## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Paperclip agents can load repository and catalog skills, and Codex renders skill names and frontmatter descriptions into startup context. > - Long descriptions consume the fixed skill metadata budget before Codex can use the progressively disclosed skill bodies. > - The repo `.agents/skills` descriptions and a few shipped catalog descriptions had grown into operational documentation instead of short trigger metadata. > - This pull request keeps the strongest trigger language in frontmatter while leaving detailed procedures in each skill body. > - The benefit is lower prompt overhead, more reliable skill triggering, and a regression guard that prevents description drift from returning. ## Linked Issues or Issue Description No public GitHub issue found for this maintenance item. ### Pre-submission checklist - [x] I have searched existing open and closed issues and this is not a duplicate. - [x] I am working against `master`. - [x] I have confirmed the issue originates in Paperclip's shipped skill metadata, not in a local agent adapter or provider. ### What happened? Codex startup renders discovered skill names and frontmatter descriptions into a fixed skill metadata budget. Several repository skill descriptions and one shipped catalog description had grown into long-form operational guidance, which can force Codex to truncate descriptions before the model has enough trigger signal to select the right skill. ### Expected behavior Skill frontmatter descriptions should stay short trigger summaries: one capability sentence plus a “use when” clause. Detailed procedures should stay in the skill body and load only after the skill triggers. ### Steps to reproduce 1. Inspect `.agents/skills/*/SKILL.md` and `packages/skills-catalog/catalog/**/SKILL.md` frontmatter descriptions. 2. Measure folded YAML `description` values. 3. Observe descriptions above the intended short-trigger range, including descriptions above 300 characters. 4. Run the new shipped catalog test to verify future descriptions stay capped. ### Paperclip version or commit Reproduced on `master` at `cc81eefb6047d8eaf57faf785f421c03dc97073c`. ### Deployment mode Local dev / source checkout metadata inspection. This is not database-related. ### Installation method Built from source. ### Agent adapter(s) involved Codex, because Codex startup uses the skill metadata prompt budget. The metadata source itself is core repository/catalog content. ### Database mode Not database-related. ### Access context Not applicable; this is static repository metadata. ### Node.js version `v22.22.2` in the verification environment. ### Operating system Linux container environment. ### Relevant logs or output Final measurement after this PR: 29 source `SKILL.md` files, max description length 215 chars, 5,449 total description chars, estimated 1,363 description tokens at 4 chars/token. ### Relevant config None. ### Additional context The shipped catalog manifest was regenerated so the generated package metadata matches the edited catalog `SKILL.md` sources. ### Privacy checklist - [x] I have reviewed all pasted output for PII and redacted where necessary. ## What Changed - Shortened long `.agents/skills/*/SKILL.md` frontmatter descriptions to concise capability plus use-when trigger clauses. - Shortened the over-budget shipped skills catalog descriptions for wireframe, Paperclip capsules, and reflection coach. - Regenerated `packages/skills-catalog/generated/catalog.json` so shipped metadata matches source skill frontmatter. - Added a Vitest regression guard that caps repo skill source descriptions and generated catalog descriptions at 300 characters. ## Verification - `pnpm --filter @paperclipai/skills-catalog build:manifest` - `pnpm --filter @paperclipai/skills-catalog test` — 5 files passed, 19 tests passed - `pnpm --filter @paperclipai/skills-catalog typecheck` - Final measurement: 29 source `SKILL.md` files, max description length 215 chars, 5,449 total description chars, estimated 1,363 description tokens at 4 chars/token. Note: the clean PR worktree was created from `origin/master` and contains only this commit, but it does not have `node_modules`; running `pnpm --filter @paperclipai/skills-catalog test` there failed at tool/package resolution (`vitest`, `tsc`, `@paperclipai/shared`). The dependency-equipped workspace passed the commands above before the commit was cherry-picked onto the clean branch. ## Risks Low risk. This changes skill metadata and tests only. The main risk is over-trimming a useful trigger phrase, mitigated by keeping explicit “use when” clauses and leaving detailed guidance in the skill bodies. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR. Feature PRs that overlap with planned core work may need to be redirected — check the roadmap first. See `CONTRIBUTING.md`. ## Model Used OpenAI GPT-5 Codex coding agent via Paperclip/Codex, with shell and file-edit tool use. Exact API model ID and context window were not exposed in the runtime. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
