What it does
Stale Content Review is an agent skill from ArmDeveloperEcosystem/arm-learning-paths. Scan Arm Learning Paths and install guides for stale-content risk. Use when the user asks to periodically flag content that may need maintenance, freshness review, dependency drift review, screenshot or UI review, latest or unpinned version review, or a report of likely stale pages.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/staleness-signals.md` and `scripts/stale_content_scan.py`).
It sits in Education, covering Curriculum and course design. The repository describes itself as: Arm Learning Paths: a repository of how-to content for software developers.
When your agent uses it
- The user asks to periodically flag content that may need maintenance
- Freshness review
- Dependency drift review
- Unpinned version review
Example prompts
- “/stale-content-review”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Identify the review scope. For periodic scans, default to content/learning-paths and content/install-guides.
- Run scripts/stale_content_scan.py for a deterministic first pass.
- Review the highest-scoring files and sample lines before drawing conclusions.
- Summarize what each selected guide or page does, the dependencies or moving parts it relies on, and the review flags a human should…
What it can do on your machine
Read from SKILL.md and the folder at commit 44a1644. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Stale Content Review loads about 991 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 424 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); the scripts in this folder 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 424 words (~991 tokens).
“Use this skill to find Learning Paths and install guides that might need human maintenance review. This skill is report-only by default: flag risk, provide evidence, and leave fixes to the relevant owner unless the user explicitly asks for edits.”
