Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01074 | $0.01074 |
| Opus 5 | $0.00537 | $0.00537 |
| Sonnet 5 | $0.00215 | $0.00215 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade A, and why
syllago CLAUDE.md 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 5d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Syllago
A package manager for AI coding tool content. Import, export, and convert content (rules, skills, agents, prompts, hooks, commands, MCP configs) between providers. Hub-and-spoke conversion through syllago's own canonical format.
Content registries are community-driven — syllago provides the tooling but does not own or curate registry content.
Build and Test
make setup # Configure git hooks (run once after clone)
make build # Compile binary to cli/syllago
cp cli/syllago ~/.local/bin/syllago # Install to PATH (REQUIRED — see below)
make test # Run all tests
IMPORTANT: After any Go code change, you MUST do BOTH steps before declaring work complete or asking the user to test:
- Build —
make buildwrites the compiled binary tocli/syllagoonly. The Makefile has no install target. - Install to PATH —
cp cli/syllago ~/.local/bin/syllago(or whichever pathwhich syllagoresolves to). The user'ssyllagocommand runs the binary on PATH, NOTcli/syllago. Skipping this step means the user tests against a stale binary and your fix appears not to work — wasting a full debug cycle.
If you only ran make build, the work is NOT done. Both commands are mandatory; treat them as one indivisible step.
IMPORTANT: Always run cd cli && make fmt before committing Go changes. CI enforces gofmt and will fail on unformatted code. A pre-commit hook also blocks unformatted commits locally.
For TUI visual changes, regenerate golden baselines after tests pass:
cd cli && go test ./internal/tui/ -update-golden
Key Conventions
- Hooks and MCP configs merge into provider settings files (JSON merge). All other content types use filesystem (files, dirs, symlinks).
- Hook canonical format is defined in
docs/spec/hooks.md. Canonical event names are provider-neutral snake_case (before_tool_execute, notPreToolUse). Canonical tool names are descriptive lowercase (shell,file_read,file_edit). Provider-native names (CC'sPreToolUse, Gemini'sBeforeTool, etc.) live in theHookEvents/ToolNamesmaps intoolmap.go— Claude Code is a regular provider entry, not the implicit key. - Go conventions: see
cli/CLAUDE.md - TUI component patterns: see
cli/internal/tui/CLAUDE.md
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.

syllago CLAUDE.md is an instructions file published in the GitHub repository OpenScribbler/syllago (15 stars, last pushed 2d ago), licensed Apache-2.0. It adds 1,074 tokens to every session, about $0.0054 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 2026-08-30.
