editing-skills

editing-skills is a skill for Claude Code from ZaxbyHub/opencode-swarm. It costs 95 tokens per session (2,065 once invoked), scanned A, original, MIT.

A set of repository rules for adding, changing, moving, or removing coding-agent skills. It explains how matching skill files in different directories must be kept consistent.

In plain words
What is it for?
Use it when editing SKILL.md files or maintaining skills across the repository’s OpenCode, Claude Code, and agent directories.
Why use it?

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

editing-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Editing Skills in opencode-swarm

Skills in this repo exist across parallel trees (.opencode/skills/, .claude/skills/, .agents/skills/) governed by explicit mirror contracts. Editing a SKILL.md without knowing its contract silently desynchronizes the OpenCode and Claude Code surfaces. Classify first, then edit.

Step 1 — Classify the skill

Look the slug up in src/config/skill-mirrors.ts:

  • MIRRORED_ARCHITECT_MODE_SKILLS (brainstorm, specify, clarify-spec, swarm-resume, clarify, discover, consult, pre-phase-briefing, council, deep-dive, deep-research, issue-ingest, plan, critic-gate, design-docs): .opencode and .claude copies must stay byte-identical. Any edit is a dual-tree edit — apply the identical change to both files.
  • ADAPTER (execute, phase-wrap, swarm-pr-review, swarm-pr-feedback, swarm-pr-subscribe, swarm-ci-monitor): .opencode is canonical; .claude and .agents where present are thin shims that must keep the exact relative reference ../../../.opencode/skills/<slug>/SKILL.md (drift-check verifies the string). swarm-implement follows the same operational adapter pattern, but is currently classified as an additional divergent contract because the additional-contract registry does not yet model non-architect adapter shims.
  • DIVERGENT: both trees exist, content intentionally differs — a single-tree edit is fine. codebase-review-swarm is in DIVERGENT_ARCHITECT_MODE_SKILLS; engineering-conventions is a divergent entry in ADDITIONAL_SKILL_MIRROR_CONTRACTS. swarm-implement and writing-tests are classified divergent only because the additional-contract model does not yet have an adapter kind; operationally, .opencode is canonical and .claude delegates to it.
  • OPENCODE-ONLY: loop (OPENCODE_ONLY_ARCHITECT_MODE_SKILLS) and running-tests (an opencode-only ADDITIONAL contract) — do not create .claude mirrors (a .claude/skills/loop would shadow Claude Code's built-in /loop).
  • ADDITIONAL contracts: commit-pr is divergent (#1692). The .claude copy is the repo-INTERNAL publication protocol (CI's pr-standards workflow declares it the source of truth); the .opencode copy is the PORTABLE, project-agnostic version bundled into end-user projects, so the two trees intentionally differ — do not sync them byte-for-byte. The discovery shims in .agents/skills/commit-pr/ and .github/skills/commit-pr/ point at the repo-internal .claude file as canonical.
  • Adapter skills (issue-tracer): .opencode/skills/<slug>/SKILL.md is the canonical protocol; .claude/skills/<slug>/SKILL.md and .agents/skills/<slug>/SKILL.md are thin shims that reference it via the relative path. See src/config/skill-mirrors.ts for the kind: adapter contract.
  • No skill-mirrors.ts entry (qa-sweep, research-first, swarm, unswarm, tech-debt-ci-review, rust-crate-ci, orchestrating-subagents, durable-session-state, editing-skills, …): the .claude file is the source protocol and there is no .opencode copy, no CI gate, and no npm shipment. But most are not single-file: many have a Codex adapter shim in .agents/skills/<slug>/ that reads ".claude/skills/<slug>/SKILL.md is the source protocol" (check ls .agents/skills/). Content edits to the .claude file are safe — shims delegate — but renaming, moving, or removing one of these skills silently orphans its .agents shim with zero drift-check coverage. Update or remove the shim in the same change.
  • Pre-flight for new skills (blocking): Before authoring any SKILL.md content for a skill that should reach npm users, the slug MUST be registered in all three places: src/config/skill-mirrors.ts (classification), src/config/bundled-skills.ts (BUNDLED_PROJECT_SKILLS), and package.json#files. Creating content first and registering later is a common source of drift-check failures and missing shipments.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

editing-skills is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (467 stars, last pushed today), licensed MIT. It adds 95 tokens to every session and 2,065 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
