve Neuro-sama's altitude. Capable of… The licence is MIT.

When your agent uses it

  • The user asks why a chat
  • Audio turn was slow
  • Behaved wrongly
  • Recording is enabled in Settings System Developer

Example prompts

  • “/analyze-io-traces”

What it can do on your machine

Read from SKILL.md and the folder at commit ec682e2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq
    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Analyze Io Traces loads about 542 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 177 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~542

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Read and analyze AIRI IO traces that Tamagotchi saved to local files. Use when the user asks why a chat, speech, or audio turn was slow, failed, or behaved wrongly, and recording is enabled in Settings > System > Developer.

Analyze IO traces

Tamagotchi saves each ended IO span as one JSON line when Record IO traces automatically is on. The setting is under Settings > System > Developer.

Find the files

Files are named <start time>.jsonl. A new file starts each time recording starts. Files older than seven days are deleted.

sh
ls -t "$HOME/Library/Application Support/ai.moeru.airi/io-traces"/*.jsonl | head -3
ls -t "$HOME/Library/Application Support/@proj-airi/stage-tamagotchi/io-traces"/*.jsonl | head -3

The first path is the packaged app on macOS. The second is pnpm dev on macOS. If APP_USER_DATA_PATH is set, use $APP_USER_DATA_PATH/io-traces. If recording is off or nothing ran yet, the folder does not exist. Ask the user to turn it on and reproduce the problem.

Record shape

Each line is one span with traceId, spanId, parentSpanId, name, startTimeNano, endTimeNano, status.code (2 means error), attributes, and events. Time values are decimal strings in nanoseconds. A trace is one interaction turn. Subsystems are in attributes["ai.moeru.airi.io.subsystem"].

Common queries

Set F to the newest file first.

sh
# Spans by name, slowest first, in milliseconds
jq -r '[.name, ((.endTimeNano|tonumber)-(.startTimeNano|tonumber))/1e6] | @tsv' "$F" | sort -t$'\t' -k2 -nr | head -20

# Spans with an error status
jq -c 'select(.status.code == 2) | {name, traceId, message: .status.message}' "$F"

# All spans of one trace in start order
jq -c 'select(.traceId == "TRACE_ID")' "$F" | jq -s 'sort_by(.startTimeNano|tonumber)'

# Time to first token for each LLM span
jq -c 'select(.events | any(.name | endswith("llm.first_token"))) | {traceId, events}' "$F"

Limits

Spans are saved only after they end. A call that never ends is not in the file. Spans record timing and counts, not prompts or replies. Say so when the cause needs content.
