Evaluating Agent-Skill & MCP Repos

Triage GitHub repos for useful agent skills or MCP servers. Use when a user posts one or more GitHub repo links with a request like "check these repos for useful skills" / "can we use any of the MCP servers in this repo?" and you need to decide what (if anything) to adopt. The skill's job is triage before import — do a fast, structured scan so you only import what is genuinely useful, non-overlapping, and usable without credentials you don't have. Then follow importing-agent-skills (for SKILL.md packs) or mcp-server-management (for wiring MCP servers) for the actual install.

Step 0 — Classify the repo before doing anything​

Not every GitHub repo is a skill pack. Cloning and scanning (cheap, --depth 1) decisively separates three archetypes that must NOT be treated the same:

  1. Real skill pack — contains a top-level skills/ dir or a set of */SKILL.md folders. Directly importable. (e.g. anthropics/skills, ComposioHQ/awesome-claude-skills top level.)
  2. Link directory / "awesome" list — a giant curated README (often 100KB+), zero local SKILL.md files. Nothing to bulk-import; it's an index of other repos. (e.g. VoltAgent/awesome-agent-skills = 241KB README, 0 SKILL.mds.) Say so plainly and offer to follow specific links instead.
  3. MCP-server repo — the code is runnable servers (e.g. modelcontextprotocol/servers → src/<server>/). These are adopted by wiring them into the runtime, NOT by copying SKILL.md files. Grep the README for the server list; most are npx -y @modelcontextprotocol/server-<name>.

Fast check on clone:

git clone --depth 1 "$URL" /tmp/check-<name>
ls /tmp/check-<name>
find /tmp/check-<name>/skills -maxdepth 2 -name SKILL.md 2>/dev/null | wc -l   # real pack? count
wc -c README.md                                                               # huge README => directory
ls src/                                                                        # mcp-server repo?

Step 1 — Enumerate skill names (for real packs)​

SKILL.md files carry a name: in frontmatter that may differ from the folder name — read the actual frontmatter, don't trust the dir name:

for d in */; do d="${d%/}"; [ -f "$d/SKILL.md" ] && \
  echo "$(grep -m1 '^name:' "$d/SKILL.md" | sed 's/name: *//')  [$d/]"; done

Watch for nested packs too — a subdirectory like composio-skills/ can hold hundreds of nested SKILL.mds. find <dir> -name SKILL.md | wc -l reveals them.

Step 2 — Overlap check​

Compare the discovered names against what's already installed (run hermes skills list | grep -i <category>; note ASCII-table truncation of long names — count by category or grep a unique prefix). Flag duplicates explicitly so you don't re-import e.g. brand-guidelines, canvas-design, internal-comms, mcp-builder, skill-creator, theme-factory, webapp-testing, web-artifacts-builder, docx/pdf/pptx/xlsx which ship bundled in Hermes or were imported from anthropics/skills earlier.

Step 3 — Credential / runtime dependency gate​

Read each candidate SKILL.md's frontmatter + body head. The two things that make a skill useless standalone:

  • A requires: frontmatter field listing an MCP server (requires: mcp: [rube]) — nearly all *_automation wrapper skills (e.g. composio-skills/'s 800+ toolkits) are thin wrappers over a specific MCP platform and are NOT useful without it.
  • Instructions that demand an external account/API key/CLI in the Quick Start (register at platform.composio.dev, pip install langsmith-fetch, Plugin install steps). These are platform-onboarding skills.

Self-contained wins: skills heading "When to Use / What This Skill Does / Steps 1..N" with no install step are pure workflow instructions that work with zero setup (e.g. changelog-generator, content-research-writer, file-organizer, image-enhancer, tailored-resume-generator, lead-research-assistant, meeting-insights-analyzer, video-downloader).

Step 4 — MCP-server selection​

For an MCP-server repo, compare candidates against capabilities Hermes already has natively or via enabled servers (check hermes mcp list first — only github was enabled here). Rule of thumb for modelcontextprotocol/servers-style reference servers:

  • Worth wiring: memory (knowledge-graph persistence), sequentialthinking (structured problem-solving), git (git ops — valuable for heavy git users).
  • Redundant: filesystem, fetch, time (Hermes has native file/web/time tooling), everything (test server).
  • Prefer servers that give a capability gap (new tool surface) over cosmetic/config ones.

Step 5 — Present a recommendation, then ask​

Always end with a concrete recommended subset and a clarify() offering it vs. alternatives. Do not bulk-import everything sight-unseen. Be explicit about why excluded items were skipped (overlap / creds / platform-bound) so the user can veto.

Pitfalls​

  • Don't treat a link-directory as an import source. If the clone has 0 SKILL.md files and a huge README, DON'T run the import copy loop against it — there's nothing to copy; report it as an index and pick specific links.
  • Don't trust ls on the source repo: anthropics/skills/ clone listed subdirs; the actual skill contents were under skills/. Always ls skills/ inside a freshly cloned pack, not the repo root.
  • Check overlap against installed skills first — otherwise you import near-duplicates (e.g. artifacts-builder ≈ web-artifacts-builder) and create confusing parallel skills.
  • A skill is not free just because it's in a "skills" repo — many packs mix standalone workflow skills with platform-bound ones in the same listing; the credential gate (step 3) is the step people skip.
  • Imports register at next session start, not the current one — say so when you finish installing so the user knows newly-added skills won't be live in the running session.
  • The category you import into is a free choice (any subdirectory under ~/.hermes/skills/); a single named source category (e.g. anthropic) keeps provenance visible and makes later cleanup easier.
