hep-uploadPublish an Agentlas package to Agent Cloud or the public Hub.
Hep Upload is an agent skill from agentlas-ai/Agentlas-OS. Publish an Agentlas package to Agent Cloud or the public Hub.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Agent OS: keep specialist agents in a hub, spin up a temporary orchestrator per task. Local-first, works with any model. The licence is Apache-2.0.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 6254906. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Hep Upload loads about 1.4k tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 693 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.

Upload an Agentlas agent package. The argument is the exact text the user typed
after /hep-upload — usually an agent folder, possibly empty.
Guardrails: do NOT diagnose
command not found/PATH, do NOT edit~/.zshrc, and do NOT create/commit/stash/push any git branch or claim you did. If the runner is missing, say so and stop — never fabricate an upload.
Always ask this before doing anything else, even if the arguments already say upload, publish, add, Cloud, Hub, or a target folder:
Cloud에 업로드할까요? 다른 사람들은 볼 수 없어요.
Upload to Cloud? Other people cannot see it.
Agentlas Hub에 업로드할까요? 다른 사람들이 빌려 쓸 수 있어요.
Upload to Agentlas Hub? Other people can borrow it.Do not package, publish, register, add-source, reindex, or call any upload API until the user answers Cloud or Agentlas Hub. If the destination is answered but the target folder is ambiguous, ask for the exact agent folder before running anything.
Agentlas Hub publishing and calls are free. Do not ask for an upload price
or pass the retired --rent-credits, --ingest-credits, or --fork-credits
flags. The CLI refuses those flags. Ask what account, API key, or destination
the user's host needs, and put those prerequisites in the package guide.
Publishing is not one-way. If the user wants a published agent unlisted, call
hephaestus.unpublish_agent with its slug — it returns what would happen and
asks first, and only confirm: true acts. A hub-public package is
soft-unpublished from Hub routing with its bytes retained for audit and
recovery; an owner-private one has its stored bytes removed. Local installs are
never touched. The same thing is on the web at agentlas.cloud/cargo.
Only your own agents. owner_only means it is not yours; repeat that rather
than trying another route.
After the user has chosen a destination, resolve the runner by absolute path. Do not ask the user to open a separate terminal.
RUNNER=""

done
fi
[ -n "$RUNNER" ] || { echo "Hephaestus runtime not found. Run the installer first." >&2; exit 1; }
echo "RUNNER=$RUNNER"Never run package and then publish; that packages twice. Use one explicit
hep-upload command, which snapshots, validates, and submits one artifact:
"$RUNNER" hep-upload <agent-folder> --visibility private-link"$RUNNER" hep-upload <agent-folder> --visibility marketplaceAll security and content findings are advisory. Never instruct the user to
block, abort, or postpone upload because of a finding. Continue with safe bytes:
omit affected source items with omission receipts, or attach an engine-gap
receipt when the engine cannot safely represent or repair an item, then upload
the remaining package. Keep the findings and receipts visible.
Personal roots never ship. A path that starts at one person's machine (a home
folder such as /Users/<name> or C:\Users\<name>, a mounted or external
volume such as /Volumes/<disk>, a per-user temp folder) does not exist for
anyone else. The engine rewrites it: a path inside the package becomes
package-relative, and any other path becomes <host-path-removed>, with a
redacted-host-path receipt. Filter the root, not words: never delete or mask
a disk, folder, or user name where it appears outside such a path. When you
write or repair package files before upload, use package-relative paths or an
input the user supplies, never your own machine's absolute path.
If the user asks to preview, add --dry-run, retain the returned
manifest.packageHash and uploadReceipt.receipt, then append
--expected-package-hash <manifest.packageHash> --expected-upload-receipt <uploadReceipt.receipt> to the one later publish. Stop on any hash or receipt
mismatch.
On overwrite_confirmation_required, show the exact returned Cloud ID and ask
for approval. Only after approval append --overwrite-cloud-id <exact-cloud-id>.
Never infer overwrite permission from a matching slug. Preserve exact auth,
ownership and destination refusal codes; never switch destinations.
Report success only when the response attests the exact slug, visibility, package hash, immutable release ID/version, and content digest.

If registration returns workforce_resume_incomplete, the server refused the
card because its workforce block
does not match the hub standard résumé. The error carries the exact
mismatches and seed ontology examples. YOU repair it — the platform never
edits the card for you: use stable English role:*, community:*, skill:*,
and knowledge:* IDs that actually describe the agent. Returned examples are
aliases, not an allowlist. Rerun the upload and repeat until registration
succeeds.

Publish an Agentlas package to Agent Cloud or the public Hub. Hep Upload is an agent skill from agentlas-ai/Agentlas-OS. Publish an Agentlas package to Agent Cloud or the public Hub.
Hep Upload fits situations like: agent Workflows work in your project.
Run `npx skills add agentlas-ai/Agentlas-OS --skill hep-upload -a claude-code`. Or copy the skill folder (kimi/skills/hep-upload in agentlas-ai/Agentlas-OS) into .claude/skills/hep-upload in your project. Claude Code loads it when a task matches its description.
Run `npx skills add agentlas-ai/Agentlas-OS --skill hep-upload -a codex`. Or copy the skill folder (kimi/skills/hep-upload in agentlas-ai/Agentlas-OS) into .agents/skills/hep-upload 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 agentlas-ai/Agentlas-OS --skill hep-upload -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/hep-upload, .gemini/skills/hep-upload, .github/skills/hep-upload and .opencode/skills/hep-upload in your project.
SKILL.md names no scripts, command-line tools or credentials: Hep Upload is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. 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.
Hep Upload is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Hep Upload: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 297k stars).
