What it does
Manage Skills is an agent skill from changchangidea-oss/SkillRadar. Audit Codex skill-context pressure, detect duplicate capabilities, and produce a read-only pruning plan for global, project and plugin-provided skills.
Its SKILL.md is about 610 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 Agent Workflows, covering Skill management. The licence is MIT.
When your agent uses it
- Tasks that involve Skill management
Example prompts
- “/manage-skills”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Run the bundled read-only doctor first
- Report these fields before recommending changes
- Use the doctor's recommendations as a plan, not as permission to edit configuration.
- Prefer disabling a redundant skill with [[skills.config]] over uninstalling a whole plugin when other capabilities from that plugin remain…
- Only suggest codex plugin remove ... when the doctor reports a plugin_suggestion, and make clear that plugin removal requires explicit…
- If the user explicitly approves applying the plan, back up ~/.codex/config.toml, reconcile the recommended [[skills.config]] entries, and…
- Re-run the audit after changes and start a fresh Codex thread so the model-visible skills catalog is rebuilt.
What it can do on your machine
Read from SKILL.md and the folder at commit 32f6d91. 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:
nodecodex
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
Manage Skills loads about 614 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 298 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.

Manage Skills
Use SkillRadar's Skill Budget Doctor to keep the model-visible skill catalog compact without blindly deleting useful capabilities.
Required workflow
- Run the bundled read-only doctor first:
node ../../scripts/skill-budget.mjs audit '<current project or task focus>' - Report these fields before recommending changes:
budget.pressure,budget.used,budget.limit, andbudget.ratio;- active/discovered skill counts;
- near-duplicate groups and which skill is the preferred keeper;
- the projected ratio after the proposed pruning plan.
- Use the doctor's
recommendationsas a plan, not as permission to edit configuration. - Prefer disabling a redundant skill with
[[skills.config]]over uninstalling a whole plugin when other capabilities from that plugin remain useful. - Only suggest
codex plugin remove ...when the doctor reports aplugin_suggestion, and make clear that plugin removal requires explicit user approval. - If the user explicitly approves applying the plan, back up
~/.codex/config.toml, reconcile the recommended[[skills.config]]entries, and do not change unrelated settings. - Re-run the audit after changes and start a fresh Codex thread so the model-visible skills catalog is rebuilt.
Codex budget reference
The doctor mirrors current Codex behavior conservatively: the fallback metadata budget is 8,000 characters; when skills.max_context_tokens is configured it uses that token budget up to Codex's 10,000-token cap; individual descriptions are capped at 1,024 characters for the estimate.
Scope guidance
- Keep broadly reusable skills global only when they are actually used across projects.
- Prefer project scope for stack-specific or discipline-specific skills.
- Keep one strong skill instead of several near-duplicates that solve the same task.
- Local/project relevance is a pruning signal, not proof that a skill is useless globally.
- Use
find-skillbefore adding a capability andinspect-skillbefore trusting third-party scripts.
Safety
The doctor is read-only. It does not disable skills, edit config, uninstall plugins, install skills, or execute discovered third-party scripts. Discovery and diagnosis are not execution permissions.
