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 | $0.00018 | $0.00989 |
| Opus 5 | $0.00009 | $0.00495 |
| Sonnet 5 | $0.00004 | $0.00198 |
| Haiku 4.5 | $0.00002 | $0.00099 |
Grade A, and why
clare2-corpus-capture 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 11d 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLARE2 Corpus Capture
Use deterministic lifecycle hooks to send useful agent interactions into the
local CLARE2 corpus. Sessions are captured per-project under a shared user
corpus at ~/.config/clare/corpus, partitioned by project name. Each project
builds its own adapter.
Agent support matrix
| Agent | Capture supported | Notes |
|---|---|---|
| Claude Code | Yes | Visible message deltas, elicitation, tools, subagents, compaction, and session lifecycle in .claude/settings.json |
| Codex 0.144.1 | Yes | Final responses, elicitation, tools, subagents, and compaction in .codex/hooks.json |
| GitHub Copilot | Yes | Elicitation, tools, subagents, compaction, failures, and lifecycle in .github/hooks/clare2-corpus.json; assistant text fallback is opt-in |
| Roo/Zoo Code | Prompt-level | .roo/rules/clare.md emits equivalent normalized events; upstream has no deterministic repository hook API |
Configuration
clare-installer.sh sets CLARE2_CORPUS_ROOT automatically, creates
~/.config/clare/corpus, and symlinks the project's corpus/ directory there
so the pipeline container resolves the same data. Run:
./scripts/clare-installer.sh --update --target /path/to/project
If you need to set it manually:
export CLARE2_CORPUS_ROOT="$HOME/.config/clare/corpus"
CLARE2_SESSION_FILE takes precedence when an existing wrapper or command has
already initialized a session. CLARE2_PROJECT_ID overrides the project name
derived from git rev-parse --show-toplevel basename (used by default).
Text content is redacted and limited to 12,000 characters by default. Set
CLARE2_CAPTURE_MAX_CHARS to a smaller non-negative integer, or 0 to disable
prompt, response, and correction text capture while retaining lifecycle and
tool outcome events.
Copilot's documented agentStop hook does not expose assistant text. By
default CLARE records a privacy-safe turn_complete event. To explicitly opt
in to parsing Copilot's unstable private transcript format for assistant text,
set CLARE2_COPILOT_TRANSCRIPT_FALLBACK=1 before starting Copilot.
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.

clare2-corpus-capture is a skill published in the GitHub repository jketreno/clare (5 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 989 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 2026-08-31.
