compound

compound is a skill for Claude Code, Codex from Andamio-Platform/coach. It costs 14 tokens per session (2,424 once invoked), scanned A, original, MIT.

A knowledge-capture tool for course development. It extracts useful patterns, rules of thumb, and accuracy information from earlier course work and feeds them into later planning and review steps.

In plain words
What is it for?
Use it after reviewing course quality, readiness, lesson types, or a complete course to record lessons that can improve future drafts and assessments.
Why use it?
It helps future course-development runs benefit from past decisions and mistakes instead of starting with the same assumptions every time.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

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.

Security

Grade A, and why

compound 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 4d 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.

Skill: Compound Knowledge

Description

Extracts patterns, heuristics, and calibration data from course development artifacts. Feeds knowledge back into /draft-slts, /assess-slts, /self-assess-readiness, and /classify-lesson-types to make each run smarter than the last.

Invocation Modes

/compound                          # Interactive: asks what to compound
/compound quality-review           # Compound from specific phase
/compound readiness                # Compound from readiness assessment
/compound classification           # Compound from lesson type classification
/compound --course=go-pbl --rollup # Full course retrospective

Instructions

Path Resolution

Resolve file paths based on your execution context:

  • Plugin context (${CLAUDE_PLUGIN_ROOT} is set): Read knowledge from ${CLAUDE_PLUGIN_DATA}/knowledge/ (user data), falling back to ${CLAUDE_PLUGIN_ROOT}/knowledge/ (seed data). Write all knowledge updates to ${CLAUDE_PLUGIN_DATA}/knowledge/ — never modify the plugin's bundled seed data.
  • Clone/symlink context (default): Read and write knowledge at knowledge/ relative to the project root.

All knowledge/ paths referenced below follow this resolution. In plugin context, substitute the appropriate prefix.

Phase Selection

If invoked without arguments, present phase options:

## What would you like to compound?

| # | Phase | Source Artifact | Extracts |
|---|-------|-----------------|----------|
| 1 | quality-review | 02-slts-quality-review.md, 01-slts.md | Successful rewrites, quality issues |
| 2 | readiness | 05-readiness-assessment.md | Tier distribution, context shopping list |
| 3 | classification | 04-lesson-type-classification.md | Verb patterns, edge cases, heuristics |
| 4 | lesson-build | lessons/*.md | Actual vs self-assessed confidence |
| 5 | context-add | assets/ + re-run readiness | Which resources unlocked which SLTs |
| 6 | rollup | All artifacts | Full course retrospective |

Which phase? (Or specify course: --course=slug)

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.
