What it does
Scan Logs is an agent skill from marin-community/marin. Use scripts/logscan.py only when explicitly requested to scan an oversized log or to perform Gemini-backed log analysis.
Its SKILL.md is about 440 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: Open-source framework for the research and development of foundation models. The licence is Apache-2.0.
Example prompts
- “/scan-logs”
Requirements
- A credential in GEMINI_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 61bb85c. 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:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, 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:
GEMINI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Scan Logs loads about 438 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 173 words of instructions outside code blocks.
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.

Scan large logs
grep finds matching original lines; summarize produces a Markdown report.
They can run independently or as a pipeline.
Prerequisites
GEMINI_API_KEY must be set. The log is sent to an external Gemini API and
incurs model usage; do not send secrets or sensitive logs without approval.
Modes
grep — find matching lines
Returns line-numbered original lines matching a natural-language query.
uv run scripts/logscan.py grep <logfile> "<query>"summarize — produce a markdown report
Summarizes the log around the query, hierarchically reducing large inputs.
uv run scripts/logscan.py summarize <logfile> "<query>"Output is a markdown report on stdout.
Piping modes together
Narrow first, then summarize through --stdin:
uv run scripts/logscan.py grep log.txt "errors" \
| uv run scripts/logscan.py summarize --stdin "summarize these errors"Behavior-changing options are --chunk-tokens, --concurrency, --model,
--stdin, and --verbose. The defaults are 5,000-token grep chunks,
50,000-token hierarchical summarize chunks, concurrency 16, and
gemini-2.5-flash-lite. Smaller grep chunks favor precise line matching;
large logs need no manual pre-split. Inspect --help before overriding them.
Output
- grep: Line-numbered matching lines to stdout. Progress to stderr.
- summarize: Markdown report to stdout. Progress and token usage to stderr.
Both modes report progress and token usage to stderr. Read the matched source lines before accepting a generated diagnosis.
