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 | $0.00036 | $0.00473 |
| Opus 5 | $0.00018 | $0.00236 |
| Sonnet 5 | $0.00007 | $0.00095 |
| Haiku 4.5 | $0.00004 | $0.00047 |
Grade A, and why
session-mode 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 6d 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
session-mode
Resolves project-level single-session vs multi-session execution and prints
role-specific identity prompts. Once project.session_mode is present in
.agentic-rounds/state.yaml, do not ask again per round.
Workflow
-
Read
.agentic-rounds/state.yamland the round handoff. -
If
project.session_mode.modeis already set, treat it as fact and skip the recommendation/choice step. -
If no project-level mode exists, generate a recommendation:
arcgentic session-mode recommend \ --round <round-id> \ --handoff <handoff-path> -
Print recommendation, confidence, reasons, suggested role identities, and override instructions before asking the user to choose.
-
Print only the identity handoff prompt needed for the next role:
arcgentic session-mode prompt \ --round <round-id> \ --handoff <handoff-path> \ --mode multi-session \ --role developerV1 valid roles:
developer,auditor,closeout. -
For V2 Codex-native orchestration, generate the fixed-role host plan instead of per-round role prompts:
arcgentic v2-session-plan \ --state .agentic-rounds/state.yaml \ --host codexV2 session roles are fixed to
Orchestrator,Planner,Developer, andAuditor.close-roundis an orchestrator-owned command, not a session role.
Boundaries
- Do not enter developer work before the mode gate is resolved.
- Do not re-ask the user when project-level mode is already stored.
- Do not claim single-session auto-audit when dispatch transport is unavailable.
- In V1, developer, auditor, and closeout identity prompts must remain separate.
- In V2, keep exactly four fixed role sessions and never create round-numbered role threads.
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-mode is a skill published in the GitHub repository Arch1eSUN/Arcgentic (292 stars, last pushed 24d ago), licensed MIT. It adds 36 tokens to every session and 473 once invoked, about $0.0002 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.

debt-ops-init
Write or refresh a "Tech debt operations" section in the project's AGENTS.md so the team shares one source of truth for debt-ops disciplines. Run ONLY when the user explicitly asks to set up, install, or initialize debt-ops disciplines — never auto-invoke. Idempotent; only the managed section changes, other sections…
init
Write or refresh the ## Tech debt operations section in CLAUDE.md so a team shares one source of truth for debt-ops disciplines and cached quality commands. Idempotent. Only the managed section changes; other sections are untouched. Invoked explicitly via /debt-ops:init (solo users get the same content from the…
add
Register a deferred decision in the debt registry. Trigger by judgment, not a marker scan, whenever a future reader would ask "why this way?": an unmade decision, stub, loosened type, bypassed check, swallowed error, a default picked "for now", or a TODO/FIXME/HACK/XXX marker. Trigger immediately whenever you defer…
metrics
Print a debt-ops health summary from the metrics log, covering registration rate, hook feedback action rate, ADR creation, and AI-authored share. Use when the user asks for "debt-ops metrics", "debt health", "registry stats", or invokes /debt-ops:metrics. Read-only, never writes the log.
review
Audit the debt registry, rank survivors by churn × Fowler quadrant, surface a top-N list, then walk paydown on user follow-up. Use when the user asks to review debt, see what to pay down, work through entries, or invokes /debt-ops:review. Stale entries drop with drop A,B,C.
debt-ops-add
Register a deferred decision in the tech-debt registry. Trigger by judgment, not a marker scan, whenever a future reader would ask "why this way?": an unmade decision, stub, loosened type, bypassed check, swallowed error, a default picked "for now", or a TODO/FIXME/HACK/XXX marker.
