trace

trace is a skill for Claude Code from mirkobozzetto/arsenal. It costs 15 tokens per session (226 once invoked), scanned A, original, MIT.

A project progress ledger stored in `.claude/trace.md`. It records file changes automatically and lets you add or review the reasons and work behind them.

In plain words
What is it for?
Use it to read recent project activity, record completed or ongoing work, and attach notes such as changed files, task identifiers, status, or brief context.
Why use it?
It keeps a durable record of what changed during coding sessions, including context that automatic file tracking cannot determine. This helps you remember and review progress without maintaining a separate log.

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

trace 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/trace.cjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Trace

Use scripts/trace.cjs for reading or requested entries in .claude/trace.md. No new format or LLM reviewer. The mechanical hook records file activity, not successful delivery; never upgrade wip to shipped without evidence.

Keep this cross-session activity log distinct from a ship run's task intent. Do not copy every event between them. The runtime owns process/evidence state. Only record a manual intent entry when asked. Read recent entries and stop; do not reopen the work they describe.

Execution policy

Work solo. Ask before any subagent or reviewer, even in auto mode. Explain the independent scope and expected benefit first. No hidden advisor, nested delegation, model retuning, repeated successful checks, or progress spam. Use existing context before asking questions. Stop when the requested result is delivered. User stops and scope changes override pending steps.

Files

What ships with it

2 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.
