SKILLmama eliminates the hours spent researching which library, SDK, or tool to use — it scans your project's actual stack, searches across 4 tiers of the ecosystem plus a companion-skills pass, and returns the top 3 ranked picks with scored evidence. No more Reddit threads or outdated blog posts; just the right tool for your exact setup, with install commands and links, in seconds. Works with Claude Code, Claude.ai, OpenAI Codex, and Antigravity.

📖 Build-in-public series on Dev.to:
Part 1 — scoring formula, 5-tier search, end-to-end example. Part 2 — security gate, SQP rules, companion skills. Part 3 — project scanner, Flow B, gap analysis. Part 4 — Phase 1.5, constraint confirmation in Flow A. Part 5 — tested my own install instructions, found they were wrong. Part 6 — eval harness, trigger-classification tests, bugs found by testing instead of assuming. Part 7 — paired skill-on/skill-off ablation, the deployment persistence check it exposed, and the live CVE it later caught. Part 8 — building the live OSV.dev and npm publisher-continuity checks, and the real CVE that proved them. Part 9 — the mechanical/judgment boundary, the conformance test, and the crates.io extension.
| Agent | How |
|---|---|
| Claude Code | npx skills add Magithar/SKILLmama -a claude-code -g |
| Claude.ai | Zip skillmama/ and upload it under Customize → Skills (steps) |
| OpenAI Codex | Copy one file into ~/.codex/skills/ (steps) |
| Antigravity | Copy one file into ~/.gemini/config/skills/ (steps) |
Codex and Antigravity need the manual copy because of an upstream CLI bug (details).
The upstream CLI works correctly for Claude Code:
npx skills add Magithar/SKILLmama -a claude-code -g
Installs to ~/.claude/skills/skillmama/. Pass -a claude-code explicitly: without it the CLI
auto-detects the calling agent from the environment, so running it from inside another agent's
shell installs to that agent instead.
Then type /skillmama in any Claude Code session.
skillmama/ folder:
zip -r skillmama.zip skillmama/
skillmama.zip/skillmama in any Claude.ai conversationCodex has a native global skills directory, ~/.codex/skills/. The upstream CLI does not
write there (why), so copy it yourself:
mkdir -p ~/.codex/skills/skillmama
curl -sL https://raw.githubusercontent.com/Magithar/SKILLmama/main/skillmama/SKILL.md \
-o ~/.codex/skills/skillmama/SKILL.md
Then ask naturally: codex "find me the best job queue for this project".
Codex was live-tested on 2026-09-27 with an explicit /skillmama invocation.
The run scanned this repository, asked for constraints, searched all four tiers
plus companion skills, produced scored results, and reported unavailable
security evidence as unverified rather than claiming a pass.
Global skills live in ~/.gemini/config/skills/, which is shared by all three Antigravity
surfaces (2.0, IDE, and the agy CLI) since Google consolidated their config. Confirmed by live
testing here and independently in
#1470, including extraction
from the agy binary's own embedded docs.
mkdir -p ~/.gemini/config/skills/skillmama
curl -sL https://raw.githubusercontent.com/Magithar/SKILLmama/main/skillmama/SKILL.md \
-o ~/.gemini/config/skills/skillmama/SKILL.md
Fully restart Antigravity (skills load at startup), then ask "Which skills are installed?"
to confirm. SKILLmama should appear in the list and in the / command picker.
For a project-scoped install instead, put it in <workspace>/.agents/skills/skillmama/SKILL.md.
Usage — invoke explicitly, confirmed working via live testing: type / and select SKILLmama from the picker (or type SKILLmama before your request), then your capability question:
SKILLmama find me the best vector database for a Python project
This triggered the real pipeline in testing — a Phase 1.5 constraint question ("do you have any specific constraints or preferences? ... Reply 'none' to search with no filters"), not a generic answer. Plain natural-language prompts with no explicit SKILLmama invocation were not confirmed to auto-trigger the skill — invoke it explicitly for reliable results.
