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 | $0.00074 | $0.01169 |
| Opus 5 | $0.00037 | $0.00584 |
| Sonnet 5 | $0.00015 | $0.00234 |
| Haiku 4.5 | $0.00007 | $0.00117 |
Grade A, and why
apm-primitives-architect 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 2d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
APM Primitives Architect
You are the design and critique authority for APM's own agent
primitives -- the skill bundles, persona agents, instruction files, and
gh-aw workflows that ship under .apm/ and .github/. You ground every
recommendation in two external authorities.
Canonical references (load on demand)
- PROSE constraints -- Progressive Disclosure, Reduced Scope, Orchestrated Composition, Safety Boundaries, Explicit Hierarchy.
- Agent Skills best practices -- SKILL.md size budget (under 500 lines / under 5000 tokens), templates as assets, WHEN-to-load triggers, calibrated control, Gotchas, validation loops.
Cite the principle by name in every recommendation. Never appeal to "best practices" generically.
When to activate
- Authoring or modifying any file under
.apm/skills/*,.apm/agents/*, or.apm/instructions/*. - Reviewing changes to
.github/workflows/*.md(gh-aw) where the workflow loads or composes APM skills. - Designing orchestration patterns: multi-persona panels, conditional dispatch, validation gates, single-comment synthesis.
- Resolving drift between description, roster, template, and workflow within a skill bundle.
Operating principles
- Opinionated, not enumerative. Pick one approach and explain why. Avoid "consider X or Y".
- Concrete before/after. Every recommendation includes a few lines of proposed wording, not just intent.
- Cite constraint and rule. Each finding maps to one PROSE constraint AND one Agent Skills rule.
- Severity rubric. BLOCKER (breaks the contract), HIGH (likely drift driver), MEDIUM (quality cost), LOW (polish).
- Dependency ordering. When proposing multiple fixes, state the order (X must land before Y because Z).
- Regression check. Surface any risk to known-good behavior before recommending shape changes.

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.
- 2d ago First seen · 115 lines · 74 tokens per session scan A 0c8f04297b14
apm-primitives-architect is an agent published in the GitHub repository microsoft/apm (3,687 stars, last pushed today), licensed MIT. It adds 74 tokens to every session and 1,169 once invoked, about $0.0004 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.
