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 5.1 | $0.00077 | $0.01455 |
| Opus 5.5 | $0.00031 | $0.00582 |
| Sonnet 5.5 | $0.00015 | $0.00291 |
| Haiku 4.5 | $0.00008 | $0.00145 |
Grade A, and why
session-complete 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.
How it starts

Steps
1. Scan Conversation for Reasoning Artifacts
Extract:
- Decisions made →
[D]artifacts - Insights learned →
[I]artifacts - Errors resolved →
[E]artifacts with root cause - Ideas deferred with conditions →
[S]seeds (forward-looking ideas that surface when a condition is met)
For each, draft the inline format:
`[D] <conclusion> — invalidates if <trigger> [priority] [YYYY-MM-DD]`
`[I] <insight> — invalidates if <condition> [priority] [YYYY-MM-DD]`
`[E] <what went wrong> — root cause: <why> — fix: <what solved it> [settled] [YYYY-MM-DD]`
`[S] <idea> — activates when <condition> [priority] [YYYY-MM-DD]`
Optional expiry: If the conclusion is time-bound (free tier, trial, beta, seasonal, "for now"), add — expires: YYYY-MM-DD before priority. Do NOT add expiry to foundational architecture decisions.
Seeds are ideas that came up but weren't actionable yet. Look for "maybe later", "when we have X", "not now but eventually".
Where [priority] is derived from:
- Claude proposes confidence (high/medium/low)
- Ask user: "High or low impact?"
- Matrix: high confidence + high impact = critical, low + low = noise, etc.
[E]errors default to settled; once resolved → noise- In
--compactmode: skip impact prompt — default all tosettled
2. Contradiction Check
Before confirming, scan existing artifacts in _context.md for contradictions with new ones:
- For each new
[D]or[I], grep the Active Reasoning Artifacts table for overlapping topics - If a new artifact supersedes an existing one (same domain, updated conclusion):
- Mark the old artifact for eviction to
Decisions/withstatus: superseded - Show:
"#X superseded: <old> → <new>"
- Mark the old artifact for eviction to
- If a new artifact contradicts an existing one (conflicting conclusions, both may be valid):
- Flag:
"Conflict: new <artifact> vs existing #X — keep both, or resolve?"
- Flag:
- If no overlap → proceed normally
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.

session-complete is a skill published in the GitHub repository Aiyo28/memento-os (4 stars, last pushed 23d ago), licensed MIT. It adds 77 tokens to every session and 1,455 once invoked, about $0.0003 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 2026-08-31.
