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 | $0.00031 | $0.00963 |
| Opus 5.5 | $0.00012 | $0.00385 |
| Sonnet 5.5 | $0.00006 | $0.00193 |
| Haiku 4.5 | $0.00003 | $0.00096 |
Grade A, and why
session-report 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
The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use
Long-running branch spanning multiple Claude Code sessions. The eventual commit (or squash) needs the why behind the work, but git diff alone loses that. Run /session-report at the end of a session to capture intent for the future commit-message synthesis.
Opt-in only. Does not auto-fire.

- Working tree clean AND no unstaged changes since last commit →
refused: no changes since last commit — nothing to report.
Steps
-
Determine branch scope key:
git branch --show-current. If empty (detached HEAD), usegit rev-parse --short HEADand warn the user:detached HEAD — report scoped to <sha> not a branch.
-
Compute paths:
- Dir:
atomic where --json'sreportsfield — already branch-scoped, with the legacy fallback folded in. Never construct it by hand. - Filename:
<YYYY-MM-DD-HHMM>-<slug>.md. Slug from$ARGUMENTSif provided; otherwise infer from the most prominent change in the working tree (one or two kebab-case words). - On filename collision (same minute + same slug): append
-2,-3, etc.
- Dir:
-
Gather signal:
git status --porcelain— list of touched files (staged + unstaged).git diff --statandgit diff --cached --stat— magnitude per file.- Recent conversation context — what was tried, what was rejected, what the user clarified mid-flight.
-
Write the report: seed the computed path from the embedded template —
atomic template session-report > <path>— then fill every<angle-bracket>placeholder (frontmatter +## What changed+## Why+ optional## Open threads) and delete the guidance comment. Ifatomicis absent or the verb errors, stop:document template unavailable (atomic template session-report failed) — install/update the atomic binary. cannot proceed. -
Report path to the user:
wrote <reports-dir>/<file>.md, using thereportspath fromatomic where --json.

Voice
atomic-writing voice at the length budget it gives a short-lived state file: bullets and short paragraphs, no narrative. Not atomic output style, which governs Claude's replies rather than file contents. Internal context that the commit-message synthesis will read.
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-report is a command published in the GitHub repository damusix/atomic-claude (112 stars, last pushed 9d ago), licensed MIT. It adds 31 tokens to every session and 963 once invoked, about $0.0001 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 2026-08-30.

autocommit
Toggle auto git commits on/off for this project. Run without args to see status, or with "on"/"off" to set.
fix-tests-execute
Phase 2 of fixing-tests: Fix Execution - investigate, classify, fix, verify, and commit each work item.
simplify-transform
Apply verified simplifications with user approval. Part of simplify- family.
verify
Run verification commands and confirm output before making success claims. Use before committing, creating PRs, or claiming work is complete. Evidence before assertions, ALWAYS.
commit
Based on the above changes, create a single git commit.
align
Context-aware alignment. In plan mode it audits the active plan and folds the amendments in. Otherwise it reviews the branch, a named branch, or a pull request against Ion's principles, authors a fix plan, and after approval implements and commits the fixes.