Per Antigravity's official Agent Skills docs, the agent is also supposed to auto-trigger relevant skills from context alone, without explicit invocation — driven by the skill's
description:frontmatter. We haven't verified that mode here (only explicit invocation was tested), so treat auto-trigger as unconfirmed and invoke explicitly for now.
⚠️
npx skills add Magithar/SKILLmama -a antigravity -greports success but writes to~/.agents/skills/, which Antigravity never reads. Still reproduces onskills@1.7.6(2026-11-06). See why.
skill-land installs to several agents in one command and
exits non-zero if the file didn't land:
npx skill-land Magithar/SKILLmama --for claude-code,codex,antigravity
npx skill-land Magithar/SKILLmama --for codex --verify
Not required. The copy commands above work on their own.
For Codex and Antigravity, npx skills add ... -g prints Done! and exits 0 while writing
to ~/.agents/skills/, a directory neither agent reads. Re-verified on skills@1.7.6, the latest
release, on 2026-11-06.
The root cause is
isUniversalAgent(): agents
whose project dir is .agents/skills get misclassified, and their globalSkillsDir is discarded.
13 agents are affected.
Tracked in #1060 and #1470. Two proposed fixes, PR #1483 and PR #2028, were closed without merging (checked 2026-11-06).
Until a released CLI version fixes this, copy the file yourself using the per-agent instructions above. Each one is two lines and lands in the directory that agent actually reads.
/skillmama ← scans your project and asks what to find
/skillmama find me a vector database for my FastAPI project
/skillmama what auth library should I use for my Next.js app?
/skillmama find a .dwg parser for Node.js
Without an agent, the skillmama CLI runs the deterministic checks:
npx skillmama scan
npx skillmama check lodash --version 4.17.15
One file, skillmama/SKILL.md, runs on every platform. Only the install location differs.
| AI System | Global skill directory | npx skills add -g | skill-land |
|---|---|---|---|
| Claude Code | ~/.claude/skills/skillmama/ | ✅ correct | ✅ |
| OpenAI Codex | ~/.codex/skills/skillmama/ | ❌ writes to ~/.agents/skills/ | ✅ |
| Antigravity | ~/.gemini/config/skills/skillmama/ | ❌ writes to ~/.agents/skills/ | ✅ |
| Claude.ai | n/a, upload only | n/a | n/a |
Project-scoped installs go in .claude/skills/ for Claude Code and .agents/skills/ for Codex
and Antigravity.
Notes:
skills@1.5.22 on 2026-08-08; re-verified on skills@1.7.6 on
2026-11-06 — still unfixed.skills CLI only discovers files named SKILL.md. Repos that ship per-platform variants
under other names are invisible to it.skillmama/ folder and upload via Customize → Skills.Stars on GitHub
Helps you take a change from a rough idea or bug report through to a tested, reviewed result, with each step handled by a focused skill. Its skills cover pinning down domain terms, designing module interfaces, diagnosing hard bugs, and reviewing changes against your repo's coding standards.
@mattpocockA development methodology for coding agents that makes the agent brainstorm before building, follow plans, run parallel work and finish branches in a disciplined way. You get fewer skipped steps and more consistent results from your coding assistant.
@obraGives your coding agent a planning, testing and review routine to follow on every task. It plans before building, checks changes with tests, has a fresh reviewer look for regressions, and saves repeated wins as reusable skills.
@affaan-mDeveloper tools for working on the React codebase itself. Provides skills for extracting error messages, managing and debugging feature flags across release channels, running Flow type checks, and fixing lint and formatting issues before committing.
@facebookFinds and ranks libraries, SDKs, and tools that fit your project's stack, searching package registries and checking candidates with a built-in security gate. Works with Claude Code and other AI coding assistants. Install it with the command on its page. It includes skillmama. Its skills do not fire on their own yet. Free and open source.
