tlc-spec-lean is a skill in tech-leads-club/agent-skills, last changed 31 Oct 2026. It can run shell commands, reach the network, name web addresses and bundle scripts — read the findings before installing.
Spec-driven feature work that freezes obligations instead of the plan: one human-reviewed plan with EARS criteria, path, entities, interface and one-way doors, then proof-backed checks, then build, then an independent Verifier. Use when the user says "tlc-spec-lean", "plan feature", "specify feature", "write the checks", "build this plan", or "verify work". Do NOT use for standalone design documents unattached to a feature, architecture decomposition analysis, or work that already has a task list or checklist to execute.

From the files and frontmatter at commit 1da2195. This is how much a skill can do, not whether it is risky.
Pattern check
Pattern check: nothing flagged · commit 1da2195 · 3 Nov 2026
We checked every text file in this skill, at commit 1da2195 on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses
The open format from agentskills.io, held to the strictest version of each rule among the agents we check.

Reference files over 100 lines with no table of contents at the top: references/checks.md (210 lines), references/memory.md (110 lines), references/plan.md (341 lines), references/verify.md (108 lines) and scripts/fixtures/plan.md (118 lines). B5
Fix: Add a short list of the sections at the top of each.
- Note
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

Fix: Add a short list of the sections at the top of each.
- Note
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
The description is 526 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
