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 | $0.00022 | $0.02230 |
| Opus 5 | $0.00011 | $0.01115 |
| Sonnet 5 | $0.00004 | $0.00446 |
| Haiku 4.5 | $0.00002 | $0.00223 |
Grade A, and why
estimate-point 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 5d 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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Estimate Point (Phases 4-5)
Personas MUST be dispatched in parallel, never sequentially.
Invariant Principles
- Parallel dispatch protects independence: All personas point each ticket in one batched call; sequential dispatch lets later personas anchor on earlier numbers and collapses multi-agent consensus.
- Disagreement triggers reconciliation: Splits greater than 1 Fibonacci step mean someone is missing context — re-dispatch with cross-visible reasoning; on persistent disagreement take the higher value and flag it.
- 34 halts, never estimates: A consensus value of 34 stops the pipeline and loops back to scope for splitting before any multiplier or buffering runs.
- Conservative on ambiguity: When personas disagree on complexity, take the HIGHER classification; never apply M_AI < 1.0 to High-complexity work to flatter AI tooling.
- Consensus is synthesis, not voting: The output is the reconciled median of independent expert reasoning, never one persona's number with the others discarded as "wrong".
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.

estimate-point is a command published in the GitHub repository axiomantic/spellbook (10 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 2,230 once invoked, about $0.0001 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 2026-09-03.
Other commands, from other repositories
report-issue-with-atomic
Open an issue against the atomic-claude repo itself (bugs/feature requests with the installed config, not the user's current project).
report-issue
Open a atomic GitHub issue via gh. Bug report or feature request — auto-detect from user's description.
save
Save current work state for next session. Creates/updates .planning/ files (CHECKPOINT.md, STATE.md, settings.json) so Heimdall resumes with full context. NOT a rewind — saves forward progress. Run before closing a session or at any milestone.
status
Show current Heimdall state — project phase, active agents, quality gates, conflicts.
beads-swarm
Execute beads with parallel agent swarm (dependency-aware).
beads-loop
Execute beads iteratively until all tasks complete.
