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 | $0.00209 | $0.01433 |
| Opus 5 | $0.00105 | $0.00717 |
| Sonnet 5 | $0.00042 | $0.00287 |
| Haiku 4.5 | $0.00021 | $0.00143 |
Grade A, and why
aristotle 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Aristotle — Dispatcher
CRITICAL: DO NOT load REFLECT.md, REVIEW.md, LEARN.md, or CHECKER.md. All logic is handled by MCP orchestration tools. NEVER mention internal mechanism names (MCP tool names, action names, workflow_id, prompt fields) to the user — describe outcomes in plain language only.
ROUTE
cmd = first argument or ""
MATCH cmd:
"learn" → CALL orchestrate_start("learn", args_json) → execute ACTION
"sessions" → CALL orchestrate_start("sessions", "{}") → execute ACTION
"review" → CALL orchestrate_start("review", {sequence: N}) → execute ACTION → REVIEW FEEDBACK
* → GOTO PRE-RESOLVE
PRE-RESOLVE (reflect only)
result = CALL orchestrate_start("reflect", {target_session_id: "", session_file: "",
focus: "last", user_language: <detect>, project_directory: <cwd>})
MATCH result.action:
"fire_sub" → Bridge handles snapshot. execute ACTION. STOP.
"pre_resolve_needed" → GOTO SNAPSHOT-EXTRACT
"notify" → Display result.message. STOP.
other → execute ACTION. STOP.
## SNAPSHOT-EXTRACT (non-Bridge / Claude Code only)
IF session_list is available:
target_session_id = session_list()[0].id
content = session_read(target_session_id)
Bash("mkdir -p ~/.config/opencode/aristotle-sessions")
Write snapshot JSON (schema v1, source: "llm-session-read") to
~/.config/opencode/aristotle-sessions/{target_session_id}_snapshot.json
session_file = that path
ELSE:
session_file = ""
IF any step fails: session_file = ""
result = CALL orchestrate_start("reflect", {target_session_id, session_file,
focus: "last", user_language: <detect>, project_directory: <cwd>})
→ execute ACTION. STOP.
ACTION EXECUTION
If action is pre_resolve_needed:
GOTO SNAPSHOT-EXTRACT (in PRE-RESOLVE section above).
If action is fire_o:
- Call task(category="unspecified-low", run_in_background=true, prompt=o_prompt)
- When notification arrives, call MCP
orchestrate_on_event("o_done", {workflow_id, result}) - Execute returned action per this section
What ships with it
5 files 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.

aristotle is a skill published in the GitHub repository alexwwang/aristotle (17 stars, last pushed 4d ago), licensed MIT. It adds 209 tokens to every session and 1,433 once invoked, about $0.0010 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.
