What it does
Gentle AI Skill Registry is an agent skill from Gentleman-Programming/gentle-shell. Trigger: update skills, skill registry, actualizar skills, after skill changes. Index available skills by trigger and path.
Its SKILL.md is about 580 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 repository describes itself as: Gentle Shell is a Pi-native coding-agent harness for controlled development with Organic Driven Development, optional SDD/OpenSpec, subagents, TDD evidence, review guardrails… The licence is MIT.
When your agent uses it
- Tasks that involve Skill management
Example prompts
- “/gentle-ai-skill-registry”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Scan all known user and project skill directories for */SKILL.md.
- Read frontmatter only as needed to extract name and description trigger text.
- Render .atl/skill-registry.md with scanned sources, registry contract, skill name, trigger/description, scope, and exact path.
- Persist to Engram when available using title: skill-registry, topic_key: skill-registry, type: config, and capture_prompt: false.
- Return the registry path, skill count, cache status, and whether Engram was updated.
What it can do on your machine
Read from SKILL.md and the folder at commit e06582a. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Gentle AI Skill Registry loads about 580 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 270 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.

Activation Contract
Use this skill after installing, removing, creating, moving, or renaming skills, or when a delegator needs a fresh skill index.
Hard Rules
- The registry is an index, not a compiler or summary.
SKILL.mdremains the source of truth. - Do not generate or inject compact rules by default; preserve author intent by passing exact skill paths to subagents.
- Always write
.atl/skill-registry.mdregardless of SDD persistence mode. - Save the registry to Engram as
topic_key: skill-registrywhen available, withcapture_prompt: false. - Skip
sdd-*,_shared, andskill-registry; deduplicate by skill name, preferring project-level skills over user-level skills. - Add
.atl/to.gitignorewhen possible unless explicitly disabled.
Decision Gates
| Situation | Action |
|---|---|
| Same skill exists globally and in project | Keep the project-level skill |
| Same skill exists in multiple global locations | Keep the first source in scan order |
| No skills found | Write an empty registry so agents stop searching blindly |
| Agent will delegate work | Select matching registry rows and pass their SKILL.md paths |
Execution Steps
- Scan all known user and project skill directories for
*/SKILL.md. - Read frontmatter only as needed to extract
nameanddescriptiontrigger text. - Render
.atl/skill-registry.mdwith scanned sources, registry contract, skill name, trigger/description, scope, and exact path. - Persist to Engram when available using
title: skill-registry,topic_key: skill-registry,type: config, andcapture_prompt: false. - Return the registry path, skill count, cache status, and whether Engram was updated.
Output Contract
Return:
- Project name and
.atl/skill-registry.mdpath. - Number of indexed skills.
- Whether the cache was hit or regenerated.
- Any skipped or duplicate skills when relevant.
