Getting it into your agent

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 | $0.00064 | $0.00958 |
| Opus 5 | $0.00032 | $0.00479 |
| Sonnet 5 | $0.00013 | $0.00192 |
| Haiku 4.5 | $0.00006 | $0.00096 |
Grade A, and why
plog scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks the agent to reveal its instructionslowSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
8. Report four concise groups: tracked, missed, uncertain, and excluded false positives. For each missed or uncertain item, provide source file, exact line range, symbol or purpose, and reasoning. Do not print full promp Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PromptLog
Run PromptLog from this plugin package. The user does not need a global plog installation.
CLI runner
Use this exact runner for every CLI operation, preserving the current project as the working directory:
node "${CLAUDE_PLUGIN_ROOT}/dist/index.js"
Never substitute a global plog command and never install PromptLog from inside this skill. If the runner fails because Node is older than 22.13, report the detected Node version and the minimum requirement.
Arguments: $ARGUMENTS
Route the request
- No arguments: run
statuswhen.promptlog/config.jsonexists; otherwise runinit, followed by the semantic audit below. init: runinit, then perform the semantic audit whenintelligence.modeishost-agent.scan: runscan --json, then perform the semantic audit whenintelligence.modeishost-agent.audit: ensure the project is initialized, then perform only the semantic audit.watch: start the bundledwatchcommand as a background process. Report how to stop it.ui: start the bundleduicommand as a background process and report the localhost URL. Do not expose it on0.0.0.0unless the user explicitly requests that.- Any other PromptLog subcommand: pass the arguments to the bundled runner unchanged. Supported commands include
status,inventory,diff,note,notes,note-delete,export,rollback,add,ignore,unignore, andconfig. - A plain-language phrase: map it to the closest action, state the action selected, and continue.
Do not leave foreground watch or ui processes blocking the session.
Semantic audit
The deterministic scanner is the first pass. This audit is an independent, repository-aware second pass designed to find prompt surfaces that naming and syntax heuristics can miss.
- Read
.promptlog/config.json. Respectscanner.include,scanner.exclude, andintelligencesettings. Ifintelligence.modeisnone, skip this audit and say so. - Run
inventory --json. This inventory intentionally contains locations and hashes but not prompt text. - Locate actual model invocation boundaries in the included source: provider SDK calls, agent/framework constructors, message arrays, prompt templates, completion/chat/generation calls, and project-specific model wrappers.
- Trace prompt-bearing arguments backward through helpers, imports, object properties, arrays, joins, template functions, and configuration. Also inspect instruction files that are loaded into an agent or model at runtime.
- Treat a value as a prompt when its text or assembled result is supplied to a model as instructions, system/user/assistant content, a template, examples, tool guidance, evaluation criteria, or agent policy.
- Exclude UI copy, logs, ordinary documentation, tests/fixtures, generated output, dependencies, and historical
.promptlogdata unless the application actually sends that content to a model at runtime. - Compare every confirmed prompt surface with the inventory by normalized source path and overlapping line range. Do not call something missed merely because its stable name differs.
- Report four concise groups: tracked, missed, uncertain, and excluded false positives. For each missed or uncertain item, provide source file, exact line range, symbol or purpose, and reasoning. Do not print full prompt content when
sendFullPromptByDefaultis false. - Never register a missed prompt silently. When
requireUserConfirmationis true, present the proposedaddoperations and wait for explicit approval. After approval, run one bundledadd <file> --start <n> --end <n> --name <stable-name>operation per accepted item, then reruninventory --jsonand summarize the result.
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.

plog is a skill published in the GitHub repository shrimaanshreyash/Promptlog (2 stars, last pushed 2mo ago), licensed MIT. It adds 64 tokens to every session and 958 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

opensrc
Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for"…
lx
Codebase exploration tool that reads many files or whole directories in a single call, with per-file headers, glob include/exclude filters, function/type skeleton extraction (signatures only, no bodies), and head/tail line slicing.
audit
Audit phase. Parallel review: code quality + security + tests. Semantic dedup of cross-mode findings. Outputs PASS/WARN/FAIL per dimension. Validates spec coverage.
discover
Trigger: vague/unfocused request or solution-without-problem. Also invoked via /discover command. Reframes goal before acting.
eval
Quality and performance evaluation with baseline comparison. Sub-modes: correctness, performance, quality, regression. Outputs PASS/WARN/FAIL per dimension. Use for pre-ship evaluation or regression checks.
orbit
State-persisted autonomous pipeline: spec → go → audit → eval → ship → evolve in one command. Auto-detects direct/council/interactive mode. Crash-recoverable via PIPELINE-.json. Hands-off until PR.
