Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00385 |
| Opus 5.5 | $0.00012 | $0.00154 |
| Sonnet 5.5 | $0.00006 | $0.00077 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
cancel-loop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Cancel Loop
Plugin Resource Resolution
<PLUGIN_ROOT> is notation. Replace it with a concrete absolute plugin root before every resource read or command:
- Codex: Start from the directory containing the absolute selected
SKILL.mdpath, then ascend two directories (skills/<name>-> plugin root). - Claude Code: Bind it to the injected
${CLAUDE_PLUGIN_ROOT}value.
Before cancellation, read <PLUGIN_ROOT>/lib/driver-interaction.md and follow
its cross-platform capability-binding rules.
Bind the invocation arguments as SKILL_ARGS for $go-workflow:cancel-loop by
reading <PLUGIN_ROOT>/lib/skill-arguments.md with this Claude Code compatibility payload:
$ARGUMENTS
Invocation
- Codex:
$go-workflow:cancel-loop [loop-name] - Claude Code:
/go-workflow:cancel-loop [loop-name]
With no loop name, cancel every active loop owned by the current repository. With a loop name, cancel only that loop and leave unrelated loop state untouched.
Execute Cancellation
if [ ! -x "<PLUGIN_ROOT>/scripts/cleanup-loop.sh" ]; then
echo "ERROR: Plugin cache stale. Refresh the go-workflow plugin and restart the active assistant."
exit 1
fi
/bin/bash "<PLUGIN_ROOT>/scripts/cleanup-loop.sh" "$SKILL_ARGS"
Report the helper output exactly. Do not claim a loop was removed when the helper reports that no matching active loop exists.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cancel-loop is a skill published in the GitHub repository gopherguides/gopher-ai (21 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 385 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
