AuC is a Python framework for running a single AI agent with an asynchronous, pluggable reasoning loop, language-model adapters, permission levels, and observable events. It is used to build coding and conversational agents with tools, security checks, web interfaces, background jobs, evaluations, and isolated execution. The catalogue entries are skills for extending its agent workflow.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00125 | $0.01783 |
| Opus 5 | $0.00063 | $0.00892 |
| Sonnet 5 | $0.00025 | $0.00357 |
| Haiku 4.5 | $0.00013 | $0.00178 |
Grade A, and why
ecc-recipes 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 9d 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.

How it starts
The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ECC Recipes
One entry point for "which group of ECC slash-commands runs my workflow, in what order, and when do I stop." Also browses every command-group recipe family.
Fills the gap between two existing skills:
ecc-guide— lists commands and where to read docs, but as a flat catalog.prompt-optimizer— matches a task to components, but outputs a single prompt, not a multi-command group with run-order and stop condition.
This skill adds: family grouping + run-order + stop condition.
When to Activate
- "Which command group do I run for ?"
- "What's the command sequence to build an MVP / fix a defect / refactor?"
- "Show me all ECC command-group recipes" (catalog mode)
- "How many workflow pipelines does ECC have?"
- User invokes
/ecc-recipeswith or without a description.
Do Not Use When
- User wants the task done now — route to the actual command, don't describe it.
- User wants deep docs for ONE command — use
ecc-guide. - User wants a draft prompt rewritten — use
prompt-optimizer.
Core Principle
Answer from current files, not memory. The command set changes; never
hardcode counts or member lists. Read the live commands/ directory each run,
then classify into families.
Live reads
Resolve the commands directory (first that exists), then list names:
for D in \
"$HOME"/.claude/plugins/marketplaces/ecc/commands \
"$HOME"/.claude/plugins/cache/ecc/ecc/*/commands \
./commands \
./.claude/commands \
"$HOME"/.claude/commands; do
[ -d "$D" ] && CMD_DIR="$D" && break
done
[ -z "${CMD_DIR:-}" ] && { echo "No ECC commands directory found."; return 1; }
find "$CMD_DIR" -maxdepth 1 -name '*.md' -exec basename {} .md \; | sort
Optionally read manifests/install-*.json if present for richer grouping. Use
the smallest set of reads needed.
Family Classification (by prefix)
Group command names by leading prefix; map known singletons by hand. Families are derived live — the table below is the classification rule, not a frozen list.
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.

ecc-recipes is a skill published in the GitHub repository ufy2024/AuC (1,090 stars, last pushed 1mo ago), licensed MIT. It adds 125 tokens to every session and 1,783 once invoked, about $0.0006 per session on Opus 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.
