What this skill does

Reads your existing skills from phucbm/skills README, scans the current codebase, diffs the two, and presents a ranked list of save/update candidates with recommended file paths. You pick which ones to act on.

Steps

Phase 1 — Pull existing skills index (read README only)

gh repo clone phucbm/skills /tmp/phucbm-skills 2>/dev/null || git -C /tmp/phucbm-skills pull

Read /tmp/phucbm-skills/README.md only. Extract:

• Knowledge table: topic names and descriptions (what's already saved)
• Skills table: skill names (operational skills already known)

Phase 2 — Scan current codebase (run in parallel)

Read these in parallel:

• package.json / composer.json / pyproject.toml / Cargo.toml / go.mod — deps and scripts
• Config files at root: next.config.*, vite.config.*, drizzle.config.*, biome.jsonc, playwright.config.*, tailwind.config.*
• .github/workflows/*.yml — CI/CD patterns
• scripts/ directory — custom tooling
• Key source entry files: lib/, src/, app/ top-level only (don't recurse deep — read index/entry files)
• .claude/CLAUDE.md and .claude/docs/ if present — already-documented patterns

Extract topics: libraries used, non-obvious configurations, custom patterns, architectural decisions, CI/CD tricks.

Phase 3 — Diff and rank

Cross-reference found topics against existing README knowledge and skills tables.

Produce two lists with recommended file paths for every item:

NEW — topics found in codebase with no match in existing knowledge/skills:

[N] Topic name — one-line reason it's worth saving
    skill:     skills/<topic>/SKILL.md
    knowledge: knowledge/<category>/<slug>.md

If multiple new topics share knowledge (e.g. rag + pinecone), show the relationship:

[N] RAG pipeline — generic chunk→embed→query pattern, reusable with any vector DB
    skill:     skills/rag/SKILL.md
    knowledge: knowledge/rag/concepts.md

[N+1] Pinecone — vector DB setup, upsert, query, metadata filters
    skill:     skills/pinecone/SKILL.md
    knowledge: knowledge/pinecone/setup.md
    note:      skills/rag will also reference knowledge/pinecone/setup.md

UPDATE — topics that overlap an existing entry but the codebase shows something new:

[N] update: <existing-topic> — what's new or different
    file: knowledge/<category>/<slug>.md

Rank by: reusability across projects × non-obviousness (things you'd have to figure out again from scratch).

Skip topics that are: trivial to look up, fully covered already, or project-specific with no transfer value.

Phase 4 — User picks, then act

Present the full list and ask: "Which ones to save? (e.g. 1, 3, update 4 — or 'all')"

Wait for response. Then for each selected item:

• NEW picks → invoke add-skill flow: draft skills/<topic>/SKILL.md + knowledge/<category>/<slug>.md, show both, confirm, push
• UPDATE picks → invoke update-skill flow: show diff of proposed changes to existing knowledge file, confirm, push

Each item is confirmed individually. Never batch-push without showing what will change.

After all pushes: confirm final state and remind user to run /plugin marketplace update phucbm in other projects to get the new skills.

Rules

• Phase 1 reads README.md only — no file tree scanning of the skills repo (saves tokens)
• Phase 2 reads breadth-first — top-level files only, don't recurse into deep source dirs
• Always output recommended file paths in Phase 3 — user must confirm names before any files are written
• Skills are flat: skills/<topic>/SKILL.md — one level only, no bucket subdirectories
• Knowledge can be namespaced: knowledge/<category>/<slug>.md — flag when shared across skills
• Never suggest saving secrets, API keys, or project-specific data (user IDs, URLs, credentials)
• Knowledge files are generic — cite specific projects as examples only, never as facts
• Always confirm per-item before pushing
• If nothing new is found, say so clearly rather than inventing suggestions
