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.

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 →
- medium Rogue Agent · line 3 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00209 | $0.01433 |
| Opus 5.5 | $0.00084 | $0.00573 |
| Sonnet 5.5 | $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 2mo 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 (18 stars, last pushed 2mo ago), licensed MIT. It adds 209 tokens to every session and 1,433 once invoked, about $0.0008 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 2026-08-30.
