linear-performance-tuningImprove Linear GraphQL latency and throughput by reducing field, connection, pagination, and polling cost.
Linear Performance Tuning is an agent skill from jeremylongshore/tons-of-skills-marketplace. Improve Linear GraphQL latency and throughput by reducing field, connection, pagination, and polling cost. Use when queries are slow, complex, or exhausting shared budgets. Trigger with "optimize Linear GraphQL", "reduce Linear query complexity", or "speed up Linear sync".
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live verification requires network access and an approved Linear workspace credential
It sits in Backend & APIs, covering GraphQL. It works with GraphQL. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepWebFetchWriteEditFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
linear.appFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
API_KEYACCESS_TOKENFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code; live verification requires network access and an approved Linear workspace credential
From compatibility in the SKILL.md frontmatter.
Linear Performance Tuning loads about 1.2k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 499 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/linear-performance-tuning/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Tune the measured operation rather than applying guessed delays, and preserve correctness with bounded pagination and reconciliation.
Use Read, Glob, and Grep to inspect code, configuration, and evidence. Use WebFetch only for current first-party Linear documentation and package metadata. Use Write or Edit only for requested implementation with known target files. Never write credentials, customer content, unrestricted environment output, or unredacted GraphQL variables.
Use a personal API key only for owner-controlled scripts, OAuth with PKCE for user-delegated applications, or an enabled client-credentials grant for approved automation. Personal keys use Authorization: <API_KEY>; OAuth tokens use Authorization: Bearer <ACCESS_TOKEN>. Store credentials server-side in an approved secret manager.
Treat app approval, team access, scope changes, credential creation, rotation, revocation, and production access as owner-approved actions.
hasNextPage is false.Do not create, reveal, rotate, or revoke credentials; authorize an OAuth app; change scopes or team access; create, mutate, archive, or delete workspace data; configure or re-enable webhooks; import or export data; change roles, SCIM, or audit streaming; transmit diagnostics; change paid entitlements; or perform another production mutation without explicit approval from the accountable owner. Keep diagnosis read-only unless implementation was requested.
Return the workspace and team scope, auth mode without credential value, files and contracts inspected, exact operation names, evidence collected, validation result, sensitive fields redacted, remaining risk, accountable owner, approval state, and rollback or next action.
| Condition | Response |
|---|---|
| Complexity above 10,000 | Shrink connections, fields, or page size before sending the query. |
| Budget exhausted | Coordinate producers and wait for reset metadata; do not spin retries. |
| Pagination misses data | Use stable cursors and explicit updated-time reconciliation. |
| Cache leaks visibility | Scope keys by workspace/team/access context or disable the cache. |
Use a compact handoff that makes scope, mutation authority, and verification evidence reviewable.

Improve Linear GraphQL latency and throughput by reducing field, connection, pagination, and polling cost. Linear Performance Tuning is an agent skill from jeremylongshore/tons-of-skills-marketplace. Improve Linear GraphQL latency and throughput by reducing field, connection, pagination, and polling cost.
Linear Performance Tuning fits situations like: queries are slow; exhausting shared budgets; with optimize Linear GraphQL; reduce Linear query complexity.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill linear-performance-tuning -a claude-code`. Or copy the skill folder (skills/.curated/linear-performance-tuning in jeremylongshore/tons-of-skills-marketplace) into .claude/skills/linear-performance-tuning in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill linear-performance-tuning -a codex`. Or copy the skill folder (skills/.curated/linear-performance-tuning in jeremylongshore/tons-of-skills-marketplace) into .agents/skills/linear-performance-tuning in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jeremylongshore/tons-of-skills-marketplace --skill linear-performance-tuning -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/linear-performance-tuning, .gemini/skills/linear-performance-tuning, .github/skills/linear-performance-tuning and .opencode/skills/linear-performance-tuning in your project.
Going by SKILL.md and its folder, Linear Performance Tuning needs credentials named API_KEY and ACCESS_TOKEN. Our summary lists: A credential in API_KEY; A credential in ACCESS_TOKEN. Its frontmatter pre-approves these tools: Read, Glob, Grep, WebFetch, Write, Edit. Compatibility (from SKILL.md): Designed for Claude Code; live verification requires network access and an approved Linear workspace credential.
SKILL.md names 1 domain. As links in the text: linear.app. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Linear Performance Tuning is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 817 tokens, read only when the agent opens those files.
