What it does
Archer is an agent skill from autonomous-ai/openharness. Shape a Jev Archer range (target speed, bullseye size, shots), then verify Jev plants the slow targets and leaks the fast ones.
Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: The ultimate harness for coding agents and beyond. All your agents. All your machines. One command center. Start with code, then follow your curiosity and build across… The licence is MIT.
Example prompts

What it can do on your machine
Read from SKILL.md and the folder at commit 50da5db. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Archer loads about 673 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 363 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.
Safety
Auto-check passed
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.

Craft — Jev Archer
Jev Archer is a 1-D tracking game: a target slides across a line and Jev nudges the aim to track it, releasing an arrow every window. The craft is curating the target speed and the bullseye size into a range that shows a real decision loop — Jev plants the slow ones and leaks the fast ones.
The decision loop
Each tick the viewer gives Jev its current read: the aim x, the target x, and how many ticks until the arrow releases. Jev answers one Choice:
Which way do you nudge the aim this tick? LEFT_FAST / LEFT / HOLD / RIGHT / RIGHT_FASTThe mock reads the same lines and nudges toward the target. The physics — how far the target slides per tick and how precise the bullseye is — is what makes it hard or easy, not randomness.
Reading and shaping the range
{
"speed": 0.6, // target slides this many slots per tick
"bullHalf": 1.0, // half of the bullseye in slots when the arrow releases
"targetWidth": 24, // range width in slots
"shots": 16, // arrows in the session
"style": "track the target"
}speedis the honest limit. At0.4–0.6the target slides less than the aim corrects in one tick, so Jev stays glued and it's nearly a clean day. Past ~1.2the target outruns the aim each tick, the aim trails, and the arrow releases off-center.bullHalfis the precision knob. Tight (0.4) demands the aim land within a whisker; wide (1.5+) lets Jev string clean days together.stylechanges how Jev plays. "Hug the target, correct instantly" vs "read its direction and lead the motion" produce visibly different aim behavior.

Shaping tension
A good range should have a deliberate flip: pick a speed where it's calm, and know what speed (or
what bullseye) makes Jev start to leak. Start at 0.6, then either speed the target up to 1.2+ for
a busy, miss-heavy range, or tighten the bullseye for a precise one. Report the flip: does Jev plant
a clean day at the calm setting and leak when sped up?
Verifying
node "$JEV_DSH/toolchain/check.mjs"Then run the real loop and watch: a good range plants the slow and leaks the fast. A dull range never leaks; a broken one leaks even on a slow target. Report whichever extreme you see — don't hide it.
Definition of done
archer.jsonpassescheck.mjs.- Jev visibly tracks the target and plants it at a calm speed.
- Speeding the target up (or shrinking the bullseye) visibly raises the misses — the knobs actually matter.

Shape a Jev Archer range (target speed, bullseye size, shots), then verify Jev plants the slow targets and leaks the fast ones.
How do I install Archer in Claude Code?
Run `npx skills add autonomous-ai/openharness --skill archer -a claude-code`. Or copy the skill folder (store/agents/jev-archer/skills/archer in autonomous-ai/openharness) into .claude/skills/archer in your project. Claude Code loads it when a task matches its description.
How do I install Archer in Codex?
Run `npx skills add autonomous-ai/openharness --skill archer -a codex`. Or copy the skill folder (store/agents/jev-archer/skills/archer in autonomous-ai/openharness) into .agents/skills/archer in your project. Codex loads it when a task matches its description.
Can I use Archer in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add autonomous-ai/openharness --skill archer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/archer, .gemini/skills/archer, .github/skills/archer and .opencode/skills/archer in your project.
What does Archer need to run?
Going by SKILL.md and its folder, Archer needs the command-line tools its instructions call (node).
Does Archer access the network?
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.
Is Archer safe to install?
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.
What licence does Archer use?
Archer is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Archer use?
About 673 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
