At a glance

Share agent traces to open datasets on HuggingFace Hub. An agent skill from JayFarei/opentraces.

  • The user mentions OpenTraces
  • SKILL.md covers Current Command Model, Setup, Trace Retrieval and Trace Trails, plus 9 more sections
  • Calls jq and git; needs OPENAI_API_KEY
  • Workflow-built datasets

What it does

Opentraces is an agent skill from JayFarei/opentraces. Share agent traces to open datasets on HuggingFace Hub. Use this skill when the user mentions OpenTraces, trace capture, Trace Trails, workflow-built datasets, dataset review, or publishing reviewed dataset rows.

Its SKILL.md is about 10k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud. It works with Hugging Face. The repository describes itself as: A local-first evidence layer for agent work, capturing what the agent sees, does, and changes.

When your agent uses it

  • The user mentions OpenTraces
  • Workflow-built datasets
  • Publishing reviewed dataset rows

Example prompts

  • “/opentraces”

What it can do on your machine

Read from SKILL.md and the folder at commit 354755d. 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
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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 these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY

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

Context cost

Opentraces loads about 10k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 3,649 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~10k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,649 words (~10,186 tokens).

“OpenTraces captures local agent traces, links them to Git evidence with Trace Trails, lets workflows turn one or more traces into local datasets, and then publishes reviewed dataset rows to HuggingFace remotes.”
