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 | $0.00056 | $0.00358 |
| Opus 5 | $0.00028 | $0.00179 |
| Sonnet 5 | $0.00011 | $0.00072 |
| Haiku 4.5 | $0.00006 | $0.00036 |
Grade A, and why
insight-harvester 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 10d 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.
What it actually says
Insight Harvester
Turn raw observations into configuration improvements with evidence.
Inputs
memory/learnings/*.md(raw, per-session) andmemory/learnings/CONSOLIDATED.md- Pasted output of the built-in
/insightscommand, when available - Recent
docs/specs/*/story files with## Findingswalls
Method
- Cluster, do not enumerate. Group observations by underlying cause, not surface symptom. "Worker touched out-of-scope file" three times across different specs is ONE pattern.
- Demand evidence. Every pattern cites at least 2 occurrences (file + date). Single events are noted, not acted on.
- Map pattern -> smallest fix. Prefer, in order: a path-scoped rule in
.claude/rules/> a line in an agent prompt > a CLAUDE.md constitution change (most expensive context-wise - last resort). - Write fixes as diffs, not advice. "Add to
.claude/rules/api.md: 'All new endpoints require an authz check; see wiki/auth-invariants'" - copy-pasteable. - Specificity test: a rule that would equally apply to any random repo is too generic to add. Project-specific or nothing.
Output
A ranked table: pattern | evidence (n, links) | proposed diff | expected effect | rollback note.
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.

insight-harvester is a skill published in the GitHub repository Black-coffe/vulyk (2 stars, last pushed 5d ago), licensed MIT. It adds 56 tokens to every session and 358 once invoked, about $0.0003 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 2026-08-31.

claude-md-review
Audit a CLAUDE.md file for the patterns that actually degrade Claude Code's output — vagueness, unnamed files, stale facts, and bloat. Use when asked to review, audit, improve, shrink, or fix a CLAUDE.md, and when a project's results feel inconsistent or Claude keeps rediscovering the same context.
config-validator
Validate AIWG configuration files and project setup for correctness and completeness.
summarize-transcript
Analyze and summarize a transcript, meeting notes, or discussion thread into a clear actionable document.
artifact-metadata
Manage artifact metadata, versioning, ownership, and review history across the SDLC lifecycle.
hook-regenerate
Rebuild AIWG hook files from currently installed framework manifests.
